Popular Questions
How do I find my watch model?
Check the model label on your packaging and your order confirmation. A different watch face does not identify a different model. If you are unsure, send support a photo of the device and its model label.
Which app should I use?
Choose your model above and follow the app named in the instructions supplied with your device. Our existing manuals name G Band or H Band depending on the model and version. A shared interface does not mean the apps or available features are interchangeable.
What should I check if my watch will not charge?
Check the supplied cable, contact alignment and USB power source against your model guide. Keep the device and contacts clean and dry. Stop using a damaged cable or device and contact support if charging does not start.
Do all models support the same health features?
No. Follow the instructions for your specific device. App screenshots are demonstrations and may include menus unavailable on your model. Health records are for general wellness reference, not diagnosis or treatment.
Where can I get the right manual?
Open your model guide for setup and troubleshooting first. If a matching download is not available, contact support with your model, a packaging-label photo and your preferred language. We will help identify the matching guide.
