If you're like me, and have had trouble with motivation to start or continue workout routines, this is honestly the perfect app. it's really easy to start, because the workouts are fairly short to start out with, and you would be astonished how much "Haha, funny number go up" (aka the plethora of statistics the app makes available) motivates you to keep going. 10/10

This app does a great job of holding you accountable. Your personal trainer puts your workout plan, nutrition goals, and messages you through the app. There are short instructional clips with every assigned workout, along with being able to ask your trainer for advice. You're able to send videos of your exercise for your trainer to evaluate. Which has been very helpful. Haven't come across any bugs. Overall, Caliber app is easy to use!

While this app doesn't work for me (being disabled) I absolutely see how awesome it is for anyone who is already active and lifting. The app allows you to choose from 4 or 5 days a week, and 30 or 45 minute workouts, which is intimidating for beginners and nigh impossible for someone like me, but I don't think I'm the target audience. If there were options for real beginners, I would be rating 5 stars. I hope to someday be able to use this clean, simple, beautiful app.
