## Description

See your Apple Health VO2 max estimate, cardio fitness trend, fitness age, widgets, and Apple Watch complications. Private and local-first.

See your Apple Health VO2 max estimate and cardio fitness trend in a calm, focused dashboard.

VO2 Max Daily Tracker shows:

• Your latest Apple Health estimate
• Improving, stable, or declining trend
• A personal target range
• One-year history
• A broad fitness-age estimate with clear methodology
• Home Screen and Lock Screen widgets
• Apple Watch app and complications
• Guidance when no estimate is available

Your fitness data stays on your devices. The app reads Cardio Fitness estimates from Apple Health and never writes Health data.

VO2 max and fitness age are broad estimates for fitness awareness. This app does not diagnose, treat, cure, or prevent any health condition. It is not a substitute for professional medical advice.

VO2+ is optional. Choose a monthly plan, a yearly plan, or a one-time lifetime purchase. Monthly and yearly plans include a 7-day free trial for eligible new subscribers. Prices are shown in the app before you buy and vary by region. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Your account is charged for renewal within 24 hours before the current period ends. Manage or cancel subscriptions in Apple Account settings.
