While we're redesigning Android apps, I thought I'd throw out a redesign I did.
I love Uber, but the design is lacking just a little. This is basically just a skinning, but I made a few UX modifications. I could probably make more, but they'd require a wireframe, not just a single PNG.
It's simple, but fits in with the OS much better. Apps can look different across platforms (iOS and Android) while maintaining a brand identity.
