Ratings and reviews

I really like the app would have rated five stars but the premium service isn't clear if it's a reoccurring payment or a one-time fee, also you should make it like 10 a day or 10 a week for the non-premium members otherwise after the initial 10 there's no other reason to use the app.

great app I love it.

very cool!
