VO₂ Max shows how much oxygen your body can absorb at peak effort. The redesigned dashboard puts the latest measurement, rolling averages, and your personal best in one view so you immediately see how training affects cardio fitness. ESTIMATES FOR RUN & BIKE - New tab turns VO₂ max + weight + power into W/kg and FTP estimates for running and cycling. - Compare modeled race times and power against your actual HealthKit FTP/power. NEW DASHBOARD - Trend cards highlight the 7-day average, any selected range, and your best value with percentage deltas. - The interactive chart responds to 1W, 2W, 1M, 3M, 1Y, or All filters and animates every new HealthKit reading. - Entry tiles list the test type, source, and timestamp so you can compare prediction and max-exercise tests. INSIGHTS & GUIDANCE - The info sheet matches your value with the correct age and sex bracket to explain whether it is poor, good, or superior. - Manual refresh, HealthKit warnings, and empty states keep permissions and sync issues obvious. - Trial countdown and subscription access stay a tap away. APPLE WATCH + WIDGETS - All complication families are supported, so your latest VO₂ max is available on every watch face. - iPhone Home Screen and Lock Screen widgets follow the dashboard range you selected. - The Widget Showcase walks you through pinning widgets or complications and previewing layouts. HOW VO₂ MAX IS CAPTURED 1. Wear Apple Watch for at least 24 hours, then record several Outdoor Walk, Outdoor Run, or Hiking workouts with heart rate and GPS. 2. Apple may need several qualifying workouts and passive measurements before the first VO₂ max estimate appears. 3. Give this app read access to Cardio Fitness (VO₂ Max) in Apple Health so the dashboard, widgets, and complications can display the data. Requires Apple Watch Series 3 or later. VO₂ Max makes it easy to see if your cardio fitness plan is working today, over the last weeks, and all time. Terms and conditions: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
