What Whoop gives you
- A screenless band worn all the time, including in sleep.
- Recovery, strain and sleep scores built on heart rate and HRV.
- Coaching and trends in the Whoop app, on a membership.
What Apple Watch already records
- All-day heart rate in the background.
- HRV, resting and walking heart rate.
- Sleep stages and the Vitals app overnight.
- Workouts, Activity rings and training load.
Apple Watch writes all of this to Apple Health, where other apps can read it.
A gap worth knowing
Whoop exports heart rate to Apple Health during activities such as sleep and workouts, plus a daily resting heart rate, but not continuous waking-day heart rate. So apps that read your whole day from Apple Health see gaps with Whoop data. Apple Watch fills those gaps. See which smartwatches work with Apple Health.
Whoop alternative Apple Watch apps
| Whoop feature | On Apple Watch |
|---|---|
| Recovery score | Third-party HRV and readiness apps |
| Sleep tracking | Built-in Sleep and Vitals |
| Strain | Training load in the Fitness app |
| What stressed you during the day | 70 BPM: heart rate against your calendar |
Where 70 BPM fits
70 BPM does not give a recovery score. It answers a question Whoop's scores do not: which meeting, commute or evening raised your heart rate. It reads Apple Watch heart rate from Apple Health and shows it behind your calendar events. Free, no account, no membership, nothing uploaded.
