Very cool harmonizing effect

I didn’t get it at first, but after checking out some presets realized it’s best not to use Shift and only transpose by Cents. Then the app started shining. I love having all kinds of fx, they broaden my imagination and spark creativity. Will definitely use this one on some voice tracks!

Some reviewers mentioned problems, I didn’t encounter any so far, I guess the developers took care of them.

Only downside I found is, that delay slider goes from 0 to 10sec, which I guess someone might need such a high value, but maybe you could add a “zoom” button which would make the slider range say, 0 - 100ms which is a good range for subtle delay effect. Or maybe make it accept typing values. It’s possible to dial in smaller values as it is, but just thought this would make the app even better.

Great for harmonizing single voices and treble instruments

That's all I've tried so far, but it worked great with these. It's best to use this app on clean, sounds pre any effects processing, I've found.
