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.

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!

We are sorry for this, but to continue work on this free app we need revenue from Ads. If you don't want to see the Ads you can purchase the ad-free version from side menu. Thanks for your understanding!

While I love this app, as I can change the pitch of the song im listening to to tune my voice, I wish this could be redone to include a playlist option so I don't have to change the song every so often. Like, so I can just pick the song I want without having to stop everything all together.
