Description
Stop guessing how hard to train.
Calibrate gives you a daily readiness score in just 3 minutes and tells you exactly how to adjust your workout — so you train smarter, recover better, and improve consistently.
How it works
Each day, Calibrate measures your readiness using:
HRV (from Apple Health) → recovery state
Reaction test → nervous system performance
Quick check-in → energy, stress, soreness
Then turns it into one clear decision:
Push • Train as planned • Adjust • Recover
What you get
Daily readiness score

Smart training adjustments
Your planned session is automatically adjusted:
Reduce intensity when fatigued

Push when primed
Multi-signal analysis
Not just HRV.
Calibrate combines:
