### 1/5 — Used to be a great tool for learning songs

*2026-01-15, version 3.6.42*

I used this for years exclusively to learn songs. The song audio used to play through my iPhone and iPad speakers. Around 5 years ago it stopped playing audio through the speakers. Fortunately I found other apps that plays through the device speakers and has A / B loop feature.

### 1/5 — Waste

*2025-09-04, version 3.6.42*

What a waste of money. The software is so buggy, not to mention the interface is so delicate. I would never try to practice with this, not to mention gig with it. Take some advice and stick with pedals.

### 4/5 — Atualização

*2025-03-05*

Ótimo app, mas precisa de atualização para IOS 18 ou superior. Inserir a opção de Allow Network por exemplo o que possibilitaria compatibilidade total com o Audiobus.

### 2/5 — Problem with devices

*2025-02-03*

I buy this app on my iPhone, but when I download at my iPad my licence is not purchased. How can, I fix this?

### 4/5 — Não funciona com o Audiobus 3

*2024-09-05*

No consigo fazer o programa funcionar com o áudio bus 3.

### 1/5 — It stopped working…

*2024-07-18, version 3.6.42*

I had this app for a few years and it worked flawlessly. Suddenly it stopped working and I  contacted the support team with no real help or acceptable outcome. Uninstalled and reinstalled the app million times and nothing. i’m very disappointed.

### 1/5 — Doesn’t work at all for any new device above iPhone 7

*2024-05-18, version 3.6.42*

This app doesn’t work at all for any new iPhone. I actually have to keep an old iPhone 7 laying around just to play with this app. It’s useless and officially a waste of money

### 5/5 — ios 17.4.1

*2024-03-27, version 3.6.42*

Sound is not coming out properly on iOS 17.4.1

### 5/5 — Please fix! Unable to reach settings

*2024-02-22, version 3.6.42*

Ios 17 broke jamup pro, now strip of the screen on the right is unresponsive so no settings!

Also barely works in loopy any more, and i JUST got a new ipad to finally use this rig I have been building for 13 years!!!! Please fix! And update to AU3 if you want!

### 1/5 — Used to be the best phone app

*2024-01-14, version 3.6.42*

This app was by far the best app I’ve had. Better than anything, but for the last year, it doesn’t work. The microphone picks up noise but the actual app doesn’t do anything. I was due a new phone anyway thinking this would fix it, I eventually brought a new guitar lead, iRig, headphone adapter, headphones and realised the app’s knackered. The developers seem to not care for this app anymore. Shame.
