I made ColorGuessr , a small iOS game where you try to find a target color on a color wheel. The closer you get, the more points you score. I shared an early version here a while ago and got a lot of useful feedback, so a big thank you for all of you! Since then I’ve added: New game modes Name That Color , where you guess the color based on its name Blitz , faster rounds with streak boosts Live multiplayer with friends and random players Public leaderboards New menu a...

One year ago I was searching for a simple invoice generating tool, since I didn't have that many invoices I didn't need a big tool, just something simple, free and with no ads and I couldn't find one at the time, so I built one. I was using it for myself but then I decided to share it on the internet and after one year it is getting 1k monthly users who are generating invoices. Since it started getting users I have made some changes since launch and also added some features requested by users. ...

Hey everyone, I started building a simple ML portfolio project. The idea was to analyze Google Play Store reviews, run sentiment analysis, build a dashboard, and move on. After going through 10,000+ reviews, I noticed something unexpected. The same complaints kept showing up everywhere: Crashes Bugs Performance issues Reliability problems What got my attention wasn't the complaints themselves. It was how hard it was to make sense of all that feedback and identify what act...

I'm a solo founder and recently launched Scubamail , an email marketing platform focused on startups, creators, and small businesses. The product is live, emails are sending, automation works, and I've started onboarding a few early users. Now I'm facing a challenge that many founders probably know well: How do you get the first 100 beta users when nobody knows you exist? So far I've been: Posting on Reddit and Indie Hackers Reaching out to founders directly Sharing progress pub...

Watched an interview today with a 21-year-old leaving Oxford (Lincoln College, maths) to focus full-time on an AI startup. The interview is the dropout story, but the bit that matters for this sub is the moment of commitment. He talks about the inflection point where the thing you're working on stops fitting around the rest of your life. Not because it's getting bigger, but because the world is moving fast enough that part-time effort means you miss the window. He frames the dropout not as &...

This is just so incredible... I honestly never thought this was possible for me. But I did the thing... I JUST STARTED! I put together a working MVP. Just the bare minimum functionality. Bought a domain and put it out there. I posted about it here on Reddit and got in contact with the people who commented and started using it. I followed a simple concept that just came to me naturally: put out what you have post about it listen to feedback in the comments implement the feedback a...

Choosing a stock API looks simple until the project becomes real. At first, you only need a few prices. You send a request, get JSON back, load it into pandas, and move on. But the moment that API sta

PDF files contain more information than what appears on the page. Behind every PDF document is metadata that stores information such as the document title, author, subject, keywords, creator applicati

This started as a personal project. I was constantly misplacing my AirPods, smartwatch, and other Bluetooth devices around the house. I'd spend way too much time walking around trying to figure out where they were. I tried a few Bluetooth finder apps, but none worked quite the way I wanted, so I decided to build my own. The app scans for nearby Bluetooth devices and uses signal strength to help determine whether you're getting closer to or farther from a device. Over time I kept adding fea...

I did this a few days ago with startup URLs and got way more replies than expected. Now I improved the report and it also works with ICPs. Drop your: - startup URL - app idea - ICP - niche - or problem you want to solve I’ll check if Reddit already has people talking about that problem, asking for tools, or showing buying intent. I’ll reply with a short public summary. If there’s enough signal, I’ll create a private report link with the full breakdown. submitted by &#32...

I’m making Type for Speed , a PS1-style racing game where your WPM controls the car. Every correct word gives you speed, every typo kills your momentum, and holding W does absolutely nothing. Steam: https://store.steampowered.com/app/3458270/Type_for_Speed/ Feedback is welcome

Drop your side project below. I'll pay for 3 real users to test it and send you the recordings. I run a crowdtesting platform and I need case studies. So here's the deal: drop your app link in the comments and I'll set up a free test campaign for the first 10 people who respond. You get 3 real testers using your app for the first time, screen recordings of every session (or written feedback if you'd rather), and an AI-scored UX report. I've done this for about 40 projects now. Every single...

i built a finance-related app a while back mostly to learn but haven’t pushed an update in months. i recently checked some of its metrics and noticed that it is still getting new users pretty much everyday and its core functionality is still being used. i just wanted some guidance since i am not really in the app development space. was i really onto something that people want? and more importantly, should i continue development? [link] &#32...

Quick bit of background. I am a CS student and I have been building apps since high school, back in the pre ChatGPT days. Nothing big, just some basic stuff. It started during Covid when I suddenly had way too much time on my hands, and I always dreamed of having my own app on the Play Store. It took me a couple of months and the final product was honestly kind of bad, but I did not care at all. I was just so proud that I had built something new with nothing but my laptop (and Stack Overflow obv...

A while ago I started a project to help me keep track of my wife’s wishlist, so that whenever her birthday or our anniversary rolls around, I could pull it out, see what she’s been talking about, and avoid analysis paralysis. Originally, it was just a tiny mini-site to help me track the ideas and play around with some UI layouts. But right in the middle of tinkering with it, I unfortunately got laid off from my job. Instead of letting the job-search anxiety and doom-scrolling take over, I deci...

