Tack is a beautiful and simple metronome for Android Wear OS. It is developed with the help of the open-source app "Metronome-Android" from James Fenn. It is based on the Android system and uses the built-in Android system to determine the frequency of the sound. It has an adjustable sweep speed and a separate metronome for music practice. It can be used as a very accurate and beautiful metronome for playing a musical instrument. It is also perfect for practicing a song with the help of the music track.

In addition, there is a separate Wear OS app available (in the Wear OS Play Store or after installing the app on the mobile phone at Android Wear), with many options directly on your smartwatch.
