Tab bar animation concept for mobile app
Creative animation concept by Vitaly Rubtsov aiming to improve mobile app controls. Vitaly explained his idea behind this concept: Big screens are everywhere. Screens are getting bigger, but somehow design doesn’t adapt to this change. I think we should fix that. Inspired and guided by a simple inference I came up with an idea to put all the controls at the bottom of the screen. This will allow a user manage an app with one hand.

Developers at Yalantis brought this concept to live and it’s available on GitHub.
