Here I review "Wild Wallet." I have it for my smart phone. It's pretty cool to earn money IF you supplement it with other apps (that I will introduce later) and share it among your friends. You could definitely earn a supplemental income if you go about it the right way. It has good reviews. ALWAYS make sure the app has good reviews before you devote some time and effort to it. Don't get burned!
I like it as well because it allows me to check out apps that I wouldn't otherwise check out. It gives you credits per download and some of the apps are cool.
