FAQ

Frequently Asked Questions

Everything you need to know about fitness rings

What is a fitness ring?

A fitness ring is a wearable health tracker worn on your finger that monitors sleep, heart rate, HRV, body temperature, and activity levels. Unlike smartwatches, fitness rings are lightweight, discreet, and focus on health metrics rather than notifications.

How accurate are fitness rings?

Our lab testing shows that top-tier fitness rings like the Oura Ring Gen3 achieve 94% accuracy in sleep stage detection and medical-grade precision for heart rate and HRV monitoring. We compare all rings against medical-grade devices for validation.

Which fitness ring is best?

Based on our rigorous lab testing, the Oura Ring Gen3 Heritage is our #1 pick for its exceptional accuracy, 7-day battery life, comprehensive health insights, and research-grade sensors. However, the best ring depends on your specific needs and budget.

How long does the battery last?

Most premium fitness rings offer 5-7 days of battery life. Our lab testing confirms the Oura Ring Gen3 consistently delivers 7 days of continuous tracking on a single charge.

Are fitness rings waterproof?

Yes, most fitness rings have water resistance ratings of 5ATM or higher, meaning they're safe for swimming, showering, and daily water exposure. We test water resistance in our lab to verify manufacturer claims.
