Has served me well for years!
I replaced my old wrist/velcro-style (yep!) GymBoss with the app version many years ago. It has been awesome for all my various workouts. I love that you can just rename a timer and it auto-creates a new one that can be modified. There’s been several improvements over the years. I have probably 30 timers and I’m always tweaking them or adding new ones. I don’t know what I’d do without this app!!
