Hey Product Hunt! 👋 We built KinetFit because every fitness app tells you to train harder — none of them tell you where you actually stand. **The idea:** 10 bodyweight tests you do at home → compared against 140 age/gender benchmarks → one number: your Fitness Age. Then an AI coach — running entirely on-device via llama.cpp (Qwen2.5-3B) — builds your training plan around daily recovery. No cloud, no subscription, no data leaving your phone. **What's new in v2.2:** - Training science: 1RM, PR, ACWR load ratio, TDEE - Full workout sessions with auto rest timer - Photo progress album + body measurements - AI food recognition — snap a meal, get calories - Voice coach in 4 languages - Widget + Live Activity **Special launch offer:** Pro is **FREE through August 31**. After that, one-time $4.99 — no subscription, ever. Try the fitness age test and tell us your number! 💪

KinetFit-How old is your body? Find out offline.

Hi Product Hunt!

I'm the solo developer behind KinetFit.

I built it because I was tired of two things: fitness apps that only tell you to "train harder," and health apps that upload every heartbeat to the cloud.

KinetFit flips both. First it asks a different question how old is your body, really? Ten tests give you a single number: your fitness age, plus where you rank among your peers. Then it trains you by recovery, not by a fixed schedule. Retest in a few weeks and watch the number drop.
