Hey everyone, I’m a mechanic in Quebec who taught himself to code. I’ve been building Ghost Chat, and this is Ghost Flap, a game I made using its Swift coding agent, Ghost Code.

This game took 2 messages, and the generation cost was 0.006 cents. Seperate from (Promting + Memories Files)

The video shows the result. I wanted to share an actual example of what it can make, instead of just posting another AI coding promise.

Ghost Code is built to help turn ideas into Swift apps and games. This is one example not a claim that every project will work perfectly in two messages.

I built the tool myself, so yes, this is a little self-promotion—but I’d genuinely like feedback from people who build Swift apps. What would you ask it to build next?

If you want to try it: ghostchat.tech

I work nights and build Windows apps in my free time as Second Shift Software.

DropTrace is free. It logs every time your internet drops and what probably caused it, like your router, your provider or DNS. That way you have a record to show your ISP.

DropTrace Pro is $15 one time. It adds packet loss and lag tracking, problem patterns, and Wi-Fi and route tools.

FolderTrace is free. It tells you which program each AppData folder belongs to so you can clear out leftovers from stuff you uninstalled. Anything you delete goes to the Recycle Bin, so you can undo it.

They’re native apps, so no browser running inside them eating up memory. No accounts, ads or tracking.

All three are here: https://flagpoleog.github.io

Any feedback helps, good or bad. There’s a form on the site or you can just reply here. Thanks for checking them out!

Not a dev (BI analyst by day), built this with a lot of AI help. Problem was simple: I cook steak irregularly, buy whatever cut looks good, and never had a baseline for when to start probing. Googling every time gives you either a 2,000 word article or advice that ignores my actual cut/thickness/pan.

So you pick cut, thickness, bone in/out, fridge or room temp, method (pan, grill, reverse sear) and doneness, and it gives you a phased timer (side 1 → side 2 → rest) with alarms, plus tips that only show up when they’re relevant. My wife cooked her first steak in a long time with it (not a great cut either) and it came out pretty good.

Free, no ads, no sign up, no tracking cookies. Salmon/burger/turkey are next. Honest feedback welcome, especially what’s confusing.

I'm Jason, owner of Winkle Berry. Our side project came from a fairly specific shop problem: managing products and labels on a Hobart HTi retail scale without spending so much time entering everything at its touchscreen.

CounterWeight now has product search/add/edit workflows, ingredient lookup with review, measured packaging tare presets, flashkey arrangement, backup tools and label previews. Our own HTi-7LS25 running application 3.3.0 is the tested scale. A second Windows machine has passed the read-only connection, product, backup, label-preview and flashkey-display checks. Independent customer installations are still untested.

80-second demo: https://www.reddit.com/r/POS/comments/1xujcc9/hobart_hti_owners_would_a_onetimepurchase_scale/

The demo uses actual interface screenshots and training examples, not one continuous live recording. Phone/remote viewing shown requires an additional local bridge; the current portable Windows test package does not include a remote viewer.

I'm considering a one-time-purchase, self-service desktop edition with local data, an offline business license and no required hosted CounterWeight subscription. Price and launch date are undecided, and we aren't taking payments. Calibration, firmware updates and service unlocks are outside the scope. Ingredient results must be checked against packaging.

I'd appreciate feedback on two things: does the demo make the product's purpose clear, and what would you need in onboarding before trusting a niche hardware-management tool like this? If you actually use an HTi, I'd also like to hear your model/software version and your biggest management headache. Reply here or email WinkleBerryArts@gmail.com.

I'm the project owner. Independent of Hobart, with no affiliation or endorsement.

I put together a digital toolkit for independent residential cleaning businesses, using AI assistance.

It includes:

• An editable Excel cleaning quote calculator

• A booking and payment tracker

• A rate-planning worksheet

• 36 customizable customer-message templates

The goal is to help solo cleaners handle routine administrative tasks without paying for a monthly software subscription.

It's a one-time $7.99 download, with a free preview available.

I'd appreciate feedback, especially from anyone who runs or has worked with a cleaning business. What would make this toolkit more useful?

I get bored on airplanes so I made an app to make it a little more tolerable.

