I use these sites everyday, it's very easy to get free games and gift cards! You just download the sponsor apps (free), and you get points that you can redeem. I can get at least a few dollars worth per day.
You will need to allow them to access your UID (install profile) but this just lets them confirm that you have downloaded and opened the free apps - it does not effect the security of your account.
Another great app (iOS or Android):
Viggle - you just check into whatever you are watching on TV and earn points. If you check into featured shows, or watch little ads, you get bonus points. Use your points to redeem for a variety of rewards including gift cards.
