IndexFit scores every lift, run, and recovery day — then puts you head-to-head with friends in weekly fantasy leagues. Train smarter with an AI coach built right into your pocket.
Log your training, watch it turn into points, and battle your friends every single week.
Every set, mile, and recovery metric is scored with the same engine as fantasy sports — diminishing returns, category caps, and PR bonuses keep it fair and impossible to game.
Ask anything, or have it build full strength & running routines tailored to your goals.
One app for the gym and the road. Track lifts, splits, distance, and volume in one place.
Heart rate, calories, sleep, and resting HR sync automatically from your Apple Watch.
Auto-detected PRs across every exercise, with celebrations and bonus points when you hit one.
Drop a TikTok or Instagram workout and let AI turn it into a structured, trackable routine in seconds.
Earn collectible badges for streaks, PRs, and big weeks — and show them off on your profile.
Pick your format, invite friends, and chase the top of the table. Points only go up during the week — so every workout matters.
The all-rounder. Volume, training days, distance, and PRs across both disciplines decide the winner.
The full picture — all 10 categories, including calories, sleep, and resting heart rate.
