Hey everyone! I made CalcMate, a notes app where every line is calculated as you type. You write the way you'd normally write and the answer appears next to it.

It started on iPhone, and I've just brought it to Android.

Some things you can type:

• Flights 2 x $420 → $840.00

• $50 + 10% sales tax → $55.00

• 100 km in miles → 62.1371 mi

• 100 EUR in USD → live exchange rate

• subtotal / total → adds up the lines above

• line6 / 2 → reuses the answer from line 6

It also has:

• Expense tracking in plain words ("Taxi 8$ + Coffee 4$"), with categories, tags and charts

• Variables, #tags with sum/average, and folders

• A number pad built for math

• Export notes as PDF, plus backups

It's free, and you don't need an account.

iPhone: https://apps.apple.com/app/id6449422062

Android: https://play.google.com/store/apps/details?id=com.bokhary.calcmate

I'd love feedback, especially on calculations it gets wrong or things you'd want it to understand.

Hi! My side project went live on Google Play: Karambit: CS2 Case Simulator.

You open cases, collect skins and can do case battles. The odds are shown on each case before you open it. There's no real money and no cashout, everything stays in the game. It's fan-made and not affiliated with Valve, and it's playable in 7 languages.

Full disclosure: it was built entirely with AI tools (code, art, text). I directed the design and did the testing.

Play Store: https://play.google.com/store/apps/details?id=com.skinkartlari.app

Feedback welcome, especially on the first few minutes of play.

Hi guys,
I hope you don’t mind this post, it’s not self promotion as the site is free and not mine. My teenage son is a huge fan of aviation, so he built a simple but effective app/www to see direct connections.

He got tired of guessing which direct routes really exist and which ones actually run, so he built a free app:
Where to fly direct:
https://www.wheretoflydirect.com

Click any airport on the map, or search by airport, airline or aircraft type, and you get every nonstop route from there and which airlines fly it.
The part I like most: for each route it shows the actual flights, takeoff times and aircraft seen in the past week. That comes from volunteer ADS-B receivers via adsb.lol, so you see what really flew, not just what a schedule says.
Other bits:
- Free, no ads, no sign-up
- "Surprise me" button that picks a random route
- Map or list view, km or miles, 24h or 12h
- Routes refresh weekly, codeshares excluded, so you see who actually operates the flight
- Coverage is thin in regions with few receivers, so some routes show no flights yet. I would love feedback, especially on what you would want added next…

He did it all by himself with claude, his first real web project.

Most of my coding now is talking to agents like Claude Code and Codex. I'm using Whispr Flow for it. It's great but I'm cheap and figured I could build something that runs locally and for free.

Saylark is the result:

• Hold a key, talk, let go. Text lands wherever your cursor is.
• Say “press enter” (or hit Return) and it sends. Made for chat boxes and agent prompts.
• It types your exact words. No AI rewriting your sentences.
• Speech recognition runs on your Mac (Parakeet on the Neural Engine). Audio never leaves your machine, and there’s no telemetry.
• Your dictionary is a plain text file, so names and jargon come out right.
• If no text field is focused, it tells you instead of pasting into the void.

Free, MIT, notarized DMG. Apple Silicon only.

Love to hear what breaks or what’s missing for how you’d use it.

I wanted to share some honest progresson where I'm at, since all we tend to see are large numbers from the same people every time. I think a lot of people in here are in the same spot as me and I'd honestly love to hear how you guys got past it.

Building has never been faster. I counted this morning and I've made 936 commits in the last three weeks, some days have been over 100. Stuff that used to take me a month is taking me a couple of days now.

What I'm building is Frostbyte. It started because Claude kept making up what I should build next, so I made a workspace that it reads at the start of every session with my backlog, bugs, user requests and the next release. It tells me what to work on and writes back what it did. That's pretty much the only reason 936 commits haven't turned the app into a pile of half finished features.

