I've been a beta tester for a while now. This is the latest app from the folks from Stupeflix (Replay app). I love the concept and execution and I've started getting used to sending short animated messages to my friends.
It really might turn out to evolve into a new, async communication medium, the way Frontback or Vine turned out. Really excited that this is coming out of beta!
