About Flipaclip

FlipaClip https://flipaclip.com/es/ is the world's biggest animation app with over +90 million lifetime installs.

FlipaClip turns any mobile device into an animation studio.

Animated movies and shows require massive budgets, years of production, or the approval of a handful of studios to exist. That's how the industry has worked for decades.

Very soon, a blockbuster animated movie will be entirely produced by a 15-year old in her parent's basement. On a phone. And it will be made and distributed for $0.

We are on it.
