Hey Product Hunt, I'm Fernando and I made BicepsMaxx. I've lifted for months and my arms stalled for most of them. When I finally measured, it turned out I'd been doing the same curls every week while my brachialis (the muscle under the biceps that pushes it up) did nothing. Nothing I used told me that. BicepsMaxx does three things: 1. Scan. One flexed photo, about ten seconds. You get an arm score, six zone scores (peak, thickness, brachialis, forearm, symmetry, definition) and a body fat estimate. The scores are AI estimates and the app labels them that way, which is why it also asks you for a weekly tape measurement. 2. Train the weak zone first. Each session opens with two movements for your weakest zone, then a heavy builder and a triceps finisher, because triceps are most of your arm's size. Home or gym, three difficulty levels. The workout player has rest timers and a tempo coach that buzzes on each curl, pause and lower. 3. Rescan weekly. Same pose, same light. Score, zones and centimeters side by side. Also in there: a food scanner with protein targets, Coach Flex (an AI coach that knows your scan and what you ate today), multi-week programs, and it works offline for 30 days once you're signed in. It's built with Expo (one codebase for iOS, Android and web), Convex and RevenueCat with Stripe. For Product Hunt: until we have room, join the beta on TestFlight or Google Play and sign in, and you get a full year of Pro free. First 100 people. https://bicepsmaxx.altuzar.dev/b... I'd really like blunt feedback on the scan. Which zone did it flag, and does that match your mirror?