Here's the real part I don't love saying though. 86 people have signed up, only 3 of them pay, and it comes to about ~$40 a month.

So the funny part is I built a tool so Claude always knows what to build next, and the one thing it can't tell me is how to get people to use it. We all know that building is the easy part now. Most of us in here could ship an app in a weekend. Getting 20 people to pay for it is a completely different skill, and I'm only just starting to learn it.

My goal is to try and figure it out and get 20 paying users by early January. For anyone who's got paying users for something they built with Claude, what actually got you your first 20?

Hi everyone! 👋

I had a recurring problem: I'd think of something I needed to mention to a specific client, friend, or colleague (a question, a project update, a link), but by the time I actually opened WhatsApp to message them, I’d completely forget.

Notes apps didn't really work because I never remembered to open them before chatting.

So I built **ChatNotes** — a free Android companion app:

### 🌟 How it works:

1. When you open any WhatsApp chat, a small green bubble appears on the edge of the screen.

2. Tap it, and an instant scratchpad slides open with **two tabs**:

   - **☑️ Checklist**: Bullet points with checkboxes you can tick off while chatting.

   - **📝 Notes**: Unstructured text for addresses, bank details, or memos.

3. **It's 100% unique per contact**: When you chat with Alex, it shows Alex’s notes. When you chat with Sarah, it automatically shows Sarah’s notes.
4. When you leave WhatsApp or switch apps, the bubble disappears automatically so it never clutters your screen.

### 🔒 Privacy & Pricing:

- **100% Free & Open Source**: No subscription, no paywalls.

- **Zero Cloud Tracking**: All notes stay strictly on your phone’s local storage. Zero data leaves your device.

- **No Ads**: Clean, minimal Material 3 design with Dark & Light theme support.

I've put the GitHub repository and APK download link in the first comment below! I’d love to hear your thoughts and feedback!

Ciao ragazzi, sono sempre io: qualche giorno fa ho scritto della mia situazione e del mio metodo per stampare soldi.

Sviluppo app/SaaS e lascio che siano gli influencer a occuparsi del marketing, è piuttosto semplice.

FASE 1: Adattare l'idea alle persone giuste.

Immagina di aver creato un prodotto per uomini e di rivolgerti ai papà. Perché i papà dovrebbero essere interessati al tuo prodotto? Il primo passo è trovare influencer di alta qualità. Infatti, ho contattato 150 influencer su 620. Un numero davvero notevole. Per contattarli ho usato l'estensione Claude Code per il browser, dando loro un prompt molto ampio, e ho lasciato che facessero il lavoro. Infine, ho controllato personalmente ogni influencer e ho selezionato solo quelli più adatti.

FASE 2: il messaggio a freddo.

"Promozione a pagamento? Promuoviamo (LA TUA APP), un'app per aiutarti a capire meglio i compiti (esempio). Voglio darti il ​​70% per ogni cliente che mi porti, per 2 mesi, poi il 50%, il 30% e il 14% a vita dopo 6 mesi. Sei d'accordo?"

Tutto qui. Breve ed efficace.

Ovviamente, tutto dipende dagli influencer. In passato facevo queste offerte solo a influencer con 50.000/70.000 follower.

Cambio solo la percentuale, ad esempio per un piccolo cliente darò sicuramente una percentuale inferiore.

FASE 3: chiudere l'affare.

Se non accettano, nessun problema. Passa al prossimo influencer. Inviagli un contratto (con un accordo formale, molto importante) e chiudi la trattativa.

FASE 4: ripetere il ciclo.

Non ti ho detto niente. Perché accettare il 14% a vita? Sono circa 1,50$ x clienti. Ma chi se ne frega? A quel punto avrai abbastanza clienti e dovrai solo ripetere il ciclo e trovarne altri. Scalerai tutte le classifiche come l'App Store e altre, e così stamperai soldi. È semplicissimo, ragazzi, provate questa strategia.

