Great app, but.....

The app could really use a A B Loop point system and a playlist function so that I don’t have to manually change songs each time or listen to the beginnings of songs or parts I don’t like in general



Thanks for producing such a great app! Straightforward and easy to use interface, works well; takes up very little space. Some similar apps require you to import the song which increases the storage requirement; this one does not.

One feature which would be great to add is the ability to save settings for a song so that the next time that song were loaded, the settings could be applied. I bet folks would pay an in-app purchase fee to have that feature; I know I would.

iOS 13 update created one issue

As of the iOS 13 compatibility update, regardless of which category you choose (songs, albums, artists, genres) they will always be listed in order of artist’s alphabetical order. This makes it difficult to quickly find a certain song or album.

Developer Response ,

Thank you for using. Sorry, it's my mistake. We will add the loop function again with the next minor update.
