Know whether to push or recover before training. Reps turns sleep, resting heart rate, and strain into a clear readiness score. Eligible new members get 7 days free.
Reps turns your Apple Watch into a recovery coach — no $30/month, no extra band or ring.
Get a daily Recovery score from your HRV, resting heart rate, sleep, and strain — then an AI coach (Rex) that tells you exactly how hard to train today, what to eat, and when to rest.
Smarter than WHOOP without the hardware. Free 3-day trial.
MEET REX — YOUR AI HEALTH COACH
Chat naturally with REX about your health. Ask about yesterday's meals, last week's workouts, or your sleep trends. Choose between three personality modes: Friendly, Normal, or Savage.
