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 real research. Every comparison comes from peer-reviewed studies and official health guidelines (FRIEND registry, WHO, AASM, and more). Tap any metric to see exactly where the numbers come from. Works with your Apple Watch. Wear it consistently, track your sleep, get a workout in, and Vitae handles the rest. Vitae is not a medical device and does not provide medical or diagnostic advice. It's a tool for visualising and understanding your own health data. Always consult a healthcare professional for medical concerns.
