It’s a genuine paying app, it pay you for completing task like installing apps in their offerwall, sharing apps, referring friends. But I must say it’s not worth in wasting time with this app. After installing and using these app you get just few bucks with them. It will take months to reach$10, so you can judge how slow it is? I got 2-3 withdrawals from them. It’s very good if you want you promote your Android app with them. You can get targetted traffic and install for your app with their optional plans.
