makes it so much easier to keep my workout and sets timed and moving. I just have to listen for the bells and sound cues to move on. pretty simple to use!

This is a great app! I use for my daily routines and the intervals (exercise/activity), sets, reps, and duration work great and without a hitch. I start and it paces me through my whole routine. Thank you. Great app.
