WHOOP 5.0

Armbandreleased 2025MyBodyAI · No integration yet

WHOOP 5.0 is an armband from 2025, sitting in the premium band. The maker does not publish a list price for it.

It reads 16 of the 33 signals this comparison tracks. Nothing at all from body composition. Rarer readings it does take: sleep efficiency.

By sensor class: 5 at high accuracy and 4 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor, an optical blood oxygen sensor, a skin temperature sensor and an accelerometer. Blood oxygen is measured through the night, not continuously through the day.

Its 14 days per charge are the longest of the 11 devices of its kind here that publish a figure. Rated IP68 / 10m, fine for swimming. It weighs 26.5 g. A WHOOP membership subscription is required to use it.

Screenless strap, subscription (One/Peak). Adds steps/VO2max/WHOOP Age vs 4.0; no ECG/BP (MG-only).

Turn a supported wearable into daily health scores

MyBodyAI reads Fitbit, Oura, Polar and Withings by logging in, and Garmin from a data export, then builds daily recovery, sleep, load and immune scores, a biological age estimate, and early warnings. Optional, and separate from this comparison.