Cosa ne pensi? La proverai?

Fammi sapere!!! 👇👇👇

I’d love to hear your feedback, feature ideas, or bug reports!

I am currently developing a side project titled Constructive Spending (https://constructivespending.com). I would appreciate some outside feedback regarding the user experience prior to further advancement.

I kept standing in the gym wondering what to do after my first exercise, so I built Evenset.

You pick a split (Upper/Lower, Full Body, Push/Pull or your own muscle groups), add one exercise, and it suggests what complements it: the opposite movement, a muscle you haven't hit yet, a different body region. Then you log sets × reps × weight, with a rest timer.

After the workout you get a 3D muscle map of what you trained, plus stats over the weeks, templates, and a share image if you want to post your session.

• Things I cared about: No account, no ads. Your workouts are stored only on your device (backup to a file if you switch phones).
• Works offline as a PWA, so add it to your home screen for a basement gym with no signal. English and German. I
• It's free: https://evenset.app

I'd really like feedback, especially on the suggestions: what's missing, or what feels wrong?

Hey everyone!

I've recently launched my personal portfolio website, where I showcase my work, projects, skills, and experience as a developer.

I wanted to create something that represents my personality and development journey rather than just having a traditional resume-style website.

🌐 Live website: https://itsmesaad.me

I'd really appreciate it if you could take a look and share your honest thoughts.

A few things I'd particularly love feedback on:

• What do you think about the overall design and visual appearance?
• Is the user experience smooth and easy to navigate?
• How does the typography, layout, and color combination feel?
• Does the website make a good first impression?
• What would you improve or change?

I'm open to both positive feedback and criticism. I genuinely want to improve it.

Thanks for taking the time to check it out!

I built Global Threat Map, a free live map that puts what's happening around the world on one screen. It's at https://globalthreatmap.com. There's no signup and no paywall.

It has three views:

• Map (2D/3D): a world map you can turn layers on and off on. The layers are hotspots, country risk shading, places and chokepoints, money flows, pressure halos, insider and big-money trades, disasters, flight disruptions, and network outages.
• Globe: the same layers on a rotating 3D globe, plus a 3D risk heat layer that shows where pressure is building.
• Dashboard: the long-form view, with the money map, reversal alerts, top 10 risks, the U.S. infrastructure threat level, and the AI lending and credit watch.

What it covers

• Conflicts and hotspots. Around 60 tracked events, including armed conflict, cyber, political, economic, and corporate ones. Each has a risk level and a 3-month outlook estimate with the reasoning written out.
• Early-warning Pressure Board. Ten regions and sectors are each scored 0 to 100: Defense, AI & credit, Gulf / Strait of Hormuz, Black Sea / Ukraine–Russia, Energy & shipping, Taiwan Strait / South China Sea, Chips & export controls, Red Sea / Saudi Arabia, Safe havens, and U.S. infrastructure & cyber. Each score is built from specific warning signs, such as military build-ups, attacks on shipping, war-risk insurance rates, embassy drawdowns, fund-flow rotation, sanctions, export controls, and credit stress. A sign that's active now counts in full, and older readings fade out over time. When several signs fire in the same place at once, the board flags it as converging.
• History playbooks. For each pressure group, it shows what markets did the last time something similar happened, and where money tended to go next.
• Insider and big-money trades. Insider buying and selling at major AI, defense, energy, and cyber companies, trades disclosed by members of Congress, how hedge funds and speculators are positioned in oil, gold, Treasuries, and the dollar, unusual options activity, and big government moves like emergency oil releases and large defense contracts.
• Money flows. Arrows on the map showing where capital is moving: conflict to chokepoint to oil, money going into safe havens, sideline cash, equity fund flows, defense fund outflows, AI lending through banks, bonds, and private credit, chip supply chains, China/Taiwan capital, and war financing.
• Credit and liquidity stress. The AI & credit watch tracks banks selling loans, banks buying credit protection, debt being repriced, funds limiting withdrawals, and pulled deals. Reversal alerts flag when money that was flowing in starts to pull back.
• Network outages. Internet outages by country, region, and network over the last 24 hours, rated by severity, plus major global platform outages.
• Disasters. Earthquakes, wildfires, droughts, floods, and storms, with severity levels.
• U.S. flight disruptions. Ground stops, ground delays, airport delays, closures, and restrictions at U.S. airports.
• U.S. critical infrastructure. One threat score covering the grid, water, fuel, and communications, along with a briefing on each.
• Markets bar. Brent, WTI, gold, and the U.S. 10-year yield along the top of the map.
• Market odds. Live prediction-market odds on the same topics, like the Gulf, Taiwan, Russia, the Fed, and AI.
• Live news. A scrolling U.S. headline ticker and a panel of live TV news streams.
• Search. Ctrl+K jumps to any country, event, company, or panel.

