What it is
Four scores and a paragraph, every morning.
Vital reads 25 Apple Health signals (HRV, sleep, training, nutrition, cycle, mood) and writes you a paragraph covering recovery, exertion, stress and health.

Readiness
80 PRIMED
The verdict: push today or back off, from recovery, training balance and trend.
Recovery
93 /100
How rebuilt you are overnight: HRV against your own baseline, sleep quality, resting heart rate.
Exertion
1.7 /10
Training load from continuous heart-rate zones, not step counts.
Health
62 /100
The long view: activity, sleep, nutrition, hydration and stress as one composite.
Real values from the morning in the screenshot above. Stress is scored separately, 0 to 100; a quiet day reads low.
AI insights from your actual data.
Vital's AI reads your morning (HRV, training load, sleep debt) and writes a paragraph about what's going on. Written for your day, not pulled from a template. Part of Vital AI.
Private by default.
EU servers, encrypted. One tap deletes everything, and we don't sell your data.
Native iOS, no extra hardware.
Apple Watch is optional. No Whoop strap to charge, no Oura ring to lose down the side of the sofa. If you've got an iPhone, you're set.
The science is public.
Every weight in the scoring algorithm traces back to peer-reviewed research, around 40 papers across HRV, sleep and training load. Read the science.
No strap, no ring, no monthly hardware fee.
Whoop locks you into a band. Most rivals need an Apple Watch on your wrist all night. Vital works from what your iPhone already has. See how it compares to Whoop, Athlytic and Bevel.
Who it's for
You already track HRV.
You train deliberately, and you're tired of apps that explain what a calorie is.