I track a lot of shows, and I wanted an app that was genuinely beautiful and didn't lock things behind a paywall or bury them in ads, so I built this and named it StillWatching. Some bits I'm happy with: you can filter shows by streaming platform, find movie tickets straight from a film's page, react to episodes with GIFs, and there's a Home Screen widget for whatever you're up next on. Discover by decade and genre too. Honestly part of what pushed me here was that my old tracker (TV Time, w...

GitHub: https://github.com/Christian-Katzmann/app-it I build a lot of small AI-assisted projects, and after a while I realized I was spending more time remembering how to launch them than actually using them. Every project had its own ritual: npm install npm run dev open localhost remember which folder it lived in So I built /app-it. It turns local projects into clickable dock apps, so they feel like normal applications on your machine. Click the icon and it launches. It'...

i have been working on this platform for the past 3 months. A free platform where founders can exchange feedback systematically without any algos controlling anything. If you give feedback to someone, you go up in the queue, if you don't and just want to get feedback without helping the community you'll go down in the queue and even can't see your feedback unless you gave back give and get, that's all we have been working hard, really really hard and for free just to get this working. it's...

My dad is the reason I ever touched a computer - 'Prince of Persia' on a CRT monitor at his office, thirty-five years ago. Now I build interfaces for a living, and he still calls me when ads pop up on his phone. When I moved from Romania to Spain, I wanted to keep one thing going: our chess games. Chess.com felt too complex for him, so I built something simpler. One link, he clicks it, we play. No account, no onboarding. I sent him the link on WhatsApp in April. His reply: "I went to th...

so i made a little tool that generates meal plans based on whatever you have in your fridge. built it with a no-code thing over a few months, its free right now and somehow has like 500 people using it monthly which blew my mind. a bunch of them have emailed asking for more features (saving plans, grocery lists) and id happily build a 5/mo paid version, the problem is i have no idea how to actually do the payment + accounts + "this person paid so unlock the thing" side of it. I've ...

solo dev here. noticed a pattern where founders keep saying the same thing , they find out a competitor changed their pricing or launched a new feature when a customer mentions it on a call. by then it's already too late. so i built a tool to fix that. you add competitor URLs (pricing page, features page, changelog), it scrapes them every night, and if something real changed it emails you a plain english summary of what changed and why it might matter. not just "something changed on this ...

The FIFA World Cup 2026 starts in 5 days! ⚽🏆 Don't know where to watch it? I built a free tool that auto-detects your country and tells you the exact official TV channels and streaming apps. Find your stream here 👇 https://worldcup.techfliq.com/ #WorldCup2026 #FIFAWorldCup #Football

Free on android, free to scan 3 products each day + 3 earnable scans, so total 6. Simply open the app, answer a few questions regarding yourself (your goals, diet, and allergies), and start scanning packaged food. It gives you the entire detail about that product, with ingredients list, allergens, dietary restrictions for you, with giving the product a score from 0 to 10 based on YOUR health profile, so you can decide what to eat, and what's really good for you. Try it out, let me know what yo...

Few weeks ago I posted asking what makers waste the most time diagnosing on their printers. I read every reply and built from those answers. Nozzy is 90% done — an AI companion for 3D printers: - watches your webcam and stops failures before they eat your whole spool - diagnoses a failed prin t from a photo and walks you through the exact fix - knows your specific printer (Bambu, Klipper, Prusa) — every answer is tailored to your machine - has a hand-drawn character with 56 ex...

Hey everyone, I’ve had a dinosaur hyperfixation for a while and kept looking for a simple interactive map of where dinosaur fossils have actually been found. I couldn’t really find the version I wanted, so I started building one. The main map is here: https://thefossilatlas.com/map It maps selected dinosaur fossil discovery locations and connects them to dinosaur pages, fossil formations, country guides, and source/caveat notes. One important note: the pins show modern fossil discovery...

Hello everyone, Every converter I found wanted me to upload the file to their server first, so I ended up building my own. Runs entirely in the browser, nothing gets uploaded. https://markdone.dev Does md, word and readme files to pdf + json <-> toon for the ones that need to watch their limits. Still new so there's probably some rough edges, lmk if something breaks.

I’ve always enjoyed idle RPG and auto battler games. I’ve spent quite a lot of time in different projects in this genre because they don’t require much time or attention. You can log in for a few minutes, get some progress, and then get back to your other tasks. A few months ago, I started thinking about what kind of pet project I could build for myself, and I decided to try creating my own idle RPG in Telegram. At first, it seemed to me that these games were quite simple. Characters automatic...

I have been building a tool on the side for a few months. Started getting paying users last month and realized I was running real revenue through my personal bank account with zero business structure behind it Kept putting off making it official because I thought it would be this whole thing. Paperwork, government sites, bank applications, weeks of waiting and thats what everyone told me to expect Ended up asking Claude to handle all of it in one conversation. Picked the right structure for m...