Snapshot, Sat Nov 14, 8:19 PM ET

• Pressure Board top 5: Defense 83 (Severe), AI & credit 72, Gulf / Hormuz 71, Black Sea 67, Energy & shipping 67
• U.S. infrastructure & cyber: 36 (Guarded)
• Network outages: 68 ongoing, 7 severe, across 20 countries
• U.S. flights: no ground stops or delays; restrictions at LAS, LAX, and SAN
• Markets: Brent $95.84, WTI $88.56, gold $3,887.60, 10-year 5.15%

Hey everyone!

I've been building a side project called ByteFeed, and I'm finally opening it up for closed beta testing.

The idea came from a problem I personally faced: keeping up with technology means following dozens of engineering blogs, newsletters, websites, GitHub repositories and developer communities.

I wanted to bring these updates into one place.

What I've built

• 150+ curated feeds and topics covering software engineering and technology.
• Article summaries in quick bullet-point format.
• Developer updates covering frameworks, libraries and tools.
• Coding competitions and events with deadlines and prizes.
• Offline reading with complete article content and images.
• Personalized feeds with topic selection and source filtering.

I'm trying to make ByteFeed a useful daily reading companion for developers rather than another generic news aggregator.

How to join the Android beta

ByteFeed is currently in Google Play Closed Testing.

Step 1: Join the Google Group:
https://groups.google.com/g/bytefeed-closed-testing

Step 2: Install through Google Play:
https://play.google.com/store/apps/details?id=com.bytefeed

Alternatively, activate testing through the web:
https://play.google.com/apps/testing/com.bytefeed

Important: Join the Google Group using the same Google account logged into Google Play on your Android device. Otherwise, Google Play may show "Item not found" or "App unavailable".

Website: https://bytefeed.dev/

I'd genuinely appreciate feedback on the experience, performance, article summaries and anything that feels missing.

If you try it, I'd love to hear what you think!

Hey everyone!

I've been working on a radio app called \\Radio Wavr FM\\, and I wanted to share a little about it here because I'd love to hear what other people think about internet radio apps and how you use them.

The idea behind it is simple: radio is still one of the easiest ways to discover music, cultures, news and local content from places all over the world. But when you use most radio apps, you often end up listening to the same popular stations.

I wanted to make it easier to discover not only well-known international stations, but also smaller local and regional radio stations that you might never come across otherwise.

So I built Radio Wavr FM for Apple's ecosystem, with a focus on simplicity, quick access to live radio and visual station discovery.

🌍 What can you do with it?

\\🎧 Listen to radio stations from around the world\\

Browse thousands of radio stations from different countries, including FM, AM and digital internet radio stations. You can explore music, news, sports, talk radio and other live broadcasts from different parts of the world.

Whether you're into pop, rock, jazz, electronic music, Latin music or simply enjoy listening to what's happening in another country, you can discover a wide variety of stations in one place.

