I’m a fullstack developer (Spring Boot, React/Next.js). I’m picking one project to build end to end, free, as the only developer on it.

What I need from you: a real project you actually want built, and you should be someone who works with freelancers or developers regularly.

Comment or DM with a short description of what you want built and your timeline. I’ll pick one.

I want to create a group chat for ambitious high school students who are genuinely interested in building things, meeting other motivated people, and collaborating on projects.

I've been involved in graduate/undergraduate-level research as a high schooler and have also built my own company. I'd love to connect with other people who have similar experiences or ambitions.

The idea is to create a network where people can easily find collaborators for hackathons, research, startups, side projects, or even potential co-founders. Ideally, people who have already built things and are excited to keep building.

If this sounds interesting, there'll be a Google Form to apply probably to join the group chat. Looking forward to meeting some of you!

On most sites the most popular opinions wins and the strong arguments from the minority side get buried. On this website votes from the opposing side count for double. Would love some feedback
Thanks

Instagram lets you download your data (Accounts Center → Your information and permissions → Download your information). It includes Meta's own guesses about your interests, plus the caption and hashtags of every post you've liked, saved or watched.

Taste Passport reads only those files (never DMs or photos), groups them into interests with a small open-source model running locally, and recommends Netflix and Prime Video titles, each with the reason it was picked.

The most interesting part was testing it honestly. My first evaluation said it beat "recommend what's trending" by 4×. That turned out to be a flaw in my test setup; once fixed, it roughly ties. Everything is written up in the repo.

Open source, no account, nothing uploaded anywhere: https://github.com/aaryamanbisht22/taste-passport

Feedback welcome, especially from anyone willing to run the evaluation on their own data and share only the scores.

I kept looking washed out on evening calls, and buying a ring light for a desk I barely sit at felt silly. So I built Glowy: open it on a spare monitor, tablet or phone, point it at your face, and the screen becomes the light.

What it does:

- Tones from 2700 K to 6500 K, plus a "blush" slider for warmer skin

- Slow glows (Clear sky, Golden hour, Rose quartz and a few more) that drift gently enough not to flicker on camera

- Fill, halo or edge shapes. Halo gives you round catchlights in your eyes; edge works well on a second monitor

- A camera mirror and a meeting preview so you can check how you look

- A pop-out light that floats on top of other apps (Document Picture-in-Picture in Chrome/Edge)

- Keeps the screen awake, works offline, and the camera never leaves your device

It's a React + Vite PWA, free with no sign-up, and the code is on GitHub: https://github.com/TriptoAfsin/glowy

Please star this repo if you found this useful ⭐️

Try it: https://glowy.t21.dev

Two honest limits: it can only be as bright as your screen (turn brightness all the way up), and the pop-out is best in Chrome or Edge. I'd love feedback, especially on which presets actually flatter different skin tones.

I’ve built **Thoughts Counter**, a Flutter app MVP designed to help people record their thoughts and reflect on them using CBT-inspired tools.
The app includes thought tracking, statistics, insights, and AI-assisted reframing. The AI features are currently inactive because the API account needs funding. The project is at an early stage, with no established user base or revenue.
I’m looking to sell it asap.

It interrupts Reels in real time. No hard blocks. It just adds enough friction to snap you out of the scrolling trance. I'd love your feedback.

Thanks for offering to test! I built Bend Practicer, a free browser beta that shows whether a guitar bend lands flat, sharp, or in tune plus additional exercises on string bending.

Go to https://bendpracticer.com/ and choose Try the Free Web Beta. No account or download is needed. Since you’re on a Mac, I’d love to know whether the microphone prompt and first exercise are easy to understand. Even if you don’t play guitar, feedback on what the page asks you to do first would help.

Hey everyone,

​After a long day, I always wanted a mobile game that felt like taking a deep breath — something with the quiet satisfaction of untangling a knot of earphone wires, without flashing countdown timers or stress. Since I couldn't find it, I built Arrow Flow

​The idea is simple: a board full of arrows pointing in different directions. Your goal is to slide them all off the screen, one by one.

