I got tired of posting on r/fitness and getting unclear feedback, so I built an app that analyzes physique photos with AI. It started as a weekend project after I couldn't get good advice on my lifting progress. Upload a few pics and the AI tells you: Where you rank compared to others (using a gaming-style tier system) Scores for each muscle group with actual numbers Body proportions and balance issues Body fat estimates and body type I also added some fun stuff like matching you to a "warrior type" based on your build (turns out I'm built like a Viking, not the Spartan I was hoping…

I spent a month to put together a workout app without writing a single line of code by hand. It's on par with many apps like Fitbod or Fitness AI. Got approved on iOS App Store. Let me know if you want free access, only thing I ask is to give me genuine feedback and one feature you would like to see. I will be asking Codex/Claude to rank the top features and implement it.

Agent Arnold is a gym tracker with a built-in AI coach. Here's how I use it: - "this exercise hurts my shoulder at the end of the movement, remind me proper form and cues" - "how should I modify my workout today based off last week's reps and weights" - `/generate` a bouldering-focused workout routine The app is free, your data is fully exportable (no walled-gardens), and there's an anonymous global leaderboard for motivation, including a "Dishonored" shameboard for anyone caught faking their numbers. I decided to 100% vibe-code this project, a part of it is halluci-coded. I purposely…

I've just launched this little iOS app as an alternative to Apple Fitness, which is cluttered and chaotic when it comes to visualizing basic workout stats and metrics. The idea is to focus on a clean, minimalistic design and only show high-level metrics that are actually useful, e.g. how often did I work out this week/month/year, cardio vs strength vs mobility, surf session count in February, etc. It's free and offline. Also, no signup, no ads, no data sharing, no social feeds, and no notifications. Just open it and get a quick glance at the state of your workout game within 2s.…

i built a heart rate zone training app for runners. ios + apple watch. custom zones, real-time haptics, post-run graphs. all the “smart” stuff you’d expect. but i never talked to a single runner before building it. not even myself lol. started as a thesis → kept building → added features → added a paywall (€4/month!) → launched it → and yeah… no one cared. zero feedback. zero users. just code in the void. i recently made the whole thing free. not trying to “sell” anything now — just seeing if it’s actually useful, and listening this time. curious how others handle this. ever build…

Hello HN, I wanted a simple app to track my fitness progress. Every fitness tracker in the AppStore had too many features for my liking so I made fit-stitch (Free, iOS). It allows you to take snapshots and attach a weight and date to each one. When you've made some progress you can create a before and after picture with a few taps. Hope you find it useful. www.fit-stitch.com

Hi HN, I made a metabolic AI coach to help people with their weight loss and metabolic challenges. In testing with about a dozen people, they have been impressed with how well it figures things out and its surprising insights. I'm surprised, too, at how good it gets compared to typical responses people would ask vanilla chatbots and how positively people are responding to it. https://coach.patchworkfood.com/ Happy to hear feedback or ideas!
