### 1/5 — Not good

*2025-07-17*

Does not work

### 2/5 — It crashes when I open in Logic Pro for iPad

*2025-05-17, version 1.20*

Please help how can I stop it from crashing

### 1/5 — Honestly just terrible, please don’t buy

*2025-05-05, version 1.20*

I wanted to test this out, but it’s not worth the money. I tried using it on raw vocals, but the pitching isn’t right, it’s kind of drastically changing pitches instead of correctly tuning it. Honestly, the stock pitch correction on Logic works better than this.

### 1/5 — Doesn’t work in lumafusion

*2025-01-07, version 1.20*

If you want to sound like a demon get this app lol. It sounds like your recording got possessed. It doesn’t let you adjust the speed. It has zero functionality in lumafusion though technically you can use it as a worthless plugin

Please fix it

### 1/5 — Buggy

*2024-03-12, version 1.20*

Leaving the project changes all the settings or resets to default

### 2/5 — Errors with basic functions

*2023-09-15*

The app itself is stunning, but the fact that the keys aren’t correctly implemented—is a complete deal breaker. I put the plugin in the key of C# major and it’s autocorrecting notes that I’m singing to a “B natural” when that’s not even in the key of C# major. I didn’t accidentally put it on custom key either. Also, I noticed that when I would sing the “B natural” it would say I was singing a “C natural.” So, that’s incorrect. Anyways, please fix this! This app has great potential, and I’ll change my rating if this is fixed.

### 1/5 — It's got a ways to go.

*2023-08-20, version 1.20*

LOL. It harvested a song from Files, destructively tuned it badly and then saved only the copy in place of the original. I spent $3.99 on nothing and lost a track. Wifffahhhh!

### 4/5 — Works Great but has one issue

*2023-07-02*

I set the amount at 18% and save song.  When I open song the amount is back at 100%.  The dial is still at 18% and I have to turn it all the way up and then back down to 18%.  I check % by going to numbers screen.

### 4/5 — Great, needs a bug fix

*2023-06-18*

I love this plugin and it works really well but every time I try to save something on GarageBand it either glitches the octave or sets the amount all the up, it’s quite annoying and it does that when I try to export the song too. Overall good plug-in just needs a couple bugs patched!

### 3/5 — Works! Needs update

*2023-06-17*

This is the only auto tune application available for iOS. Works only for certain apps. Any update coming soo? as it doesn’t load with Logic Pro