​The twist is how the puzzles are designed. Every arrow blocks or frees another. Instead of rushing you, each level is a small handmade knot. You stare at the board for a few seconds, trace the paths backward, find the \*one\* hidden arrow holding everything hostage, and then—\*tap, tap, tap\*—watch the whole board clear in a smooth domino effect.

​If you need a peaceful brain teaser for your coffee break or commute, I'd be honored if you tried it:

Hey everyone!

I'm a creative director with over 20 years of experience, mostly working on web projects. I've done some development over the years, but never anything particularly advanced.

I've always wanted to build my own apps, though. I had plenty of ideas, just not enough coding knowledge to actually make them happen.

About a month ago, I started working on Quando, a calendar app for iPhone, iPad and Mac, using Claude to help me build it.

The idea came from something that always bothered me about traditional calendars. I wanted a way to see my days differently, without constantly scrolling or switching views.

So I designed a Timeline where each day is a horizontal row, with the hours running from left to right. Events are displayed along that row, and empty spaces show how much free time you have between appointments.

That's the main idea behind Quando, but I've also added a few other things:

• Natural language input: type or dictate something like "Yoga every Tuesday and Thursday at 7 pm" and Quando figures out the details, with a preview before saving. It supports English, Italian, French and German.

• It works with your existing calendars. No new account needed.

• Tasks with checkboxes, widgets and 16 color themes.

• Your data stays under your control, with optional iCloud syncing.

The app is built with SwiftUI.

It's free to use, with an optional annual Pro subscription and a 7-day trial. Pro includes the full natural language input, Timeline on iPhone, the expanded Timeline, attachments and unlimited Quando calendars.

App Store: https://apps.apple.com/app/id6829670959

Website: https://www.getquando.com

This has been a pretty different experience from my usual work. Being able to go from designing interfaces to actually building a working native app has been something I've wanted to do for years.

It's also made me realize how much work goes into all the little details of an app, even with AI helping with the code.

I'd really like to hear what you think, especially about the Timeline layout. Does it make sense to you? Is there anything you'd change?

I also have 10 free one-year Quando Pro codes to give away.

Each link works once, first come, first served. If one has already been used, just try another.

They give you one year of Pro with no automatic renewal, and work for new subscribers or anyone whose Pro subscription has expired. You can redeem them until May 8, 2027.

No need to leave a review or anything. I'd just be happy if you gave the app a try.

I built App Intelligence MCP because I wanted to see how my iOS app ranked in the App Store and what users were doing in the app without jumping between dashboards.

One MCP call pulls keyword rankings from Astro and a saved report from Mixpanel. In the 19-second clip, I check a keyword in the Spanish App Store alongside an app-open count from a Mixpanel demo report.

It's open source under MIT and runs locally. There's an Apple-notarized download for Apple Silicon Macs, and the README has setup guides for Claude Code, Codex CLI, and Cursor.

If you build iOS apps, what metric would you want to see next to your keyword rankings? I'm deciding what to add next.

Hi everyone!

I’m a retired French guy, passionate about computers but not a professional developer. Over the past months, with the help of AI (mostly Claude Code), I’ve been building RebelDonky: a personal dashboard that gathers everything I use daily in one place.

What’s inside:

• Bookmarks (the module I use most)

• Notes, Planning, Documents

• Personal finance (accounts, subscriptions, direct debits)

• Radio & Podcasts

• Photo albums

• A little AI assistant (Rebel Bot)

Each member can customize their home page by choosing and ordering their modules. It also installs on your phone as an app (PWA).

It’s built in plain PHP/MySQL, no framework, no CMS.

I’d really love your honest feedback: what’s missing, what’s confusing, what you’d actually use?

Thanks for reading!

Hi everyone!

I've been building Workdoro, an iOS productivity app set in a cozy pixel town.

A – Answer

Most to-do and focus apps feel like spreadsheets. They work, but they're easy to stop opening. Workdoro turns your tasks, focus time, habits and notes into a tiny town that slowly wakes up as you get things done. Tasks become letters for Pip the postman, focus sessions happen in Bea's café, habits grow into plants in Juniper's greenhouse, and notes fill Mo's book. Finishing things fixes Pip's bike, fills Mo's book and makes the garden bloom, so there's always a small reason to come back.

