your phone verifies.

Every rep counted

Prop your phone up and train. The camera counts each push-up and squat on the phone, never recorded, never uploaded. How it counts.

Honest by design

Proven tasks are marked Verified. Anything the phone can't measure is marked on your word. No fake check-ins. How verification works.

Missed days stay missed

A streak only means something if it can't be rewritten. You get one grace day every 14 days, used on purpose, never automatically.

Your photos stay yours

Weekly progress photos build your before-and-after timelapse, and they never leave your phone.

How a day works

  1. Open Today. Push-ups, squats, a walk and one honor-system habit.
  2. Prop your phone up and go. The camera counts your reps on the phone.
  3. Walk. Your phone's sensors confirm it afterwards.
  4. See what's proven. Verified, on your word, or honor system, always labelled.

See the whole 90-day plan, week by week.
