Download the Companion App: These generic models primarily use the OKOK International (or OKOK-Health) app, though some variations run on apps like Fitdays or AIFit. Open the Google Play Store or Apple App Store and search for OKOK International to install it, or look for the specific QR code printed directly on the user instruction booklet inside the box.
Turn on Bluetooth: Ensure Bluetooth is enabled in your phone's settings menu. If you are using an Android device, you must also turn on Location Services (GPS) for the Bluetooth discovery to function correctly.