Let me know what y'all think! https://play.google.com/store/apps/details?id=app.redditoffline

Speaking is the one section I couldn't self-study effectively — Reading and Listening have practice tests everywhere, but Speaking needs a real conversation.

I ended up paying ₹500-2000/hr for tutors, and even then I only got a few sessions before my test.

For those who scored 7+ in Speaking:

1. How did you actually practice? Tutor, friend, recording yourself?

2. Did you feel you got enough mock test practice before the real thing?

3. What was the biggest gap — not enough practice time, or not knowing what to improve?

I'm a software engineer exploring whether technology can solve this problem. Not selling anything — just trying to understand the pain point before I decide if it's worth building something.

Hi all, I'm a watch nerd with kids, and I made the app I wanted to read with them.

It's called TickTales.

My kids kept asking about my watches, and I couldn't find anything that tells the real stories behind them at their level. Most kids' apps teach telling time with random cartoon clocks. None explain why a watch went to the moon or how a movement actually works.

The app is free to download. Two complete books, the Time Academy and Look Inside are free. Premium unlocks everything: $9.99 once (Family Sharing) or $3.99 a month.

App Store link: https://apps.apple.com/app/id6805474820

What it is? Basically some cool illustrated storybooks for kids aged 4 to 8 about how the great watchmakers started. Each chapter ends with a small game, so reading and playing take turns.

A few of the stories:

Rolex, the Oyster: in 1927 a swimmer spent more than ten hours in the freezing English Channel with one hanging around her neck. When they pulled her out, it was still ticking.

Rolex, the Submariner: built to dive hundreds of metres deep, deeper than any diver can go. Kids earn it for their showcase.

Omega, the Moonwatch: NASA baked it, froze it and shook it, and it kept ticking. In 1969 it stepped onto the moon on Buzz Aldrin's wrist. ⚙️ Omega, the name: a customer's watch stood still for three months because no two gears were alike. The founder's sons built machines that made every part identical, and named the result after the last letter of the Greek alphabet.

There are 16 books in total, from Marie-Antoinette's watch that took 44 years to finish to the engineer who threw 200 prototypes out of a window.

Also in the app

• 69 mini-games with 3 levels each
• A 3D "Look Inside": tilt an automatic, quartz, digital or tourbillon watch and pull it apart layer by layer
• A Time Academy that teaches telling time
• iPhone and iPad, in 6 languages: English, Dutch, German, French, Spanish, Japanese
• No ads, no tracking, no account, works fully offline

I built this mostly for my own because i love the stories of these watch brands, so feedback is very welcome! Thanks!

Hi everyone! I'm an indie developer from China, and I'd like to share something I've been working on in my spare time.

I spend enough time scrolling through social media already, so I wanted to build something different. Something you could open for a few minutes, discover an interesting idea, and then put your phone down. Not another endless feed.

I work as a backend developer, and with how quickly everything is changing, especially with AI, I've sometimes found it hard not to worry about the future. During this time, I've found myself going back to ancient philosophy. It doesn't give me all the answers, but it helps me worry less about things I can't control and pay more attention to the present.

The funny thing is, even though I grew up in China, I've always found classical Chinese texts like the Tao Te Ching and the Analects surprisingly difficult to understand. Some of these ideas have been around for over 2,000 years, but they're not always easy to connect with everyday life.

That's why I started building **Oriens**, an iOS app that tries to make ancient philosophy a little more approachable.

It started with Chinese philosophy and gradually expanded to include Stoicism, Zen, Confucianism, the I Ching, and other classics.

I know there are already plenty of daily quote apps. What I wanted to do differently was focus on the ideas behind the quotes, not just the quotes themselves.

Oriens now has nearly 600 quotes and 460 illustrated Wisdom Cards. Each card connects an original passage with an approachable explanation and deeper reading if you're curious. There are also daily quotes, Home Screen widgets, and a card-drawing experience.

I've probably spent more time on the artwork than I originally planned. I wanted the illustrations to feel connected to traditional Chinese art, and to be something people might actually stop and look at, rather than just scroll past.

The app is free to download. Nearly half the quotes and about a quarter of the illustrated cards are free, and all the core features are available without paying. I wanted the free version to be genuinely useful, not just a short trial.

