Gifdub co-founder here. Thanks for the feature! App is still early -- v 1.1 coming this week -- but already seeing lots of great gifdubs being made.. Examples here: https://vid.me/n/gifdub/top
Feedback and suggestions appreciated :)
I played with it to punk some friends and loved it. As the product progresses it will be easier to create & share vids. Not sure how much I'm allowed to tell (sorry alex & warren if I reveal too much) but also alternate voices will 10x this product.
