Biosyntria Thalexa Smart Ring

Before you order: phone compatibility

Thalexa uses the SHR ring app. The app is not compatible with Samsung phones. The listed operating system requirements are Android 5.0+ and iOS 12.0+; meeting the Android version requirement does not override the Samsung exclusion.

Find your ring size

Use the Biosyntria Smart Ring Size Kit before choosing your Thalexa size, as smart ring sizing may differ from standard jewellery sizes. Measure the finger you intend to wear the ring on. Choose a secure, comfortable fit at the base of your finger that does not rotate during daily activities. Select your confirmed size from the available product options.
