Moebius lab?????!?!?!?!?!

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

Love all of the apps!

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

Huh?

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.

Needs Logic update

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

Nice dub, no AU3

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!
