Your VO₂ max, wherever you look first. Just VO2 Max brings your latest Apple Health estimate to three equally important places: your Apple Watch face, iPhone Home Screen, and iPhone Lock Screen. Check your value without opening an app. ON YOUR WATCH FACE Choose a circular, rectangular, or corner complication. The rectangular style also shows your trend and measurement date and time. ON YOUR HOME SCREEN Choose a small, medium, or large widget. Each shows your value, trend, and measurement date and time. The large widget adds a chart of up to six recent readings. ON YOUR LOCK SCREEN Choose a circular gauge or rectangular widget. The rectangular style shows your value, measurement date and time, and trend when available. COMPANION APPS Use the iPhone and Apple Watch apps to grant read-only Health access and view the latest reading. The Watch app updates when opened. The iPhone app also shows up to six recent readings, with controls to refresh and check setup. The iPhone dashboard adapts to iPhone Duo’s closed and unfolded displays, in portrait and landscape. SIMPLE AND PRIVATE • Free, with no account or subscription • Read-only access to VO₂ max in Apple Health • Health readings stay on your devices • No ads in widgets, complications, or the Watch app • The iPhone companion app is supported by banner ads Just VO2 Max displays estimates already stored in Apple Health. It does not measure or calculate VO₂ max. New readings depend on Apple Health and supported workouts; iOS and watchOS manage refresh timing. The trend compares your latest estimate with up to three previous readings. Your VO₂ max values, sample dates, and sources are never sent to advertising or analytics providers. The app displays fitness information only and does not provide medical advice.
