I've been looking all over for an app that motivates me to work out everyday until I found this. I downloaded the free version and it was not enough because I wanted more, then I downloaded the full package and since then I dropped 50 pounds in 6 months and I'm in the best shape of my life. I dare you to download all four and be consistent every day. Believe me, you will not regret it!
