Oura Ring 4 vs WHOOP 5.0: which one should you buy?
The Oura Ring 4 and WHOOP 5.0 are the two best-known screenless health trackers. Neither shows the time or notifications: they measure you 24/7 and show everything in an app. Both also depend on a membership. The main differences are the form factor (a ring vs a band), how you pay, and whether your focus is sleep and everyday health or training and recovery.
Quick verdict
Oura Ring 4
Choose the Oura Ring 4 if you want the most discreet tracker, mainly care about sleep and everyday health, and prefer a small monthly fee.

Ring or band
The Oura Ring 4 is an all-titanium ring you can wear with anything, including formal clothes, and it doesn't get in the way at the gym. You must use Oura's sizing kit before buying, because Oura sizes differ from regular ring sizes. WHOOP 5.0 is a soft band on the wrist or arm; it's less discreet but has no sizing issue and can be charged on the body with its wireless PowerPack.
Sleep and health vs. training and recovery
Oura tracks more than 50 health metrics and is strongest on sleep, daily readiness, stress and women's health. WHOOP measures heart rate every second and is built around Strain and Recovery, telling you how hard to train each day, plus VO2 max, a real-time stress monitor and Healthspan, which estimates your WHOOP Age and Pace of Aging.
How you pay
Both need a membership for the full experience. Oura includes the first month and then costs $5.99 per month. This WHOOP listing includes a 12-month membership with the device, which you renew afterwards to keep using it. Compare the total cost for the time you plan to use it before you decide.