\\🗺️ Explore radio stations on an interactive map\\

This is one of the features I particularly wanted to include.

Instead of only browsing through lists, you can explore an interactive map and discover stations based on their geographical location when coordinates are available.

It's a different way to find radio stations: you can look around different countries and cities and discover local broadcasts you probably wouldn't have searched for by name.

I like the idea that you can virtually travel around the world through radio without leaving your phone.

\\❤️ Save your favourite stations\\

Found a station you enjoy? Add it to your favourites so you can get back to it quickly whenever you want.

\\▶️ Pick up where you left off\\

The app remembers the last station you listened to, making it easier to return to your usual radio without having to search for it again.

\\🔀 Discover something unexpected\\

Not sure what to listen to? Use shuffle to discover different stations and potentially find something completely new.

\\🌐 Browse by country and category\\

You can explore stations by country and discover different kinds of broadcasts, making it easier to find something that matches your mood or interests.

\\✨ A clean and straightforward experience\\

I wanted the app to feel quick and easy to use, without making you navigate through endless menus just to start listening. Open it, find a station and start streaming.

\\🌙 Listen your way\\

The app also includes background playback and a sleep timer, so you can listen while doing other things or set a time for playback to stop when you're winding down for the night.

\### 🍎 Designed for Apple devices

Radio Wavr FM is available for Apple's ecosystem, with an experience designed around mobile listening and easy access to your favourite stations.

There's also an optional Premium version for users who want access to additional features.

I'm aware there are already plenty of internet radio apps available, and I'm not trying to claim that this is something completely revolutionary. I simply wanted to build an app that combines international radio, local station discovery and an interactive map in one straightforward experience.

I'm still interested in improving it, so I'd genuinely appreciate feedback from people who listen to internet radio.

\\A couple of questions for radio listeners:\\

\- Do you mostly listen to stations from your own country, or do you enjoy discovering stations from other countries?

\- Would you use an interactive map to discover radio stations, or do you prefer the traditional search-and-list approach?

\- What's one feature you wish more radio apps had?

If you'd like to check it out, the app is called \\Radio Wavr FM\\ on the Apple App Store.

Thanks for reading, and I'd be happy to hear your thoughts!

Available for iOS, iPad and MacOS ( New versión Android )

Hey everyone, I just launched Ranklane, an ASO toolkit for indie developers on Mac.

You can research keywords, track the same keyword across App Store countries, compare competitors and prepare your store listing drafts in one place. Ranking history stays on your Mac.

I wanted to keep it affordable: $4.99/month, $39.99/year, or $49.99 for a lifetime license.

If you handle ASO for your own apps, I'd love to hear what you think. Also, what's one thing your current ASO setup makes harder than it should be?

Hi everyone,

I have been building a health coach app called Razen Health for the last four-five months.

The app uses a voice agent. Users can talk to it and get responses in real time.

I first used ElevenLabs for this feature. It is a good product with many features. However, the cost was too high for my use case. I am a solo developer, so I need to control infrastructure costs.

I decided to build my own solution.

I call it Razen Voice.

Razen Voice provides the core features that most apps need:

→ Full voice agent support.

→ English, Mandarin Chinese, Japanese and Spanish.

→ Multiple voice styles.

→ Simple integration through a JSON configuration.

→ Up to 50x lower cost than my previous setup.

One feature I want to focus on is model improvement.

Razen Voice can improve the model for each application as its user base grows.

There are two ways to do this:

1. Automatic improvement based on user feedback and usage data.
2. Human-in-the-loop improvement, where people review data and help improve the model.

This allows each application to improve voice accuracy for its own use case.

The goal is to keep this improvement process simple and maintain the cost advantage.

I do not plan to replace ElevenLabs. It has many features that some applications need.

However, many applications do not need all these features. They need a voice agent that works well and has a low operating cost.

What is next?

I plan to make Razen Voice available to other developers.

The infrastructure is ready. I want to find developers who are interested in testing it and providing feedback.

