Google's Finance app is in desperate need of attention. If you haven't checked in on it lately, it's still stuck with Gingerbread design. No seriously, go look. Tiny header bars, legacy menus, odd layouts, and assets that look tiny or pixelated (or both) on today's high resolution devices.
Just for fun, I decided to take a look at the app and see if I could give it a fresh coat of paint, inspired by material design.
