Folks are always looking for easy ways to make money, and with advertisements as prominent as they've ever been in this Digital Age, it's perhaps more surprising we don't see many more apps like Locket, a new Android gem allowing users to earn a cent by unlocking their ad-befuddled lock screens. With a maximum of $0.03 cents to be earned per hour, the maximum one could amass during the course of a year - working 24 hours day - is little over $250, and considering the amount of effort involved, Locket won't be making anybody rich anytime soon; except its developers.
