How to wear correctly

Please ensure that the ring fits snugly around the base of your finger, with the sensor ideally positioned on the fingertip.
We recommend wearing the Helio Ring on the index finger for optimal performance and accuracy.
If wearing on the index finger is not suitable and you need to wear it on the middle or ring finger, please still ensure the ring meets the above requirements, ensuring a secure and comfortable fit.
It is not recommended to be worn on the thumb, where test data has shown that the accuracy of data monitoring is lower than on other fingers.