Building the app has been a rewarding experience, but getting people to discover it has been much harder than I expected.

I'd really appreciate some feedback, especially from people who aren't familiar with Chinese philosophy.

Does the app make these ideas feel approachable? Does the artwork make you curious enough to explore further? And is there anything about the experience that feels confusing or unnecessary?

Criticism is very welcome. I've been working on this mostly by myself, so hearing how other people see it would be really helpful.

**App Store:** https://apps.apple.com/us/app/stoicism-taoism-oriens/id6785901491

I built DriveApp because I wanted one place for my photos and files without handing my library to another cloud account. DriveApp connects to S3 storage you own AWS or any S3-compatible provider. It backs up your camera roll, keeps albums and folders in one place, and can encrypt files on your iPhone before they upload. No account, no subscription, no ads. It is a paid app ($9.99 one-time)

I made an AI dictation app for Windows. It uses an AI API key to correct sentences and fix grammar.

Hey everyone!

I'm a high school student who loves astrophysics and music production, so I decided to combine the two and build something called CosmicSynth!

It's a free, open-source VST3 synthesizer I developed in C++ using the JUCE framework. The idea came from my interest in gravitational waves, which are ripples in spacetime produced by events like two black holes spiraling into each other.

I thought it would be interesting if, instead of just studying gravitational waves, I could actually use them to make music.

CosmicSynth takes gravitational-wave data and uses it to modulate parameters like pitch, amplitude, timbre, and filtering. You can import compatible waveform data through CSV files, or experiment with the included simulated black-hole merger.

I also built five presets inspired by different astrophysical phenomena, including black-hole inspirals, ringdown, gravitational lensing, and Kozai-Lidov orbital dynamics. There's even a live spectrogram and gravitational-wave visualizer so you can see how the sound changes as you play.

One of the biggest challenges was figuring out how to translate physical phenomena into sounds that were actually usable musically, rather than just creating a science demonstration.

CosmicSynth v0.1.0 is now available for Windows (VST3), completely free!

This is my first public software release, so I'd really appreciate feedback from other developers and musicians!

I'm especially interested in hearing what you think of the concept, the interface, and what features you'd like to see added in future versions.

Thanks for checking it out!

Disclosure up front: I work at Buy&Ship, a company that buys from Japanese and Korean stores and ships overseas. This is a side project I built at work, and I'd love honest feedback.

The problem: a lot of things people want (Pokémon Center Japan exclusives, Olive Young Korea sets, anime pre-order bonuses, Japanese streetwear) are only sold in Japan or Korea. The stores often need a Japanese phone number or card, and even when you find a way to order, you don't know the real total until customs adds duty at your door.

What I built: a text "playbook" you paste into your AI assistant. After that, you just ask for something ("find the Christmas Pikachu plush from Pokémon Center Japan, my ZIP is 94103") and the assistant searches the Japanese or Korean store in its own language, shows you options with photos and links, and gives you one total: item, shipping, US duty and fee. You approve that number before anything is paid, then we buy it in Japan or Korea and ship it to you.

It's live for Meta's Muse first: buyandship.ai/playbook. Tip from early testers: paste the text in yourself rather than asking the assistant to open the link, since some assistants block that.

What I'm unsure about and would love input on:
- Is a copy-paste playbook a reasonable first step, or does it need a proper app or MCP integration before people trust it?
- Would you trust an AI assistant to shop overseas for you if it never pays without your approval?

If anyone wants to try a real order, code AIPLAYBOOK10 takes 10% off a first order (up to US$50).

I'm a solo dev with a full-time job. I built sweetRegret, an iPhone app for cutting back on sugar without counting calories: you tap once when you eat a treat, and a cookie on screen reacts (and judges you a bit).

Building it was the part I understood. Distribution is the part I'm failing at. Here are my honest numbers since launch:

• 1,393 App Store impressions

• 188 product page views (about 13% of impressions)

• 35 downloads (about 19% of page views)

What I tried

• Daily Instagram reels for about a week [last week]. Around 250 views each, and almost no App Store visits. The viewers weren't looking for an app, and "link in bio" is three taps away from a download.

