Tack: Metronome

A simple and beautiful metronome app for Android that has all the features you need for practicing a music piece accurate to the beat.

There is also a separate Wear OS app available with many options directly on your smartwatch. The Wear OS app on your wrist is perfect when you’re playing flute or a similar music instrument.
The app for Wear OS by Google is available in the Wear OS Play Store.

The idea behind Tack is to develop a nearly perfect metronome for WearOS watches.
