Usage recommendations

For consistent metrics, wear the ring continuously, including during sleep, and ensure the ring is properly seated on the finger for accurate sensor contact. Sync regularly with the companion app to back up data and apply firmware updates. If using temperature or HRV metrics for training or health decisions, interpret trends over several days rather than single readings and consult a healthcare professional for medical concerns.
