THink this is a great app, works with no problems for me, timer and music are play/pausable from timer screnn, fade, new song, etc settings for each round during intervals... Tabata timer already avail., but can be modified and you can creat and save your own timer set ups. I use this app daily for various types of classes, strict workouts or fight drills... cant really say enough about it... nothing but praise for the app.
