Metronome Lite by Piascore

Metronome Lite by Piascore turns your iPhone or iPad into a precise, easy-to-use metronome. It faithfully reproduces a mechanical metronome with ultra-high tempo accuracy (M.M. 20–300), seven rhythms for rhythm training, a timer with repeat, direct tempo input, a bordered tempo indicator for visual tracking, and real metronome sounds. It also supports background playback and lets you customize the body and background colors.

In the paid version, the app expands to 17 rhythms, adds four sounds (including Classic and One Two), a one-tap preset function to change tempo and rhythm, and removes ads.
