Charge the ring with the included USB‑C cable before first use and keep it regularly charged to maintain continuous monitoring. For accurate nightly sleep and respiratory readings, wear the ring while sleeping and ensure the sensors have skin contact throughout the night. Sync data to the app to view detailed summaries and trend graphs.

Usage recommendations

For reliable SpO2 and heart rate measurements, clean the ring and dry the finger before use, and avoid loose placement. Use the companion app to review AI‑generated sleep health insights and enable integrations with health platforms such as Google Fit to consolidate data. Remove the ring only when charging or when it may be exposed to corrosive chemicals; regular short charging cycles help maintain battery longevity.
