VO2 Max & Cardio Fitness

See your Apple Health VO2 max estimate and cardio fitness trend in a calm, focused dashboard.

VO2 Max Daily Tracker shows:

• Your latest Apple Health estimate • Improving, stable, or declining trend • A personal target range • One-year history • A broad fitness-age estimate with clear methodology • Home Screen and Lock Screen widgets • Apple Watch app and complications • Guidance when no estimate is available

Your fitness data stays on your devices. The app reads Cardio Fitness estimates from Apple Health and never writes Health data.

VO2 max and fitness age are broad estimates for fitness awareness. This app does not diagnose, treat, cure, or prevent any health condition. It is not a substitute for professional medical advice.
