What it looks like
How to practise with a metronome
Start slower than you thinkFind the tempo at which you play the passage cleanly every time, and begin there.
Subdivide the hard bitsFeeling eighths or sixteenths between the beats stops you rushing the gaps.
Move up in small stepsA few BPM at a time. When it gets messy, step back down.
Feeling the beat instead of hearing it has one more advantage: the click never covers the note you are trying to hear. When you do need to hear it — a band rehearsal, a lesson — switch on the audible click.
Free, with a one-time Pro
The metronome, tap tempo, subdivisions, practice history and 2/4, 3/4, 4/4 and 6/8 are free. PocketBeat Pro, a one-time purchase, unlocks the odd and compound meters: 5/4, 7/8 and 12/8.
Honest about the limits
Haptics need the Taptic Engine. Every recent iPhone has one; hold the phone or keep it touching you to feel it.
Silent by default. The audible click is one switch away.
No account. Your practice minutes stay on your iPhone.