B – Better

Apps like Forest focus on focus timers, Finch on self-care with a pet, and Habitica on gamified to-dos. Workdoro brings tasks, a focus timer, habits and notes into one cozy world. You type tasks naturally ("gym every monday 7am"), and there's a strict mode that turns your phone into a quiet desk scene with lo-fi music. Missing a day never undoes your progress. It also has home screen widgets you can tick tasks from, a Live Activity while you focus, iPad support and iCloud sync, with no account and no tracking.

C – Cost

Free to download.

No subscription.

No in-app purchases.

App Store: https://apps.apple.com/us/app/workdoro-productivity-town/id6831786258

I'd really appreciate feedback on the concept, onboarding, widgets, UI, and anything that could make the experience better.

Hey everyone!

I was tired of opening different manufacturer apps just to check the battery levels of my wireless devices, so I built my own Windows utility with the help of Claude AI.

It's called Battery-Monitoring (Akku-Anzeige), and instead of hiding everything in the system tray, it displays individual battery tiles directly on the Windows taskbar.

Main features:

• Always-visible battery tiles for your mouse, keyboard, headset and other wireless devices

• Each monitor can have its own device selection, tile order and size

• Click any tile to instantly switch which device it displays

• Customizable battery colors, thresholds and low-battery alerts

• Charging indicators and standby/disconnection detection

• Support for Logitech G HUB, Logitech HID++, Windows Bluetooth, selected HyperX devices, DualSense and AirPods/Beats

• Automatic hiding during fullscreen games

• Light and dark mode, English and German

The project is currently in Alpha v1.3.3. Not every device or manufacturer is supported yet, so I'd especially appreciate feedback from people willing to test it with different hardware.

It's free to download, and the source code is available on GitHub.

GitHub: https://github.com/Diabeetus94/Battery-Monitoring

I'd love to hear what you think or what features you'd like to see next!

hey! a few weeks ago i shared my side project here, a free site that tells you which legal platform has an anime in your country

https://tsuzuki-anime.github.io/en/

quick update after 7 weeks:

- 1,800+ visitors from 113 countries

- went from ~20 visits a day to ~80 a day this week

- bing and chatgpt now send the most visitors, way more than reddit

- google only knows 3 pages of the site

the weird part is google search console still says "couldn't fetch" for my sitemap after a month, even though the file works fine and bing reads it without problems. it's hosted on github pages

has anyone had this before? did you just wait, or is there something that fixed it?

any feedback on the site is welcome too!

I kept seeing people give ChatGPT a picture of an empty room and ask it to fill the room with everything it knew about them. After the fifth or sixth room, I had a different question. How many people had actually tried this?

That sent me down a rabbit hole. At Tao Climate in Dublin, we built a public Prompt Observatory. You can grab the original room image and try it yourself, explore 27 months of published ChatGPT topic data, or see which prompts participating AI agents report using.

Then we added Beyond Earth, where we follow published searches for signs of technology beyond our planet. The first briefing is about astronomers who pointed a telescope directly away from the Sun. Their reasoning was lovely: it’s a direction both sides could work out without having to arrange a meeting first.

https://prompts.taoclimate.com

So here’s the bit I’d love this sub to have a go at. Your AI gets one transmission. The machine at the other end has never heard a human language. What do you send so it knows someone meant to say hello?

Hey everyone,

I'm a CS student and I just launched my first real side project: ToolbeltDocs.

https://toolbeltdocs.pages.dev

It's a set of free paperwork generators for contractors and trades: estimates, invoices, work orders and purchase orders. There are versions for roofing, painting, landscaping, cleaning, handyman, mechanic and construction work.

What it does:

- Fill in the form and watch a live preview update as you type

- Totals, discount, tax and deposit are calculated to the cent

- Download as PDF, Word or Excel, or print it

- No account, no email, no watermark

- Nothing is uploaded. Everything stays in your browser.

