This is a simple, yet reliable metronome. There's no subscription to worry about, and no in-app purchases. It does what it says on the tin:
- Adjustable beats per minute between 62 and 280 (let us know if you need more than that).
- Offers time signatures 2/4, 3/4, 4/4, 6/8, 9/8, and 12/8.
- Sound can be started and stopped with the big 'ol button in the middle.
- Dark mode (automatically activates with system dark mode).
- Very accurate timing.
Here's some more detail about that last point. One way to make a metronome would be asking the phone to play a sound every X milliseconds on a timer (the number of milliseconds changing depending on the BPM). But phone timers aren't accurate enough to trigger a sound to play on the *exact* millisecond necessary to keep a totally steady beat at higher BPMs. The beat will start to drift a little bit.
So this app doesn't use timers.
Instead, it constructs a brand new WAV file from its beat sounds that exactly matches the selected BPM and time signature *on demand*, then it plays that file on loop (which the system is very good at doing). This keeps your beat nice and solid. No wibbly-wobbly measures here.
Hence, this app is a great tool for piano teachers, Moms and Dads teaching music to their kids, young aspiring trombonists practicing their scales, annoying teen garage-bands who are prepping for their very first gig, or even buddies keeping in sync while building a trans-continental railroad.
