Horrible cues - and NOT a free app! – Aaptiv: #1 Audio Fitness App Review

Very little cues given as to length of intervals. A 30 second sprint is going to be different than a 10 second sprint yet no indication of how long your sprints or recovery are were given. Also, have to pay a membership fee for use of program... So not exactly a free app.
