Just VO2 Max

See your latest Apple Health VO₂ max estimate on your iPhone Home Screen and Apple Watch face. Just VO2 Max puts your value, trend, and last update within easy reach. IPHONE WIDGETS Choose small, medium, or large. Every size shows your latest value, trend, and measurement date and time. The large widget also charts your last measurements. APPLE WATCH COMPLICATIONS Choose circular, rectangular, or corner complications to suit your watch face. The rectangular view includes your trend and last update alongside the value. A CLEAR IPHONE DASHBOARD A focused gauge, a readable trend and date row, and a chart of up to four recent measurements help you follow changes over time. SIMPLE AND PRIVATE • Read-only access to VO₂ max in Apple Health • No account or subscription • Health readings stay on your devices • No ads in widgets, complications, or the Watch app • The free iPhone 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; widget refresh timing is managed by iOS. 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.