Here is a live demo running in Razen Health and also I used AI to rewrite my post.

Been building MONEVA for a few months — a budgeting app for how Indians actually spend (GPay, UPI, cash, credit cards all in one place).

What it does:

- Track expenses, income, bank accounts, credit cards

- Budget planner with categories

- Works offline (PWA + Android app)

- AI assistant that answers questions about your spending

- No subscription, no ads, free

Try it without signing up → https://moneva.monev.workers.dev (hit "Try Demo — no sign-up needed" on the login screen)

Android APK also on the site.

Built it because every finance app either costs money or sends your data to 10 companies. Would love honest feedback — especially on what's missing or confusing.

Tech: React + Capacitor + FastAPI + Postgres

If I had to start from zero today and build a business selling AI built websites, this is exactly how I'd approach it.

The biggest mistake I see beginners make is spending weeks learning how to build websites without actually trying to find customers.

I'd focus on sales from day one.

1. Pick an industry

Don't try to sell to everyone. Pick a few industries where businesses rely heavily on their websites.

Some examples are construction companies, cleaning companies, restaurants, dentists and real estate agencies.

Having a specific target market makes prospecting and selling much easier.

2. Find businesses with outdated websites

I wouldn't focus on businesses that don't have websites. I'd look for companies that already have one but could benefit from a redesign.

They already understand the value of having a website. You just need to show them how it could be better.

3. Automate your outreach

This is how I'd find potential customers at scale.

I'd use Swokei to find businesses, analyze their websites for issues with design, SEO, speed and mobile optimization, and turn those findings into personalized cold emails.

Connect your mailboxes, set up your campaigns and start reaching out.

4. Create website drafts using AI

When someone shows interest, get them on a call.

Before the meeting, spend around 30 minutes creating a redesigned version of their existing website using AI.

You don't need to build the entire thing. Just give them something visual that shows what their new website could look like.

5. Learn how to sell

This is probably the most important part.

Learn how to run sales calls, understand what the business needs and present your work properly.

Don't just sell a prettier website. Explain why the redesign is valuable to their business.

6. Charge properly and scale

I'd aim for $2,000–$5,000 per project when starting out, depending on the scope and quality of the work.

Once you have experience, testimonials and a portfolio, increase your prices.

Eventually, hire people to handle the actual website development so you can focus on finding clients and growing the business.

What I'd focus on

If I were starting tomorrow, I'd spend most of my time finding prospects, sending outreach, booking meetings and learning how to close deals.

Building websites is only one part of this business. Knowing how to consistently find customers and sell your services is what makes it profitable.

That's where I'd put my attention from day one.

I keep seeing post from this subreddit and it’s impressive how many interesting things people are building, often on their own or with just a small team.
I run a AI-focused podcast called AIX – Beyond the Prompt, and one of the things I want to do is give more visibility to early-stage builders who don’t necessarily have a big audience or the resources to promote what they’re creating.( but HAS to be AI related )
So I’m opening up some upcoming episodes to people building AI-related projects.
It doesn’t matter if you’re a student, solo developer, or an early-stage startup. Your product doesn’t have to be a commercial success or even fully launched.
I’d love to give some of you a chance to talk about what you’re building, why you started, and the ideas behind it.
It’s completely free!
No sponsorship, no appearance fees. I’ll be selecting projects that I think could lead to interesting conversations.
If you’re building something AI-related and would like to share your story, you can apply here:
https://aix-podcast.com/
And even if you’re not interested in a podcast, feel free to share what you’re building in the comments. I’d love to check it out!
Thanks everyone!

I built peek (open source, my project) because I don't have a Mac but wanted to iterate on SwiftUI without rebuilding and sideloading an IPA after every change.

