Getting Started — Tips for Best Results

1. Wear on your index finger for the most accurate readings. Middle and ring fingers also work well.
2. Measure your finger circumference before ordering — smart ring sizing may differ from standard ring sizing.
3. Charge before first use — plug in the included cable; the heart rate light confirms the ring has powered on successfully.
4. Download the companion app by scanning the QR code in the included manual, then pair via Bluetooth.
5. Use a standard 1A charger — do NOT use a fast/high-power charger, as it is not compatible.
