About VO2 Max Pro: Track Fitness Age
Find your Fitness Age: how old your heart and lungs perform, based on your VO2 max from Apple Health. VO2 Max Pro turns the Cardio Fitness readings your Apple Watch already records into a number that's easy to understand, then shows how it's changing and where you stand among people your age. WHAT YOU GET • Fitness Age: see how many years younger (or older) your fitness makes you • Trends: follow your VO2 max over the past week, month, and year • Where you stand: compare with others of your age and sex • Check-In: press the Action button or ask Siri to see your numbers and log a reading, without opening the app • Widgets: your Fitness Age and VO2 max trend on your Home Screen and Lock Screen • Fitness Pass: a shareable card with your Fitness Age, VO2 max, and rank • Lab results: log a VO2 max from a lab or treadmill test and save it to Apple Health • Instant updates: get notified as soon as a new reading arrives WORKS WITH APPLE HEALTH VO2 Max Pro reads your Cardio Fitness, age, and sex from Apple Health, and saves readings you log back to it. Your health data stays on your iPhone. Whether you're training for a race, working on your heart health, or just curious, VO2 Max Pro shows you where your fitness is heading. MAKE IT YOURS Open the Theme Store from Profile to restyle the app. Pick a Look to change Home, your Fitness Pass and your app icon in one tap, or mix backdrops, pass skins, stickers and icons yourself.
