Consistency,
gamified.

Momentum OS is a workout tracker, calorie counter and macro tracker that turns showing up into a game — streaks, XP, ranks and an AI coach that learns your metabolism. Keep the momentum, get the results.

Everything that keeps you showing up

Momentum, not willpower

Every 20+ XP day keeps your momentum alive. Earn shields, climb levels, and watch consistency compound — Duolingo-style, but for your body.

Muscle-level heat map

A real anatomical figure — male and female — shows exactly which muscle heads you're hitting and which you're neglecting, down to rear delts vs lateral delts.

Nutrition that adapts

Adaptive expenditure learns your metabolism from your weigh-ins and intake, then updates your calorie and macro targets every week. Barcode scanner, AI photo logging, 32 micronutrients.

Weekly Progress AI Analysis

Drop in your weekly progress photos and the AI reads your week-over-week change against your goal — leaner, fuller, or holding — then tells you exactly what to adjust. Part of AI Coach & Elite.

AI Coach

An AI coach that knows you

Weekly optimization across training, nutrition and recovery — grounded in your actual volume, biometrics and trend weight. Ask it anything, unlimited.

Programs for your goal

Glute & hamstring builders, upper-body splits, strength bases — or let AI design a plan around your goal, schedule and equipment. Share yours to the community and build a following.

Compete & rank up

Weekly XP leagues with friends and the world. Test your bench, squat, deadlift and mile to earn a rank from Iron to Elite.

New

Challenges

Join global challenges from Momentum OS or your favorite creator's #hashtag challenge — live leaderboards, streak-based scoring, and prizes from the host. Pro members launch private challenges with friends.

New

Accountability partner

Pair with a friend and see each other's daily check-in — one tap sends a nudge when they're slipping. Consistency is easier when someone's watching.
