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/

Sector Fit turns every run and walk into a battle for your city. The map is divided into sectors — named places, neighbourhoods, landmarks, and streets. Every kilometre you cover contributes to your group's control over the sectors you pass through. The more your group moves, the more of the city you own. HOW IT WORKS Start a run or walk and your GPS route is tracked in real time. Every sector you cross gets attributed to your group. Leaderboards show which group controls each sector, and groups compete for dominance across the entire map. JOIN A GROUP, DOMINATE THE MAP Create or join a group with friends, teammates, or coworkers. Pool your kilometres to take and hold sectors. Watch rival groups challenge your territory in real time and climb the leaderboard as your group's reach expands. BUILT FOR FAIR PLAY Pace validation prevents impossible speeds from being counted. Daily distance limits keep competition balanced. Anti-fraud checks ensure every kilometre is earned honestly. PRIVACY FIRST Location is only tracked while you are actively recording an activity — never in the background. Sign in with Apple, Google, or Strava, or create an account with email and password. Whether you run every day or take a casual evening walk, every kilometre counts toward your group's territory. Lace up and claim your city.
