Fitness Intelligence Network
A fitness journal with an AI assistant — know your body, move with purpose.
FIN is a fitness journal, not a coaching or optimization app. It logs training, nutrition, sleep, and recovery into one calm, chronological timeline, and surfaces AI insights only when you ask for them — deliberately rejecting streaks, badges, and leaderboards.
Built for fitness-conscious people who want deeper body awareness without competitive game mechanics, and who want the option to share their timeline with a real coach or nutritionist.
Training, nutrition — including AI-powered food-photo analysis — and recovery all feed one connected timeline, with an AI assistant, deliberately never branded as an "AI coach," synthesizing across all three only when asked. FIN integrates with Apple Health and Google Fit, and is currently live in iOS TestFlight beta, with Android coming soon.
