This app rewards you with points that you can exchange for real money. In theory there is 2 ways to earn money, one is by taking surveis and the other one is by downloading apps that are listed on the hub of Feature points, use them and write a review of those apps.
I registered at Feature points and my experience was that you can earn points making surveis but that's it. No apps to review ever showed at the list where they are supposed to be shown. So it was not possible for me to download and review apps of games or whatever apps that were supposed to be shown to review. Also, in my experience surveis asks mainly personal information, a lot of personal information, and they want you to answer your real info.
Since I don't want to sell all my personal detailed information (personal, profesional and non profesional, including what I have or I don't have at my house) to companies that I don't even know, I stopped using Feature points app.
