• Circular, rectangular, and corner complications
• Latest value and update time at a glance
• Updates after Apple Health saves a newer estimate
• Read-only Health access
• No account or subscription
Just VO₂ Max displays the estimate already stored in Apple Health. It does not measure or calculate VO₂ Max. Apple Health decides when a supported workout produces a new Cardio Fitness estimate.
Your VO₂ Max value, date, and source stay on your devices and are never sent to advertising or analytics providers.