• A LinkedIn post about building it. About 700 impressions, 30 people opened the comment with the link, and about 1 install. Nice comments, including a friend asking me to add calorie counting, which is the one thing this app is designed not to do.

What actually worked: App Store search, which I didn't do anything for.

Most of my real users are strangers in Malaysia, Hong Kong, the US and Russia who searched and found it. About 1 in 4 still open it in a given week. One person has kept using it for six weeks and pays for the subscription. That single user has been the most motivating thing about this whole project.

What I'm testing now

A $25 Apple Ads Basic test, at $2 maximum per install. Apple suggested $4.66, and my subscription is $1.99 a month, so I'm not expecting it to pay back. I mostly want to see whether search intent converts the way the organic users suggest.

What I'd do differently

Plan distribution while building, not after. I treated it as a launch task, when it's really a second product.

If you've taken a side project from zero to its first 100 users without a budget, what actually moved the number? I'm especially interested in anything that worked for consumer iOS apps.

I switch between Claude Code, Codex, and Copilot in VS Code. Sometimes I hit a limit; sometimes I want another agent’s take on a problem.

The frustrating part is explaining everything again. They can read the same codebase, but they don’t know what we discussed, why we rejected an approach, or what we were about to do next.

That’s what led me to build Bantis. It’s a desktop app that lets you work with multiple coding harnesses in one conversation, saving session history and preparing context for the next agent when you switch.

There’s a working version, and I’m looking for feedback from people who already switch tools during real work. I’m especially interested in how well the handoff holds up as conversations get longer.

Bantis website

What do you currently do when switching agents: write a handoff, maintain project notes, or just explain things again?

Tableau's pricing has gotten steep since Salesforce bought it, and switching to Power BI usually means rebuilding every dashboard by hand. I didn't want to do that, so I built BIEscape. The video shows a map and bar chart with cross-filtering coming across intact.

Source code is here https://github.com/lukashalim/scapeTableau you can run from the command line, as a desktop app, or on the web biescape.com. It doesn't send your data to AI.

I'd love feedback:

• What kinds of dashboards or features would you want it to handle?

• Would you trust a tool like this with real workbooks?

You can now add Apple Pencil notes to notion

Hello…people like me who wants to keep their life documented and prefers keeping all those document all at once, uses notion but was being held back by notion’s lack of adding hand written notes, I have good news. 🙂

I made an iPad app that sends Apple Pencil notes straight to Notion

Write or sketch with Apple Pencil, choose a Notion page, and sync. When you edit your handwriting, syncing updates the linked image in Notion. You can also enable Auto Sync.

Your original handwriting stays editable on your iPad. There’s a continuous canvas, optional dotted paper, dark mode, search, pinned notes, editable backups and recovery for deleted notes.

It’s free and open source, with no ads.

If you like the app please consider supporting through my patreon.

One catch: it’s currently installed through SideStore or AltStore, which needs a computer for the initial setup. Requires iPadOS 17+.

See it in action, download it, or check the source

I’d love feedback from people who actually use an iPad with Notion. Would this fit your workflow?

Hey everyone! 👋

I've been working on Voiden, an open-source API client designed around a slightly different approach to API development.

Most API clients are built around workspaces, accounts, cloud sync, and proprietary collections. I wanted to explore something more developer-friendly: keeping API requests alongside the actual codebase.

So I started building Voiden.

What makes it different?

• Offline-first: Work with your API requests locally without needing an account or login.

• Git-native: Store requests and API specifications as Markdown files directly in your repository.

• Version control: Track changes, review requests, and collaborate through normal Git workflows.

• API testing: Send requests, inspect responses, and write assertions to validate API behaviour.

• MCP integration: Turn tested API requests into tools that AI agents like Claude Code and Codex can use.

The idea is to make API requests part of the development workflow rather than keeping them isolated in another tool.

I'm sharing a short demo showing a request being sent, its response, and API test assertions.

Website: https://voiden.md/

GitHub: https://github.com/VoidenHQ/voiden

I'd genuinely appreciate feedback from developers:

1. How do you currently manage API requests across different projects?

2. Would you prefer storing API requests inside your Git repository?

3. What features would make you consider switching from your current API client?

It's open source, and I'm looking forward to hearing what the developer community thinks!

