Music Momentum

Guitar practice for iPhone

Slow it down. Loop the hard part. Play it for real.

Music Momentum slows any Apple Music song to a speed you can actually play, marks the riffs you're working on, and loops them until your hands know them.

What it does

Built around the bit you can't play yet

Three tools on one screen, with the controls where your thumb already is.

Speed wheel

Spin the wheel to slow a song anywhere from 30% to full speed. Save the speed with the song, and tap to flip between your practice speed and the real thing.

30% – 100% · saved per song

Markers & clips

Mark a point to jump back to, or a clip with a start and an end. Name it, nudge it by a tenth of a second, and find it as a pill under the timeline.

Points & clips · 0.1s nudges

Loop chains

Loop one clip, several clips back to back, or the whole song. While the loop runs, tap pills to add or drop clips without missing a beat.

One clip · a chain · the whole song

A look inside

Three screens, no clutter

Everything you need between takes, and nothing you don't.

PracticeThe wheel, the timeline and your markers on one screen, painted in the colours of the song's cover.
SavedEvery song you're learning, at the speed you left it, with its markers one tap away.
New MarkerDrop a point or a clip where you are, then drag or nudge it until it starts exactly on the beat.

How it works

From "how does that go?" to playing along

  1. 1

    Pick a song

    Search Apple Music or browse your own library. Music Momentum only asks for access when you first reach for a song.

  2. 2

    Find your speed

    Turn the wheel until the part is playable, then save that speed with the song for next time.

  3. 3

    Mark it and loop it

    Mark the bars you're stuck on as clips and loop them, one or several in a row, until they stick.

iCloud sync

Your practice follows you

Saved songs, their speeds and every marker sync through your own private iCloud, so whichever device you pick up is where you left off.

  • Opens on the song you were last practising
  • Keeps the screen awake while a song plays
