I love this app but if its not working right then I cant give it a proper rating. The app crashes all the time while Im using it, for one. Also, it never stores my data! Even if my data has been somewhat stored then itll say I only completed one challenge even though I did them all. And also sometimes Ill turn on the app expecting my progress to show, but instead it asks me to join a challenge. Ive had to keep re-joining challenges because it wont save mine. This wouldnt be so bad if it was a free app. But I paid money for it, way more than .99 cents too! This needs to be updated soon. To anyone who wants this app: DONT GET IT! Get one of the free ones. I got those and I like them a whole lot better than this one. After this app gets an upgrade and all the bugs are fixed I will encourage others to buy it but as of right now NO.
