### 4/5 — Einiges an Effekten mit Grandiose UI aber ohne Frezze Button

*2026-05-21*

hoffe sehr dass das noch hinzu kommt ebenso ein paar neue Effekte wie zum Beispiel
Shimmer, Reverb, Reflection, Wave Shaper ect.. Wäre wirklich sehr schade bei der gelungenen Benutzeroberfläche.

# Popsicle wird in  AUM sehr oft nicht geladen. Fehlermeldung „Bad Signal“. Lösung?

### 5/5 — 製品の出来はとても良いです

*2026-03-27*

最初、GaragebandでAUv3プラグインとして使おうとすると、Phaserを選んだ途端に、すべての音が止まってしまう不具合が起きていた。ところがAudiobus3ですべての機能が問題なく使えることを確認した後は、Garagebandでも不具合は起きなくなっていた。釈然としないが、この製品そのものの出来は良いと思います。

### 1/5 — App not working

*2026-03-01, version 1.1*

Trying to use the app, the app says the audio is coming out but volume meter says 0, running newest ios as of feb 28 2026 please help

### 5/5 — BRILLIANT

*2025-08-30*

This is pure genius. You can create complex morphs and Crossfades and the effects themselves sound fantastic. I usually avoid digital modulation effects finding them to be thin or insipid. Not with this bad boy. The filter sounds great too and being able to automate sweeps is a great feature. The interface is clear and easy to use and the knobs respond perfectly. I have XY pads set up in loopy pro to adjust effects parameters but that limits you to just two. This goes way beyond.

### 1/5 — 🙁🙁🙁🙁🙁🙁🙁🙁🙁🙁🙁🙁🙁🙁🙁

*2023-11-13, version 1.1*

Doesn’t maintain his apps bugs are forgotten

### 5/5 — Top shelf.

*2023-01-27, version 1.1*

This is a fantastic fx app. Think a Korg KP3+ with better sounds and way more flexibility and control.
Really well done.

### 5/5 — Popsicle Fx has melted

*2022-08-07, version 1.1*

I bought this a second time when it went on sale following a refund, explained below. This time no problems. Don’t know why it didn’t work before. Great app. Five stars. 

I don’t want to diss Kia Aras or his apps. I don’t want to overly criticize any developer. I understand how difficult it is to come up with an app from scratch and then deal with Apple. I bought Popsicle FX and it worked until I upgraded my iPad Pro to the latest iOS, 15.4. I expected some of the older, IAA apps to crash, and they did, but one I bought a month ago? I feel strongly about this, mainly because I did a video praising this app, now it is braindead. I tried to contact the developer to discuss this; the contact link on his webpage does not work. I don’t want to leave a negative review, primarily because when this app worked, I loved it. This morning I downloaded the “fix” (for the ancient iOS 12) and of course this didn’t fix the crash issue. So, I either wait for Mr. Aras to address this issue, or I ask for a refund. I simply have too many malfunctioning or now useless apps on my iPad. That’s quite a bit of money. I love working on the iPad, I love touch opposed to a mouse, but it looks like I may go back to Logic Pro. The plugins there always seem to work and the developers usually state what OS version it will work with. With iOS apps, you’re always taking a chance.

### 5/5 — Great

*2022-08-03*

Great stuff, make sure you’re updated to 15.6, otherwise it won’t show up in the audio unit list

### 5/5 — Thanks to Dev for fixing iOS 12 Issue!

*2022-04-07, version 1.0.2*

Tested app in AUM and it now loads and functions properly.

Thank you for the fix!

### 3/5 — Echo

*2022-04-06, version 1.0.2*

Echo effect isn’t showing up in basic mode. Tried clicking on it, didn’t work. I also tried using the plus and minus. Skipped echo entirely. This happens on program A. Program B Echo is present
