Excuse Clock is the perfect trick for when you’re running late – just reset the clock and voila, you’re right on time. Or, say you want to get out of a boring meeting. Crank the time forward, get up and leave. Now that everyone uses their phone as a watch… and phones are automatically set for the right time, it’s amazing how people get faked out by Excuse Clock. This version of Excuse Clock allows you to re-set the time from a minute to sixty minutes behind or ahead, then displays your fake time in a totally convincing lock screen. Excuse Clock was made by Best Buy Mobile for members of their Happy 24 program – just for the fun of it.

Its available for both iPhone and Android.
