Sleep, resting heart rate, HRV, steps and workouts fill in automatically. Got a watch? Great. No watch? The app works exactly the same.
3-day free trial — no commitment, cancel anytime
If you wear a smartwatch, there’s no point retyping what it already measured. With your permission NEXT8 connects to Apple Health (iOS) or Health Connect (Android) and reads only what it needs for readiness and load.
In the morning the app pulls in sleep and resting heart rate and adds the heart-rate curve to your workouts. It never logs anything without you and collects nothing extra. Turn the connection off anytime — and the app keeps working, you just enter things manually.
Real sleep and HRV instead of an estimate.
A workout from your watch into history in one tap, heart rate included.
Without a watch you lose no feature.
You choose what the app may read.
Sleep and heart rate wait, ready to confirm.
The watch recorded it, you just accept it.
Connect NEXT8 to Apple Health or Health Connect and make your readiness more accurate — for free.
