### 1/5 — Waste

*2026-05-03*

Does not work. Make sure you perform/upload your projects into a daw.

### 1/5 — Really wanted this to work

*2025-08-10*

Sadly on my iPhone 15 Pro this app simply displays the splash screen then quits.

### 1/5 — It sucked want my money back

*2025-03-26*

It don’t work end of story $15 dollars that I want back and I feel like I’m entitled to $20 for having to go through the trouble of getting the app

### 1/5 — Don’t waste your time ( or money)

*2025-03-21*

Total garbage app. Wasn’t worth downloading. Crashes constantly

### 1/5 — doesn’t work

*2025-02-23*

I was excited to see an app like this as i was disappointed that TE didn’t have anything offline that didn’t require internet connection and thought an app was a good idea. I paid $15 and it doesn’t work. it just doesn’t work. i connect my ep-133 to my phone with c to c charger cable, hit backup button, wait as it shows a progress bar slowly fill (indicating that it’s doing something), then…. nothing. no backup. nothing happens. i’m so angry that i can’t get a refund on an app that doesn’t do the only thing it’s designed for. i got denied on my refund request. i submitted an appeal explaining the app doesn’t work. It doesn’t do the only thing it advertises and that i spent $15 and should be entitled to it back but my appeal was denied. don’t waste your money. I’m really frustrated and angry at being taken advantage of.

### 1/5 — $15 for a File-Saving App? Way Pricier Than Most in the App Store!

*2024-12-20*

I was excited to download it because it said it was free. I would’ve been fine paying a couple of bucks, but it turned out to cost $15. That’s much more expensive than most apps in the App Store with similar functionality! I wouldn’t mind paying a small fee, but $15 feels a bit steep for an app that’s primarily for saving files. Maybe the price would be justifiable if it allowed uploading and downloading samples like the web app does.

### 2/5 — Pitched down

*2025-12-13*

Okay I love this idea and didn’t have the same problems as others. When I restored my first backup every sound was pitched down. Hoping this can be addressed in an update, I would love to use this.

### 5/5 — My bad

*2025-07-31*

Actually , I m here now to say sorry , I figure out that my phone is tha the latest , but I was able to download the app in my laptop and is working perfectly t and exporting  the files,  is actually better than using the phone , so thanks for that , and I apologize completely about my past reviews based on my lack of knowledge, thank you ! For making this happened and il give you 10 stars , and I’ll give you authorization to delete the past bad review I left .

### 5/5 — So excited to see a Teenage Engineering app on iOS

*2024-11-20*

This app is awesome - obviously it backs up your Ko ii - onto your device, without the need for going online to the TE website for the ep-133 browser tool. I hope to see the ability to navigate/edit folders and samples too one day; as it is fantastic work and thank you for making this!
