SlideJoy

How it works: SlideJoy is an app that pays you a steady amount of money to display ads on your lock screen. The ads don’t interfere with anything and they go away after you unlock.

 

Payment: Average earning is $3 to $5 a month. Get paid in cash or giftcards. Must have SlideJoy installed for at least 1 month, and earned $2 to cash out.
