### 5/5 — Moebius lab?????!?!?!?!?!

*2024-12-08*

Wheres my moebius lab...just poof gone after i bought it and used it for a month...Makes me wonder why i buy anything music one off purchase on ios... PLEASE PLEASE BRING IT BACK

### 5/5 — Love all of the apps!

*2024-08-10*

Best glitch maker in the game. -coupled w/ the right drum machine, absolutely epic.

### 2/5 — Huh?

*2024-06-27*

I purchased it and it WAS working quite well as an Audio Units plugin and now it doesn’t. And now I am supposed to pay to restore its functionality? Maybe it’s still working on newer iPads, but this feels like extortion to me. What am I missing? This app would have rated 4-5 stars before it was broken.

### 4/5 — Needs Logic update

*2024-03-18*

Little filter gizmo worked great and added a ton of movement to tracks but does not work in Logic on my M1. Seems like a requirement for AUv3 now. Still usable in AUM and all the other things

### 3/5 — Nice dub, no AU3

*2023-09-10, version 2.3.2*

I used to use this a lot, but the continued failure to add AU3, as an IAP so the devs make something has made it redundant. If the devs ever add AU3, I’d be happy to buy it!

### 3/5 — I love this app but it hasn’t been updated in a year

*2023-01-15*

It won’t load in easily in AUM any longer, I have to reload it several times to stay loaded in the program. This was one of my all time favorite apps. Please amazing voices- update this for the new iPadOS

### 2/5 — 取り込もうとしたwavデータが

*2021-03-16*

取り込めずアプリの容量だけ増えて圧迫してる。データの残骸も認識できず削除もできない。セットも組んでるので、再インストールとかで対応だったら困る。

### 1/5 — Useless because of a bug

*2020-09-27*

When loaded as an Audio Unit in NanoStudio 2, the plugin changes sound parameters when closing the window. I have already reported this bug but no answer from the developer. There is also no way to get the money back...

### 5/5 — 优秀应用

*2019-11-15*

等你们来买哦

### 5/5 — It’s great
