Keeps Me Motivated!

Coach Mario is awesome! Between his regular check ins and tips, and the way use of the app, Caliber keeps me accountable.

Stopped recording workouts

Been using this app for years but recently workouts do not get recorded anymore. Can’t track my progress at all so this app is pretty much useless now

Functionality good, extremely limited exercises

I made it through the free trial, but will not pay for this app. There are extremely limited exercise exercises for each body part. I ended up having to supplement each workout with a ton of exercises on my own. Definitely not worth paying for.
