The watch also works with an iPhone, you need to download the Mi Fitness app from the App Store and pair the watch with it. A Xiaomi account is helpful, but is not necessarily tied to a Xiaomi Club. The Redmi Watch 5 is compatible with iOS version 12.0 or higher and offers basic smartwatch functions such as notifications, fitness tracking and compass, but without native support for apps such as Spotify or Apple Maps. It is operated and synchronised via the Mi Fitness app, which can also be used on the iPhone.
