User opinions and reviews

Great watch so far, including offline music support

thanks so much for the info. i thought it works for mastercard here in singapore

actually the OS that's running on this watch is FreeRTOS whoch is really common on Xiaomi smart watches, and this OS is skinned with HyperOS
