So useful
As a personal trainer and a group exercise instructor I absolutely love this app. I teach 8-15 classes a week and this timer is all that I use. I have all my workouts organized by year and month. I also use this for clients and I have them download it and I send them their work out so they can do it on their own with my instruction and timing. I have been using this app for many years and I absolutely love it.
