To set up and use this smartwatch, you usually need a smartphone or tablet with Android or iOS. Full functionality is best achieved with a Huawei smartphone, but other Android devices and iPhones are also compatible, although some functions may be limited with iPhones. A tablet can also be used as long as it supports Android or iOS, as the smartwatch is compatible with both operating systems. It is important that the device supports the Huawei Health app for setup and synchronisation.
