Do you need your phone during a session?
The ring saves sessions in its own memory. Review the record in ViHealth after your session and confirm that it transferred before clearing device data.
What the reminders mean
The ring can vibrate when a configured threshold is reached. Check the instructions for when it activates and how to adjust it. Talk to your health professional if you need medical monitoring.
Ring or a wrist display with a finger sensor
A ring keeps the components on your finger. The Wellue Checkme O2 Ultra puts its display and battery on your wrist. Compare where the sensor sits and how you want to review recordings.
