CashForApps is a mobile app that reward its users by gift card for downloading other apps. Yes there are more over hundreds of apps are available for this kind of job. But today I refer CashForApps only for their high paying rate. It gives $5 Gift Card after downloading only 10 apps. I don’t get any other reward app that pay this much for 10 downloads.
Below chart is showing the comparison between 5 top mobile reward apps.
Simply download CashForApps and start downloading its recommended apps to get paid. I think this is the only working fastest way to gather some free gems for Clash of clan. Either way you are free to use your gift card on various games, not only in COC.
