The Hammr closed loop
Recovery becomes Readiness, one Adaptive Decision sets today’s macros and volume, you train and eat, then the next night restarts the loop.
Hammr is the fitness app where recovery actually changes what you eat and how you train. Workouts, nutrition, readiness, and progress live in one iPhone + Apple Watch account — not a stack of a lifter, a food logger, and a wearable dashboard.
The loop
- Overnight, Apple Watch or Oura feeds Recovery.
- In the morning, Recovery combines with training load, check-in, and nutrition adherence into Readiness.
- One locked Adaptive Decision sets today’s macro targets and workout volume guidance (Premium).
- You train with volume-scaled prefills and log food toward today’s rings.
- Analytics records the work. Baselines update. Tomorrow restarts.
Five tabs, one account
- Home — daily command center
- Workouts — strength, programs, outdoor GPS
- Nutrition — macros, meals, water
- Analytics — weight, muscle scores, compliance
- Profile — friends, teams, settings, devices
Deep routes (AI Coach, score detail, Apple Health / Oura dashboards) stay inside that account.
Platform
Hammr is iOS only: iPhone plus a standalone Apple Watch app. Android is not supported. GPS is collected only during active outdoor run/walk/hike/cycle sessions, including background while that session is active. GPS is not used for gym workouts.
