I like the app a lot - simple for someone like me new to working out everyday (attempting...) I love how easy it is to use and the cost is pretty low! I use it when I travel or at home so the ease is great. They recently had an update, and no longer supported on my tablet which sucks - and the sound was difficult to find, since I mostly listen for the sounds. A few other glitches have been noticed but I am hoping they come out with a fix soon and support Google products to use as well!

I was looking for an app that allowed me to make my out workouts and that had recommendations or tips on performing the exercises! Which the app doesn't let you down at all in that aspect. The app even recommends an entire meal plan which is sweet. I only wish it also had a calorie counter and water intake tracker as well! That would really complete the experience! What say you?

BEWARE WHEN YOU SUBSCRIBE! When you subscribe on the Play Store, the app also keeps your subscription saved in their system. So you have to subscribe on the play store AND their app! BUYER BEWARE! I canceled my subscription a while back because I found an app that's $45/year instead of $22/month, and just woke up to a $67 charge from this place I'm paying ~$200/year LESS for the other app. Do your research on your Home Workouts and what apps there are out there.
