In light of the surprising success of Yo, could a new messaging app with gamified features stand out from the crowd? That’s the question Shotclock is out to answer. At first glance, it might seem like a Snapchat copycat, with its self-destructing messages and one-tap-to-send interface. But its unique clocking system adds a twist: the time the ephemeral messages exist is proportionally linked to the “likes” and “shares” they get. Essentially a quantified popularity contest, Shotclock allows the messages with best content to last the longest and therefore gain maximal exposure.
