I've spent the past year building what I believe to be a highly comprehensive investment research and tracking platform . As an avid investor who incorporates a few strategies for investing (index investing, factor tilts, some quality stocks at good valuations, a bit of dividends), I was continuously jumping between different websites and tools for different needs, most of which were missing the exact thing I needed. I wanted one place which had visual representation of stock fundamentals wit...

Hi travellers, I'm a traveller myself that everytime a want a new destination I get into the same problem. Basically, hopefully not only myself, I have a lot of saved videos on tiktok/reels or even youtube with destinations, attractions etc and beside this a lot of other crap and I lose a lot of time just searching for these videos and sorting them. Now I'm a solo developer too and I got an idea, I thought to create a mobile app and while scrolling on different platforms instead of you saving th...

Hey everyone. I'm building an app called Merios and I'd love an honest gut check from this sub before I push it further. Quick version of what it does: you upload your bloodwork (any lab PDF, or even a photo of a printout), and it reads every marker for you against optimal ranges, not just the "in range / out of range" your doctor hands you. Then it pulls in your wearable data (Apple Watch, Oura, Garmin, Whoop) and how you've actually been feeling day to day, and tries to line all th...

My wife is on an iPhone, I'm on a Galaxy. We kept losing track of household stuff — who's buying what, whose turn it is, when a bill is due. We tried the obvious things: - Todoist / TickTick: great apps, but sharing is a workspace feature layered on top of a personal to-do app. Felt like using a project management tool to ask someone to buy milk. - Notion: we both stopped opening it within a week. - Apple Reminders: my Galaxy doesn't exist as far as it's concerned. The specific thing I w...

Every developer has code they'll probably never touch again. The half-finished CLI from a weekend. The tutorial project that stopped halfway through. That weird experiment that actually taught you something. The utility script that's ugly but gets the job done. Most of that code just sits on a hard drive until it's forgotten. I started The Open CodeYard, a GitHub repository for unfinished, experimental, and abandoned projects that are still worth preserving. Not because they're perfect, bu...

Curious what made the difference for people who actually shipped something versus the projects that quietly died after a few weeks. Was it a specific habit, a deadline, having someone else involved, or something else entirely? And what's a side project you gave up on that you still think about?

Hey everyone! Building a SaaS is hard, but getting honest feedback is even harder. So I thought it'd be cool if we helped each other out. Drop your SaaS in the comments and include: • What your product does • Who it's for • One thing you'd like honest feedback on I'll personally review as many as I can and leave constructive feedback. If you share your project, please take a few minutes to review someone else's too. Let's help each other build better products. submit...

I made this little thing when I was bored...It quietly shows a handful of real aircraft passing near you and of course with time and weather. It’s not very useful tho. https://github.com/jasonlx327/passing-sky

I'm not even sure how to explain this properly but I'll try. Built something for months completely alone. No team, no co-founder, nobody to reality check anything. Just me and whatever made sense in my head. Thought I understood the product deeply. Knew every corner of it. Could explain any decision I made and why. Put it in front of people last week for the first time. First guy spent maybe 90 seconds on it then pointed at a feature I had hidden three levels deep because I thought it wa...

Hi Reddit, A few years ago, I published an app that let you play laser tag in real life. Back then, the targeting was a bit shabby because of the limited performance of vision models, so I opted for a gyroscope + location only approach. It was good enough but it had a few serious accuracy limitations that didn't make the game as enjoyable. Also, Flutter GPU and Impeller were still a very new work in progress, so the game was more 2D objects moving on the screen with perspective tricks instead...

Side project I've been putting a lot of hours into: Ping, an Android app where phones talk directly to each other over Bluetooth — chat, GPS location, photos, even SOS broadcasts — with no Wi-Fi, no cellular, no backend server anywhere. Every phone running the app acts as a relay, so a message can hop through several other people's phones to reach someone who isn't even in range of the original sender. Started it because I kept thinking about how fragile "communication" actually is the...

TL;DR https://vylite.app . Vylite is the desktop continuation of Meros, the notes app I shared here in this subreddit 8 months ago. I've spent those 8 months rebuilding it four times, and iterating on each rebuild a dozen times, and this is where it landed. It's inspired by the terminal: minimal, instant, one thing at a time. It opens to a single input line. Notes are local plain markdown files on your device. There is zero telemetry, no user analytics, no server, and notes are ...

Yesterday I posted my first app here, a screenshot tool. The kind of app that hooks the mouse and types into your windows. So you can imagine my morning when my computer started typing BY ITSELF. Spaces pouring into the chat box, screenshots firing that I never took, my dictation app choking. For an app like mine, "it types on its own" is the scariest bug that exists. I'd just put a download link on the internet. So we went full forensics mode, me and the AI I built the app with: K...

My husband and I built a book tracking app to address all the things I’ve ever wanted out of goodreads. Chiefly, a virtual shelf with actual spines that looks like my bookshelves at home. As shown in the video, you can drag books around, lay them flat, face them out, add decor, etc. Test flight: https://testflight.apple.com/join/nAgk2SDN Play store: https://play.google.com/store/apps/details?id=com.fisherbirdsoftware.shelflife I don’t think a large public database of spines exists so I...

After seeing a voxel experiment on X, I had this random idea: what if I could build a Zoo Tycoon style game, but set across floating islands, each with its own biome and animals? This is just a very early, completely random prototype made in a few prompts. I think it’s going to be incredibly cool when, in a few years, anyone can create the exact game they have in mind just by describing it.

Hey everyone, I’m a solo founder from Georgia, and today I launched Azrivo on Uneed. I started building it because I kept running into the same problem with AI assistants: one model would often accept the way I framed a question and return one confident answer, even when the decision needed opposing viewpoints. Azrivo gives you four ways to work with AI: Ask one specialist directly Compare several specialists in Panel mode Have opposing specialists debate and produce a verdict Gi...

I spent months building my first app. In my head I imagined friends asking for updates, people trying the beta, lots of feedback. Reality: I sent out TestFlight. Three people downloaded it. None of them came back. It wasn’t devastating, just frustrating. It made me realise that building the product is only half the job. Getting people to care is a completely different skill. Curious if anyone else’s first launch was equally underwhelming. And any indie dev hacks you guys could shar...

It was totally useless before, now its only slightly useless. Now some ghosts appear as you browse around. On PC, use W-A-S-D keys, SPACE, SHIFT and mouse to explore. On mobile, you will have instructions on screen. https://anshs.github.io/matrix-rain/

The main parts are an ESP32 attached to a hall sensor, which I positioned close to the wheel. Using a magnet attached to the back of the wheel, this tells the ESP32 when a full rotation has completed. It gives a timestamp (and total distance) to each magnet-pass, which is stored on the network. A python script (on my laptop) then retrieves this data in the morning, turns it into a .FIT file, and uploads it to Strava through the Strava API (with a randomly chosen run title, taken from a mostly AI...

For many developers, the AI workflow looks something like this: write a prompt, get a response, copy what's useful, and move on. This covers a surprising range of tasks, from summarizing a document to
