Vitae.

Your Apple Watch knows more about you than you think. Vitae turns all that data — VO₂ max, resting heart rate, HRV, sleep, recovery, daily movement — into one number you'll actually understand: your health age. Some weeks you'll be younger than your years. Some weeks you won't. Either way, you'll know exactly why. What you get every week: • Your health age, calculated from 9 key metrics • What's helping you, ranked • What's holding you back, ranked • Trends so you can see real progress Built on
