### 5/5 — Auv3 please …

*2023-04-21*

Спасибо 
Это было давно когда вы дали миру этот эффект , 
Но хочется чтобы вы дали и auv3 
, ну и если получится добавьте творчества , функций и вашей магии 🧙✨

### 5/5 — Still useful!

*2022-05-02*

FLSM is not on the AU band wagon yet but I really like it. The IAA versions of the Kymatica fx are a perfect fit. They are stable, always work as expected and sound great.

### 5/5 — Great Delay, AUv3 Please!

*2020-09-28*

I’d love to be able to use this delay more often... AUv3 would solve the only problem this app has.

### 1/5 — Not AUV3

*2020-05-21*

I’ll upgrade this review as soon as they make it AU compliant. Great sounds but unusable in its current incarnation.

### 4/5 — Still no AU3. )-:

*2020-05-04*

This is one of the better FX apps available on IOS, yet is falling behind because it has not added AU3. Come on devs, Izzy Wizzy let’s get busy!

### 5/5 — ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

*2020-01-04, version 1.3.4*

A collection of exceptional plugins! Impressive quality and complete immersion in effects. A realism rarely seen in software of this category. I've been working in the business for over 30 years, and I've sat in front of an SPX 900/1000, or a Lexicon. Just fantastic! I recommend everyone!

### 5/5 — Legend apps from a genius

*2019-11-01*

This is the best ever and completely rewrote everything in my life on every level for the last almost 7 years of music making

### 5/5 — One more delay line and

*2019-03-03*

I could run the ring mod effect or the wobble through a Ping Pong or even the wobble through the ring mod or...great app. Clean clean clean and very cool. Lots of control and with some MIDI control it's very "playable".

This is crack for delay lovers. And hands on its hands down it’s the best delay on iOS.

### 5/5 — Ja! Gute

*2019-02-03*

App! alle klingen hochwertig. ❤️

### 5/5 — Great tool if you’re into delay plugs

*2018-12-24*

This one has its own character. Nice simple layout with some extra parameters that are actually useful and unique and not just frills. Very stable on my 5 year iPad mini. Good price.