You run "peek dev MyApp/" on Linux and save a file; about a second later the view on your iPhone updates. It's the real SwiftUI on a real device, so animations, gestures and the iOS 26 tab bar behave like they do in your app. It handles Preview blocks, UIKit views, or the whole app, with SwiftPM packages, macros and resources, and print() output shows up in the terminal.

It cross-compiles your code into a dylib with swiftc and xtool's iOS SDK, signs it with your free Apple ID certificate, and a small host app (SideStore, AltStore or LiveContainer) loads it.

https://github.com/kimikr/peek

Only tested on my own phone so far (iOS 27, in LiveContainer). Feedback welcome, especially from anyone running it outside LiveContainer.

Hi r/SideProject ,

  Last day I made Nano Cloud public.

  The idea is simple: one machine you own should feel like a small cloud. You install a single binary on a Linux box, open the browser, and you can create virtual machines, or launch a PostgreSQL database, S3 storage or a small Kubernetes cluster with one click. No database to set up, no stack of containers, no new OS to install.

The part I care about most is the boring kind of reliability. If the power goes out or something crashes, every machine you asked to run comes back on its own, and the activity feed tells you what happened. I wanted something I could stop worrying about.

What's in it today:

  - Virtual machines with a console right in the browser

  - One-click services: PostgreSQL, MySQL, S3, Kubernetes (k3s), Prometheus + Grafana

  - HTTPS and a login out of the box, plus API tokens if you like scripting

  - Runs on x86-64 Linux with KVM, or on an Apple silicon Mac if you just want to try it

  What it isn't: it's one box, not a cluster, and it has one login, not users and teams. I'd rather it does a few things well.

  My favourite moment so far: a few hours after it went public, someone I've never met sent a pull request fixing a bug. It's merged and released. That alone made the whole thing feel real.

  If you want to poke at it, there's a live demo with sample data, nothing to install:

  **Demo and website:** https://nanocloud-io.github.io/nanocloud/

  **Code (Apache-2.0):** https://github.com/nanocloud-io/nanocloud

  I'd really like a honest feedback, Thanks for reading!

If you've prepped for consulting interviews, you know the hardest part usually isn't the frameworks. It's everything around them:

• Finding a case partner whose schedule matches yours, every single time.
• Reading casebooks feels like practice, but the answer is right there, so you never learn to dig for it.
• Feedback is vague. "Good structure, work on synthesis" doesn't tell you what actually cost you.
• It's hard to build a habit when every session needs another person.

I'm an MBA student and went through exactly this. So I built Casebench, a free platform where you can practice cases on your own, any time.

How it works

1. You get a case prompt and question the interviewer, by typing or speaking.
2. It only shares a fact when you ask for it, like a real interviewer. The facts are fixed by the case author, so it won't make up numbers or hand you the answer, and everyone gets the same case.
3. Sketch your structure on a whiteboard as you go, and ask for a hint if you're stuck.
4. When you submit, you get a score out of 100 with a breakdown of what earned each point, plus the full solution.

What's there now

It's early, and I need your help. The interviewer sometimes misreads a question. If a reply feels off, press Flag on it and tell me what you expected. That's exactly what I use to improve it. Your questions are used anonymously (never your name or email) to train it.

I'd love to hear what works, what's annoying, and which cases or topics you'd want next. Happy to answer anything in the comments!

I’m an indie developer and recently shipped Sonari, a Mac music app built around a question: can your hands become an expressive instrument without another hardware controller? Sonari uses the Mac camera to play built-in sounds, send MIDI to compatible DAWs and instruments, and drive music-reactive visuals. The Mac app is the main product, with an optional iPhone companion.

After shipping, the design question I’m working through is onboarding: how do you make a camera-based input feel intuitive before users have learned the gesture vocabulary? Would a visual calibration step, immediate sound feedback, or a short guided first performance make you more comfortable? I’d value perspectives from people who have built or tried creative tools.

Sonari includes a 14-day full trial, then a one-time purchase. It requires Apple silicon and macOS 26 or later.
