WEEKLY CHECK-INS
Answer your coach's questions, log body measurements, upload progress photos, and submit your weekly check-in in minutes — not hours.

MACRO TRACKING
Log calories, protein, carbs, fat, and fiber per day with totals against your prescribed targets. Connect MyFitnessPal, Cronometer, or MacrosFirst to skip manual entry entirely.

HABITS
Check off daily habits and see your weekly streak in a single glance. Optional 7 PM push reminder if anything's still unchecked.

COACH COMMUNICATION
Message your coach back-and-forth, see when they've read your messages, and review their feedback the moment they post it.

WEARABLES + NUTRITION APPS
Connect Garmin, Oura, Fitbit, Whoop, Coros, Polar, Suunto, Withings, MyFitnessPal, Cronometer, or MacrosFirst — activity, sleep, weight, and nutrition flow into your check-ins automatically.

PRIVACY FIRST
