WHOOP 5.0 is a significant leap over the 4.0 in every measurable way.

The device is 7% smaller, yet sensors now capture data 26 times per second — up from once per second — while a redesigned processor delivers 10x more power efficiency. That combination enables 14+ days of battery life on a single charge, and pairing the device with the Wireless PowerPack extends runtime to a full month.

WHOOP 5.0 introduces Healthspan with WHOOP Age, a new metric that uses your recovery, sleep, and strain data to calculate how quickly your body is aging relative to your chronological age — and what you can do to slow it. Hormonal Insights give women science-backed, personalized guidance on how menstrual cycles, pregnancy, and perimenopause influence sleep, recovery, and performance.

The full core WHOOP platform carries over: strain tracking, recovery scoring, sleep staging and coaching, Health Monitor, Stress Monitor, and Any-Wear Technology for wearing the sensor anywhere on the body. Three membership tiers — One, Peak, and Life — determine which features unlock, with hardware always included free. Lifetime warranty on all hardware.
