|---|---|
| Watch does not turn on or respond. | Ensure the watch is fully charged. Connect it to the charger for at least 30 minutes. If it still doesn't respond, try a soft reset by pressing and holding the side button for 10-15 seconds. |
| Cannot pair with smartphone. | Ensure Bluetooth is enabled on your phone. Make sure the VeryFit app is installed and open. Restart both your phone and the smartwatch. Check app permissions to ensure it has access to Bluetooth and location services. If previously paired, try unpairing and re-pairing. |
| Notifications are not received. | Check notification settings within the VeryFit app. Ensure your phone's notification settings allow the VeryFit app to display alerts. Make sure the watch is connected via Bluetooth. Disable any 'Do Not Disturb' modes on both the watch and phone. |
| Inaccurate health data (HR, SpO2, Sleep). | Ensure the watch is worn snugly but comfortably on your wrist, about one finger's width above the wrist bone. Clean the sensors on the back of the watch. Avoid excessive movement during measurements. Note that these are not medical-grade measurements. |
| Short battery life. | Frequent use of features like Bluetooth calls, continuous heart rate monitoring, and screen-on time can reduce battery life. Try reducing screen brightness, turning off continuous monitoring if not needed, and limiting notifications. Ensure the watch is fully charged each time. |
