Great app! I've been looking for this...

Finally, an app that allows me to change to speed of a song without changing the pitch!

I love that I can pitch control songs already on my phone. I teach dance classes, and sometimes you want to use a song on your phone, not a CD to teach, but you need to slow it down. This app is perfect for that!

Best available

I use it for guitar and it’s fantastic for practicing. The ui is neat but can feel a little clunky moving around sometimes. Dislike having to import files from Dropbox as opposed to being able to read directly from iOS folders but perhaps that’s a limitation of iOS and not the app itself. Really wish you could have multiple start/stop slices for 1 song. Right now you can only have 1 but at least it remembers when you come back to song after switching to a different one so it’s not the end of the world. Good job by the developer

Developer Response ,

Thank you for review! You can save up to 3 repeat sections for each song. Tap the down arrow icon at the bottom right of the screen and tap the 1 to 3 icons to switch the repeat section. I will consider the function to import songs from iOS Files.

Awkward interface

I was struck by the feature list of what it can do in theory, such as save loops, but it’s too hard to use in practice. I’m only willing to put so much effort into wrestling with a funky interface before bailing on an app. In the end the perhaps overly inventive interface is just awkward, although cute as heck.

A deal-breaking negative is that the interface sits sideways on my iPad Pro - no beuno. I suppose I could sit the device sideways, but then you lose control over the viewing angle for the screen. Awkward.

PS: I note that across the board iOS apps continue to be markedly inferior to Mac apps in almost every instance - on the Mac the Amazing Slow Downer is infinitely superior to its dumbed down iOS version (which cannot save loops) and to Robick as well, of course.

Developer Response ,

Thank you for review.
This application aims to be easy to use when operating many times. However, as you pointed out, the interface is not common, so it may be difficult to understand how to use it.

By tapping the "i" icon in the lower right corner of the main screen you will see a simple operation method, so I hope this will help you.

If you have any questions about how to use please feel free to contact support.
