Know when to push — and when to rest
A daily readiness score reads your sleep and heart baselines, and a strain score tallies your training volume, active calories and steps against your own 28-day norm. Plus a biological-age estimate and a fitness age from your VO₂max trend — all computed on your phone.
- Readiness score vs your personal baseline
- Daily strain: Light → All-out
- Biological age & fitness age estimates
Heart metrics light up when you bring watch data; everything else works from what you log.
