Short version: WHOOP replaced the 4.0 we reviewed with WHOOP 5.0 and WHOOP MG in May 2025. Battery jumps from about 4–5 days to 14 days, the band is smaller and faster, and the MG adds an FDA-cleared ECG and blood pressure insights. WHOOP is a membership with the band included.

WHOOP is the screenless band that tells you how recovered you are before you decide to crush a workout or take a nap. Here’s what changed, based on launch coverage (we didn’t test it hands-on).
| Spec | WHOOP 4.0 (2021) | WHOOP 5.0 / MG (2025) |
|---|---|---|
| Battery | 4–5 days | 14 days |
| Size and speed | Baseline | 7% smaller, about 60% faster processor |
| ECG | No | FDA-cleared ECG on MG |
| Blood pressure | No | Blood Pressure Insights (beta), MG |
| Membership tiers | One tier | One, Peak and Life (MG) |
Specs from NBC’s WHOOP 5.0 launch report, the WHOOP 5.0/MG listing on Amazon. Checked October 2026.
What matters in real use
- 14-day battery changes everything. You stop thinking about charging.
- Pick the tier you’ll use. ECG and blood pressure features need the MG/Life tier.
- No screen, by design. It’s for data in the app, not notifications.
- Membership pricing. The band comes with a 12-month membership.
Gift it to: the gym regular, the marathon trainer, or the friend who already tracks sleep obsessively.