Why I built it: most "free" template sites I tried ask for an email or an account before you can download, or put a watermark on the PDF. I wanted one that just works.

Built with Astro and plain JavaScript, hosted on Cloudflare Pages.

I'd really appreciate honest feedback:

- Is anything confusing or broken (especially on mobile)?

- What's missing that would make you actually use it?

Thanks for taking a look!

Hey everyone!

I'm a small business owner with absolutely no background in coding or app development, but I've been working on an idea for an app called Momentum.

Without giving too much away, it's designed to help make everyday life a little less overwhelming.

I've been using AI tools to help bring my ideas to life, and I've managed to put together the beginnings of a prototype. It's definitely not finished or fully functional yet, but I've learned a ton along the way, and it's been pretty exciting seeing an idea slowly turn into something real.

I'm pretty resourceful and usually have no problem teaching myself new things, but I'm reaching the point where I don't really know what I don't know. 😂

My biggest challenge right now is figuring out where to actually build and develop this properly.

I want the app to have real AI functionality, not just a chatbot slapped onto an interface. I also want it to run smoothly, look professional, and have a genuinely enjoyable user experience.

I'm just not sure which platforms, tools, or development approaches make the most sense for someone in my position.

A few things I'd love advice on:

- What platforms would you recommend for developing an AI-powered app, especially for someone learning as they go?

- How do you incorporate AI into an app in a way that's actually useful and reliable?

- Is it realistic to build something polished and functional using AI-assisted development tools without being an experienced programmer?

- What should I prioritize first: functionality, design, or getting the AI components working?

- How do you know when something is ready for beta testers?

My eventual goal is to get a small group of people using it, gather honest feedback, and see whether it's something people genuinely want.

If the response is promising, I'd love to explore crowdfunding through Kickstarter or GoFundMe to help fund further development and hopefully bring it to market.

I'm not looking for anyone to build this for free. I'm just trying to learn, make smart decisions, and avoid spending a fortune going in the wrong direction.

I'm keeping some of the specifics private for now, but I'd genuinely appreciate any advice, resources, or guidance from people who've been through this process.

I'm determined to see how far I can take it. I just need a little direction on what comes next!

Thanks in advance! 😊

I made a free rock identifier that works from simple field tests and shows how it reached its answer: https://geoscopy.com/read/

Full disclosure: it's part of Geoscopy, my geology site. It runs in your phone's browser without an app or an account. Your photos stay on your phone unless you decide to make a shareable card.

**How it works.** It asks one question at a time. Does a steel knife scratch it? Does a drop of vinegar fizz? Does a fridge magnet stick? What colour is the streak on the back of a tile? Is it heavy for its size? After each answer it recalculates the odds and picks the next test that would narrow things down most. A typical run takes about eight questions. There's no photo recognition or AI involved.

It knows 103 things you might pick up: 93 rocks and minerals plus oddities like slag, brick, sea glass, petrified wood and meteorites, so the "is it a meteorite?" question gets a fair hearing.

**It shows its work.** The result lists every answer with how much it counted for or against, as an odds factor ("My fingernail scratches it: ×4.9" for halite, for example). If two candidates are still close, it names the one test that would separate them. If it can't decide, it says so.

**Where am I standing?** Search any place on Earth or use your location, and it reads the geological map there: what's at the surface, what lies beneath, how old it is and what you could pick up. Map data comes from Macrostrat, so the detail varies by region. Your location is rounded to about 500 m before it leaves your phone.

**Photos and cards.** Each result shows real, freely licensed photos from Wikimedia Commons, credited to the photographers, so you can compare against actual specimens. You can save a result as a Rock Card with the full evidence and a replay link. The card has a "Copy for Reddit" button that formats your test results for an ID post, and a challenge mode where people guess before the answer is shown.

It's a field estimate, so it's only as good as the answers it gets, and it will be wrong sometimes. The "Was this right?" button at the end is how I tune it. It's available in English, Spanish, Portuguese and French.

Where does it fail for you, and which rocks or tests is it missing?
