The Beats per minute (BPM) indicator in the center of the screen displays the tempo of the metronome when started using the "Start/Stop" button.
The desired BPM can be set by scrolling or using the buttons next to the indicator.
The option to choose different time signatures (Beats per bar) and accents (Clicks per beat), located above the buttons, allows you to customize the metronome pattern for your practicing needs.
