Huawei Health application is the most important app for Huawei Watch GT and Huawei Watch GT 2. You can download and install new watchfaces here, there is also interesting set of settings. If you want, you can install betaversion of Huawei Health application, so you will get new features before they are release in stable version.
You will also get faster updates for your Huawei Watch. I will regulary put new informations about Huawei Health Beta here, so you can check any time if you have the latest version. Beta version is updated Over the Air only if you have Chinese Huawei ID, without Chinese Huawei Id you have to download and install new versions manually (and sometimes it is not easy to find corresponding APK). You can download Huawei Health 10.0.6.031 Beta here (mirror Google Drive).
