Unfortunately, Muscle Booster does not currently integrate with any other smartwatch besides the Apple Watch.
Muscle Booster's integration with Apple Watch is primarily used to track exercise, calories, and heart rate during a workout. However, there’s currently no streamlined integration with the Activity App provided in the app, which is why data transfer is not always aligned.
If you are interested in seeing Muscle Booster integrate with other smartwatches, we would greatly appreciate it if you reach out to us via the Contact Us form and let us know your smartwatch preferences to pass onto our team for consideration.
