About WITU Ring

How is the ring different from the WITU bracelet?

The ring uses optical PPG sensors and is ideal for sleep, HRV and background monitoring. The bracelet adds clinical-grade dual ECG. Many people wear both: the ring at night, the bracelet by day.

How do I find my size?

Order a free sizing kit. We recommend wearing the sizing ring for 2–3 days, since fingers change in volume throughout the day.

Do I need a subscription?

No. Basic sleep and HRV monitoring works without a subscription. Advanced analytics and AI recommendations come with a Premium subscription, but that's optional.

Can I wear it in the shower and pool?

Yes, the ring is water-resistant. There's no need to take it off for water.

Ready to start?

Basic monitoring — no subscription. The app works for free with any WITU device.
