Why just don't post the link or the name of the app in the OP?
Are you sure that this will be the app, where's your proof that they pay you already.
I was using this app in past and earning $5 Amazon Gift card per week, actually i installed this app in 5 phones (so profit per week 25$)
Check proof in below Screenshot which i got in email confirming the sweepstakes and guaranteed rewards:

P.S. I don't use this app now, and also i'm not sure OP talking about the same method to earn $5.
