FOLLOW YOUR CARDIO FITNESS
View VO₂ max from Apple Health with a compact trend chart. Open it for recorded measurements and age-based reference bands. Past periods show their final recorded measurement. Run reviews include linked or nearby readings with their timestamps.

RECORD HOW IT FELT

A LITTLE ATMOSPHERE
