WHOOP MG review

Read the full review

If you want long battery life, excellent sleep tracking and an app you'll actually enjoy, the MG gets those right. If you lift a lot or don't want an ongoing membership, it's a hard sell.

Love it

Meh

  • About two weeks per charge
  • Charges while you wear it
  • Excellent app
  • Precise sleep tracking
  • Comfortable and quick-drying band
  • Struggles with strength workouts
  • ECG can take a few tries
  • Clasp can detach
  • Stops working without a membership
  • ECG and HRV don't reach Apple Health

Where it shines

  1. Heart rhythm checks

    It provides ECG readings at home through its heart-screening capability.

  2. Recovery

    Recovery and readiness are analysed day and night alongside its health features.

  3. Sleep

    Your night is split into time in light, REM and deep sleep.
