TapCash offers you a way to make money for free, by downloading sponsored apps and games through the app.

Each app or game that you download, install and run rewards you with a certain amount of credits. Once you have enough credits you can exchange redeem them for PayPal cash vouchers or Amazon gift cards. You can earn extra credits by sharing TapCash with friends.

You won't make millions, and you'll end up with lots of unwanted apps, but TapCash is an easy way to make a quick buck.
