The Huawei Watch Ultimate, like other Huawei smartwatches, can sync with third-party apps to some extent, but there are limitations. Initially, Huawei began allowing third-party apps on its wearables, which was a significant step forward for users seeking more app variety[1]. However, there have been changes in how Huawei handles third-party app integration, particularly with health and fitness data.
For running apps, users can sync their activities with platforms like Strava using the Huawei Health app. However, this integration is limited and does not include detailed data such as heart rate and cadence[3][4]. Additionally, Huawei has restricted third-party apps from accessing GPS data since July 2023, which affects how activities can be synced with apps like Strava or Google Fit[4].
To work around these limitations, some users have explored sideloading apps onto their Huawei watches, but this method is not officially supported and may not work seamlessly with all apps[7]. Officially, users can install apps from Huawei's AppGallery, but the selection is limited compared to other platforms[9].
In summary, while the Huawei Watch Ultimate can sync with some third-party running apps, the integration is limited, and users may face restrictions in accessing detailed fitness data or using certain features with third-party apps.
