Simple to use  works perfectly Only missing a star because scrubbing through tracks can be fiddly to stop at the right place  especially in longer files. I've seen other playback interfaces where the further you move your finger from the timeline (once you've touched it) the less time the marker moves in relation to your finger's movement. Be nice to see something like this implimented in the future. Otherwise  this is a great app!
