Tack

Tack is a simple and beautiful metronome app for Android designed to help you practice music with perfect timing. It provides all the essential features needed for beat-accurate sessions, including beat emphasis, various sound options, and the ability to save frequently used BPM values as bookmarks for quick access.

A key feature is the separate, full-featured Wear OS app, which brings powerful controls directly to your smartwatch. This is especially useful for musicians playing instruments like the flute, where accessing a phone is inconvenient. The Wear OS app supports rotary input, side button controls, and even wrist gestures.

Best of all, Tack is completely free and user-focused:
