About this app

"7/16 time with 3 handclaps and 7 snare hits per bar."
"3/4 time that gets faster as your phone points north."
"Speed up every bar until you reach 999 BPM."

Does a metronome really need features like these?

Probably not. But we added as many as we could.

OVER-SPEC METRONOME is an Android metronome packed with 112 settings, covering everything from basic beat keeping to odd time signatures, polyrhythms, sound design, practice tools, automatic tempo changes, sensor controls, presets, and setlists.

Want to adjust BPM in 0.1 increments?
Accent only prime-numbered beats?
Make the timing slightly imperfect like a human?
Change tempo by tilting your phone?
Control BPM using latitude?

You can.

Of course, it also works as a perfectly normal metronome.

All excessive features are free. Premium removes ads, adds settings export/import, and unlocks Normal Metronome view, which hides the excessive options.
