It is an app called AppTrailers
it works and to show you i will give a account from paypal
I know it is kinda hard to see but the highlighted part says $14.69 sent from appredeem which is where the payments from apptrilers come from and it was done one june 18th. the payments are instant.
You can download the app on Iphone or Android
Within this year alone i have received about 60 bucks. All you have to do is watch videos that are like 30 sec long 5points or 3 points once you hit 500 you can start to redeem for paypal which is = to 50 cent but I cash out at the end of the month and I make on average $25 a month.
Go ahead give it a shot
