Read full description

Your VO2 Max, tracked the way Apple designed it to be. VO2 Max Tracker turns the fitness data your Apple Watch already collects into clear trends, meaningful milestones, and real motivation — no guesswork, no spreadsheets. WHY VO2 MAX MATTERS VO2 Max is the single best predictor of cardiovascular fitness. Apple Watch estimates it automatically from your outdoor walks and runs — this app shows you what it means and where you're headed. FEATURES • Live VO2 Max trend, fitness level, and percentile for your age and sex • Automatic record detection, with a celebration the moment you hit a personal best • Every workout linked to its exact VO2 Max impact — see which runs actually move the needle • Weight and sleep trends alongside your cardio fitness, all in one place • Smart notifications when you improve, trend down, or hit a streak — capped at once a day, never spammy • Full history and long-term trend charts, not just today's number BUILT FOR APPLE HEALTH Works with the VO2 Max, workout, heart rate, sleep, and weight data already in Apple Health. Nothing to set up beyond granting access once. PRIVATE BY DESIGN Your health data never leaves your device. No account, no cloud sync, no analytics, no ads. VO2 Max Tracker reads from Apple Health locally and stays there — that's the whole architecture. REQUIRES APPLE WATCH VO2 Max readings are generated by Apple Watch during outdoor walks or runs. An iPhone alone cannot produce this data — that's an Apple Health limitation, not ours. VO2 Max Tracker is not a medical device and does not provide medical advice. Consult a professional for health decisions. Terms of Use (EULA): https://www.apple.com/legal/internal/terms-en.html
