Ray vs. Amazfit Helio Ring
A $149.99 ring built to pair with Amazfit watches, compared with a standalone band.
The Amazfit Helio Ring is a $149.99 smart ring with no subscription. It adds blood-oxygen and stress (EDA) sensing and is designed to work alongside an Amazfit watch in the Zepp app. It lasts about four days per charge. Ray is meant to be your only wearable, worn on the wrist and powered by light.

The short answer
Choose the Helio Ring if you already wear an Amazfit watch or want an affordable ring. Choose Ray if you want one tracker that stays on all day without charging.
