Ratings and reviews

I've used this app a lot to help learn harmonica songs by slowing them down without losing quality, but I've had enough of the ads on this newer version. The old one was way better Every time I pause a stupid song, a full screen ad pops up over everything while I'm using it. Then I have to close the ad if i can find the "x" to get back to the controls again. Drives me insane. Uninstalling it now!

I've used this app for...well, for YEARS. Since 2014, at least. When I found out about the equalizer, I was stoked! The issue is...when I try to export a song after modifying the equalizer, it doesn't transfer over my modifications. Is this something I have to buy? Do I have to pay money in order to export songs after using the equalizer to fix them? If so, then that's...disappointing. Might as well get rid of the other features if they're not free, either.

This is genuinely the best music speed changing app that allows you to play music in various apps without closing them. However, there's an issue. I experience ear piercing sounds when using the app, particularly during pitch or rate adjustments, which is discomforting. Please fix this issue as it affects the overall experience. But other than that, it's a good app. 👍