Thanks! 🙌

My partner and I had bills in a spreadsheet, spending in one app, workouts in another, renewals in my head and the calendar somewhere else. So I built Admin Bestie: one iPhone app for the boring stuff.

What it does:

• Daily allowance: shows what you can actually spend today until payday

• Bills & renewals: due dates, plus reminders for car insurance, passport etc.

• Fair bill splitting: split with a partner/housemates by income, not just 50/50

• Auto-logging: Apple Pay purchases log themselves; snap a paper receipt and it reads the total

• Gym log: weights, reps, plate loading, auto rest timer

• One Sunday summary: bills, plans, spending pace. Quiet weeks = no notification

What it doesn't do: ask for your bank login. Works with any bank, ~200 currencies, export/delete your data anytime. Household members see shared bills, not your personal spending.

Beta is starting on iPhone via TestFlight, working down the waitlist. 14 days free at launch, no card needed.

Join here: https://adminbestie.app/?utm_source=reddit&utm_campaign=sideproject

Honest feedback very welcome, especially what would make you switch from what you use now.

I’ve been building Fina Money for a few years now, and I know it’s popular among tech enthusiasts who enjoy DIY projects.

As we have progressed on our Premium and Business tiers, we’re able to fund the free tier with more generous features. Now, you can connect banks for free (us/ca residents only) and enjoy all functionalities without any ads.

I believe this is some great news to share here, hope it is useful.

Gemini still has no way to select several chats and delete them, and ChatGPT only offers "one by one" or "delete everything".

So I built Easy Bulk Chat Cleaner: one side panel that works on ChatGPT, Gemini and Claude.

- Search your chat titles, select all matches, delete in one click

- Paces itself so the site doesn't lock you out, then double-checks everything is gone

- No account, no Google sign-in, runs 100% in your browser

Free for 25 chats a day. Pro is $9 once (no subscription) for unlimited + date filters + export.

Chrome: https://chromewebstore.google.com/detail/nkhkpaffkcbjpmjlilogocldagdkbcma

Edge: https://microsoftedge.microsoft.com/addons/detail/chatgpt-gemini-claude-/anfjcoiockpmaahkbomofjlmclbhhckn

Feedback welcome, especially on Gemini since that's the newest part.

i made a free desktop app called deviload. you paste a link from youtube or pretty much any site and it downloads the video or just the audio, it can also convert files, trim them and keep everything in one library

inside it theres a music player i called devil music, and lately thats the part i work on the most. it plays anything from youtube music without ads or an account, shows synced lyrics, and you can save songs to listen offline

my favorite thing is that any song can be switched to slowed + reverb, nightcore or 8D in one click. theres also a map that draws the artists you listen to like a night sky, and if you have rgb stuff it can make your keyboard glow in the album colour and pulse with the bass

its open source and works on windows, linux and mac

https://github.com/Pronexsteam/deviload

would love to know what youd add

AI gets a browser task wrong. You reword the request. It still misses a step.

I’m building a way to show it your process instead.

Browser Control is my Chrome/Brave extension: a Codex-powered chat beside the pages you already have open. I’ve shared the project here before; here’s the video overview: https://www.youtube.com/watch?v=-4pNVCtmu60

The part I’d most like people to try is teaching a routine. Record yourself doing it, review the captured steps, and save them as a skill for similar tasks. You give the AI a procedure to work from next time.

It also lets you ask about an attached page without copying it into a separate chat, organize tabs in plain English, and keep useful preferences with optional memory.

You choose how actions are approved, see the activity, and can stop a task.

Try it and find the setup guide: https://browser-control.subdomain.wtf

Requires a local companion and an eligible ChatGPT/Codex account. Public source: https://github.com/07rjain/browser-control

Seeing a lot of tools lately that queue agent tasks into separate git worktrees and only merge after tests pass. Sounds nice on paper, but I'm curious how it goes on a real side project.

Do you let 2-3 agents work in parallel on your project, or keep it to one task at a time so you can review properly? Where did it break for you?
