Before you start
- Confirm the ring size with the sizing guide included in the box — a snug fit gives the best readings.
- Charge the ring on its dock until the indicator shows full.
- Install the KINGSTARFit App and sign in.
Activate and pair
- Place the ring on the charging dock to wake it up.
- In the App, tap Add Device → Smart Ring and select
KSR-01 Titanium Smart Ring. - Hold the ring close to your phone and confirm the pairing request.
- Wear the ring for one full night to unlock your first sleep report.
Sleep and recovery
- Wear the ring during sleep — stages, score and trends appear on the dashboard each morning.
- Recovery reference combines resting heart rate and sleep quality over recent days.
- Premium members receive weekly and monthly recovery reports in the App.
- For the first week, keep the ring on the same finger so the trend baseline is easier to read.
Care and battery
- Rinse with fresh water after workouts; the ring is 5ATM water resistant.
- A full charge covers about 6 days of typical use; charge it during your morning routine.
Troubleshooting
- Ring not detected: place it on the dock for 10 seconds, then retry pairing.
- Gaps in sleep data: check the fit — the sensor side should rest against the underside of the finger.
- Battery drains fast: update firmware in the App and avoid extreme temperatures.
