I made an app that rates your gym progress with AI

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…

What it does

In the maker’s words, at launch

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 for). The whole thing takes about a minute to run. The natural-or-enhanced detector is still a work in progress, but it's been pretty good on test cases. Would love feedback from HN people. Is this useful? Too weird? Should I add anything else?

    Visualizing Apple Health workout data (stats, trends, insights)Mar 2026 · apps.apple.com · ▲6

    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 trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

  • Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
