The watch supports heart rate measurement and can be used with various apps, as it is compatible with Android and supports many third-party apps. Whether the heart rate measurement can be shared directly with three specific apps at the same time is not explicitly mentioned in the official specifications. Synchronisation with apps such as Strava, Spotify and AllTrails is possible, but the simultaneous, automatic transfer of heart rate data to three apps is not clearly documented.

I'm not entirely sure whether the heart rate measurement can be shared directly with three apps at the same time. The information I have does not fully answer this question. For a precise answer, I recommend taking a look at the app documentation or the Community.
