NeuroRest

Know how you slept and how recovered you are, measured against your own normal.

NeuroRest reads the nights your Apple Watch records and turns them into a morning Readiness score, a Sleep score, and a few plain words about how your body is doing. Every number compares you with your own last 60 nights, not with a population average.

DESIGNED FOR SERIES 12 AND ULTRA 4, BUT WORKS WITH ANY APPLE WATCH
Apple Watch Series 12 and Ultra 4 measure heart rate variability all night. NeuroRest is built around that: an overnight HRV curve, night-to-night HRV you can trust, and the full recovery picture. Older watches take a few HRV readings a night. Readiness, sleep, heart rate, Overnight Vitals and Daytime Balance all still work; a handful of HRV views need the newer watch, and the app tells you which.

READINESS
Each morning, from your sleeping heart rate, your lowest heart rate and your overnight HRV, each against your last 60 nights. Choose what drives it: Balanced, HRV-led or Heart-rate-led.

SLEEP
How long and how soundly you slept, against your own nights. Stages, time awake, wake-ups, and heart rate and HRV through the night.

OVERNIGHT VITALS
Sleeping heart rate, HRV, wrist temperature, breathing rate and breathing disturbances, each against your own range. When several are off at once the night reads Strained, and NeuroRest lets you know.

RECOVERY TREND
One line, one word: Run down, Fair, Solid, Strong or Prime. Your last three weeks of HRV and lowest heart rate against your own past year, so real progress stays visible for months. Swipe back through it, and see where you were three months ago.

DAYTIME BALANCE
Stress, restorative and active minutes across your day, from your watch's heart rate and motion.

HABITS
Tag alcohol, late meals, workouts, travel and anything else. NeuroRest shows what each one does to your next morning, and how confident it is.

MINDFUL SESSIONS
A breathing pacer, with your heart rate and HRV during the session and how they compare with before.

REPORTS
A monthly report, a weekly summary, a PDF to share with your clinician, and a full export of your data.

BEDTIME
A wind-down reminder built from the time you actually go to bed.

FREE, PRIVATE, NO ACCOUNT
No subscription, no ads, no in-app purchases, no tracking. Your health data stays on your iPhone. Tags and settings can sync through your own private iCloud, which only you can see.

WHAT YOU NEED
An iPhone and an Apple Watch worn to bed, with Sleep tracking turned on in the Health app. Scores start after 14 nights and settle by 30; NeuroRest can use the nights your watch has already recorded.
