Just pick your interval durations and click GO! "Plays well with others," so if you have favorite apps for audio or fitness tracking it will work well alongside those. Audio voice alerts or tones will momentarily lower the volume of your music or briefly pause spoken audio just long enough to hear the alert, then let you get right back to listening! This app does not track or collect any user data.
