## What is Pocket Jam?

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 Apple Music library — streaming or downloads — or from your Files on device, and play them back in real time, or export them. Pitch adjustments and file exporting are not available when streaming from Apple Music.

### 5/5 — Finally

*2026-07-13*

Finally a music app that is truly EASY to use! Thanks pocket jam🙏🏽😊

### 1/5 — Don’t bother

*2026-05-16*

Very disappointing user experience on iPhone and iPad.
I regret the purchase.  Almost the same as the free “Music Suite
“

**Developer response:** Hello! This app is now under new ownership and I’m currently working hard on improving it. I’d be glad to hear your suggestions! Please send an email to pocketjam@bluebanana-software.com

### 3/5 — It okay

*2026-04-06*

This can’t play Apple Music

**Developer response:** Thank you! 😊

### 5/5 — My favorite app

*2026-02-27*

I have had this app for a few years now and it’s helped me tremendously in practicing for church or transposing so I can play with the song. My favorite thing is being able to change the tempo to go from learning to perfection. I will continue using this app and am excited for new updates!!

### 5/5 — S.

*2026-02-21*

Die app macht das was sie soll, Tempo und Tonhöhe beliebig verändern,sehr übersichtlich und schlicht aufgebaut, sowas habe ich gesucht

**Developer response:** Danke 🤩

### 5/5 — Great learning resource!

*2026-02-15*

I’ve used this app for several years to dissect parts of songs I want to learn. The loop and tempo feature is invaluable. Has really helped me get better as a musician.

**Developer response:** Thank you 🤩

### 1/5 — QUIT ASKING FOR REVIEWS ONCE I’VE RATED IT!!!!!!!

*2025-12-27*

Get a grip folks! Once I’ve rated your program ***** don’t keep nagging me for a review every time I start the program. Very sloppy programming.

**Developer response:** Could you reach out via the ‘email developer’ link? You can find it by tapping the question mark icon in the top left

### 5/5 — Great program!!

*2025-12-21*

Our music director is constantly shifting the performance keys of the pieces we do and, as an instrumentalist, I like to practice against the recordings I find online. This program allows me to easily pitch shift so my performance matchs the recordings. And being able to slow down the tempo and loop sections for learning and practice is invaluable.

**Developer response:** It can also access your files, and Dropbox should work too. When you add music, choose ‘Files’. Click the ‘Browse’ tab at the bottom twice to take you to a page with ‘Locations’. If you don’t already see Dropbox listed, click the three dots in the top right hand corner, ‘Edit’, and enable Dropbox. You should be good to go from there!

### 1/5 — Not Work with Apple Music

*2025-11-27*

Pocket Jam is disappointing. The app promises Apple Music song import, but in reality this feature simply doesn’t work. Until they fix this, it doesn’t deliver what it advertises.

**Developer response:** Sorry you have issues with the app. I need a bit more information to fix the issue you describe - use the ‘contact developer’ link in the app. It’s under the question mark (?) icon

### 5/5 — Does exactly what it says

*2025-07-21*

Able to change pitch and tempo on the fly is super helpful with arrangement and transcription of passages of music. Great little app.

**Developer response:** Thank you 🤩
