Good options
Experiment a little to figure out the different kind of timers. Once u get that down its very helpful if you have multiple kinds of workouts.
Only reason I didnt give it a 5-star rating is because if you leave the app mid-workout (to change playlists for example) and you come back the audio beeps dont work anymore. They fix that big and its a 5!
