Get PayPal, Steam, or Amazon gift vouchers
AppNana is an application that lets you get gift vouchers for PayPal, Amazon, Google Play, iTunes, and Steam, among other companies. To do so, all you have to do is try the applications suggested by AppNana. But, of course, you'll have to try quite a lot.
When you register on AppNana, you'll receive 10,000 nanas, which is the currency used by the app. To give you an idea of how much money these 10,000 nanas are worth, you can take a look at some of the cheapest gift vouchers. For example, a PayPal gift voucher for $1.40 euros costs 45,000 nanas. So just for registering, you automatically get about 30 cents.
AppNana is an interesting application thanks to which you can get real money to use on important platforms like Steam, PayPal, and Amazon.
