Leap Year sale makes five top-rated iOS apps free, today only

Apple wants to emphasize the fact that 2016 is a leap year, so it's created a new app sale for iOS. As a consequence, five highly-rated apps for the company's mobile operating system are now free. If you get all of them, you save $15. The main caveat is that this deal is only available today - since February 29 is a day that only exists every four years and all that.
