Oh my God

Never do I really write reviews for app but this one is a little different. I listen to hundreds of different genres weekly to provide the most amount of variety. This app adds an entirely new element to that. I’ve been listening to my RnB and Lo-Fi playlist now for HOURS because of this app. Just buy it, oh my goodness

Does exactly what I need

I've got a lower voice than most of the artists whose songs I like. As a result, sometimes it's hard to sing along belt out the tunes, because there are parts I just can't hit. This app let's me easily drop the pitch to a key more manageable for me. Also changes tempo simply, but I haven't had need for that feature.

Latest update destroyed primary functionality

I downloaded this app a couple years ago and used it almost daily for its pitch shifting abilities. I have no idea why y’all got rid of that. The new design is clunky and ugly as well. I’m super disappointed with this update, I really hope the pitch change ability is restored soon, otherwise I’m uninstalling.

Developer Response ,

You can still change the key of any song that you have downloaded to your device providing it does not contain DRM. This is the same as the previous version. Because we now can play Apple Music songs that do contain DRM, many songs do not support being transposed. So we decided to hide the pitch changing controls by default. To enable these controls, use the Settings app, locate the Perfect Tempo section and switch on ‘Show Transposition Controls’. When enabled, these controls can be accessed by swiping left on the album artwork on the playback screen in Perfect Tempo.
