Pocket Jam is for musicians wanting to practice and play along with their favourite songs. Loop specific sections of songs, or change the pitch or tempo in real time.

If you don't have a capo to hand — or worse, the song is in a lower tuning than you, Pocket Jam has you covered. You can change the pitch up and down — in real time — to any amount of semitones up to an octave.

Looping lets you pick specific parts of the song you want to practise. Once enabled, drag the left and right handles on the play bar to set the start and end of the loop, and it'll loop between them.

And when looping isn't enough, you can use the speed trainer. With a loop set up up, you can have it start each loop playing slowly, and gradually get faster after each loop. You can customise how slow it starts, and how many loops it takes to reach the full tempo.

Mark specific times in a song with section markers. It'll let you jump to parts or set up loops quicker.

You can add songs from your your files on device, and play them back in real time, or export them.

Doesn’t work

I am getting “playback error” nearly every time I try to play a song from my Apple Music library. Would love to talk with the developer about how to fix this.

Were you the one who emailed? Hopefully it’s all working now ☺️

Great product

This works great... wish it stepped down in 1/4 note increments instead of 1/2... also noticed when I close the app and come back next time my playlist is still there but it won’t let me play it so I have to clear list and re add them. Other than that it really works great for changing keys for different tunings on songs…
