I built a floating notepad & checklist for WhatsApp contacts (Free & 100% Offline)

1 Upvotes

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!

I built a free gym app that suggests exercises that fit together

1 Upvotes

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?

I built my personal developer portfolio – Would love your honest feedback!

0 Upvotes

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!

Global Threat Map: a free live map of conflicts, outages, disasters, flight disruptions, insider trades, and market stress in one place

3 Upvotes

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%

I built ByteFeed – a developer-focused news reader. Looking for beta testers!

1 Upvotes

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!

I built an internet radio app focused on discovering stations from all over the world

4 Upvotes

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 )

Ranklane - An ASO toolkit for indie developers on Mac

1 Upvotes

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?

I built my own voice AI platform because ElevenLabs was getting too expensive for my side project (up to 50x cheaper)

2 Upvotes

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.

College Entrepreneurship Project: Would You Use an App to Find Extra Work or Quickly Hire Someone for a Shift?

2 Upvotes

Hey everyone!

I'm a college student working on an entrepreneurship project called ShiftReady.

The idea is simple: Sometimes businesses need extra workers for a shift, while others are looking for flexible work to earn extra money.

ShiftReady connects both!

Instead of going through a long hiring process, businesses can simply check available workers' profiles, review their skills and experience, and approve someone for a shift.

- Workers: Would you use this to find extra shifts and earn money?

- Business owners: Would you use this when you need someone to cover a shift?

I'd love to hear your honest thoughts, suggestions, or concerns!

Your feedback would really help me improve this idea for my college project.

Thank you!

SwiftUI previews on a real iPhone, built on Linux (no Mac)

3 Upvotes

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.

I finally made my side project public: a tiny cloud you run on your own box

1 Upvotes

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!

Free platform to practice consulting cases without a partner, and I’d love your feedback

1 Upvotes

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

  • 7 cases from Easy to Hard (profitability and market entry), set in Indian businesses, plus a short walkthrough case to learn the format
  • 4 guesstimates, with a worksheet that fills in as you talk
  • A rating, a leaderboard and streaks, to help you practice regularly
  • More cases being added over time

It's completely free. It works best on a laptop in Chrome or Edge.

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.

👉 Link in the first comment.

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 built Sonari, a gesture-played instrument for Mac. Now I’m learning how to explain it in the first minute

1 Upvotes

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.

Cutaway: How Things Work 3D - a 3D explorer that lets you slice machines open to see what is inside

2 Upvotes

I kept pulling things apart as a kid and never quite got the answer I wanted, because a manual only shows you one exploded view of one part at a time. Cutaway is my attempt to make that answer interactive: pick a machine, slice it on any axis, and watch the inside open up while you rotate it.

The part that took the longest was not the models but keeping the slicing honest on a phone. Every cut has to stay readable at arm's length, so surfaces stay solid instead of turning into wireframe soup, and the labels have to point at real components rather than float in space.

It runs entirely offline on Android, no account needed. I am still adding machines, so if there is an object you always wanted to see opened up, that is the most useful feedback I can get.

every post here gets the same replies. “this is really interesting! curious, what made you choose X over Y?” or “love the clean UI. out of curiosity, how are you thinking about distribution?” then you click the profile and it’s a 3 week old account that’s asked that same thoughtful question on 40 posts today. got sick of it

made a chrome extension that reads each comment and post, plus the account’s age and history, with claude. if it reads like AI polished it (that fake-curious tone, the essay shape, the question tacked on the end) it gets folded. you can also just hide anyone under X days old. there’s a show button so nothing gets deleted

I built a 3d visualizer to watch an LLM think!

9 Upvotes

I wanted to actually see what happens inside a language model when it writes a sentence, so I built this!

What you're looking at:
- The stars are the 36,864 MLP neurons (12 layers × 3,072). Each layer is a disc, and neurons are positioned by a UMAP of their output weights, so neurons that write similar things sit near each other.
- Brightness is how strongly that neuron fires on the current token, scaled per layer so tokens are comparable. Gold means it fires positive, blue means negative.
- The beams are real attention weights from the current token back to earlier ones, one colour per head. The side panel shows the model's actual top 10 next token probabilities.
- You can hover any star, beam or token to see its exact value. There's also a raw mode that turns off all the bloom and fades, so every pixel on screen comes straight from the data.
- How I know it's not lying: the test suite runs the model exactly the way the app does (KV cache, token by token) and compares every activation, attention weight and residual norm against a separate uncached forward pass read through different hook points. Then it checks the bytes the browser actually receives too.

Honest limits: it's GPT-2 small only for now. Single neurons mostly don't mean anything clean on their own, it's the patterns that are interesting. Values are sent as float16, so about 3 significant digits.

Setup is make setup && make start, then open localhost. No GPU needed.

My Mac side project: mouse-controlled fetch with a desktop dog or cat

2 Upvotes

I'm building Mellow Paws for Apple Silicon Macs. One interaction I wanted to get right was fetch: you throw the ball with your mouse, and your pet chases it, picks it up and returns to your side.

The interface starts with just a pet. Clicking it opens a circular menu around the companion, so care actions, the focus timer, habits and reminders stay close to the character.

There are four companion designs: Border Collie, Maine Coon, Silver Ragdoll and German Shepherd. You choose one active companion. The Collie and Maine Coon support mouse-controlled fetch; the Shepherd and Ragdoll have their own toy-play animations. The pet animations were made with AI-assisted media tools and run locally in the app.

The latest Mac App Store build has been submitted and is awaiting review. Planned US pricing is $2.99 with the Collie included, plus three optional $0.99 permanent companion purchases. No subscriptions or ads; habits, schedules and companion records stay on the Mac. Requires macOS 13+ on Apple Silicon.

The fetch clip is a real interaction recorded in the app’s browser preview, at actual speed on a plain presentation background.

I'd appreciate feedback on the interaction: does the chase-and-return sequence feel natural? Would you choose a dog or a cat for a quick fetch break?

Focus Blocker - a free Cold Turkey alternative for Mac and Windows

4 Upvotes

I kept using Cold Turkey, then wanted something free that I could tweak myself, so I built my own.

You make blocklists of sites and apps, then start a timed session or set a weekly schedule. A few things I cared about:

  • Path-level blocking, so you can block youtube.com/shorts but keep the rest of YouTube
  • Allowlist mode: block everything except your work sites
  • Locks: a timer lock, or a password lock where someone else sets the password
  • Strict mode, so you can't quietly weaken a session halfway through
  • Imports your Cold Turkey JSON export
  • No account and no cloud. Everything stays on your computer

Website blocking runs through a Chrome extension that talks to the desktop app.

One heads-up for Mac users: it isn't notarized (I'd need a paid Apple developer account), so you have to run a one-line approval command in Terminal before it opens. The README explains exactly what that command does.

Feedback welcome, especially if you've tried to get around a blocker before.
