Last year, Google unveiled its design vision for the future. Called Material Design, it incorporates bold colors, flat elements, and informative animations to create a fresh user interface for the modern age. Material Design made its major debut with the launch of Android 5.0 Lollipop in the fall, and Google has been rapidly updating its own apps and services to take advantage of the new design directives.
Google isn't the only one that's been applying Material Design ideas to its apps: plenty of third-party Android app makers have released refreshed and overhauled apps to match Google's new platform. These apps often look and feel great, and they're typically much more enjoyable to use than older Android apps thanks to their fun animations and delightful transitions.
Here are 10 Android apps that have taken advantage of Google's new tools to provide fresh takes on old ideas. (Note: if you don't yet have Android 5.0 Lollipop on your phone, you can still install and use these apps. The designs and appearances will be the same, but older phones won't support all of the animations and transitions possible with Lollipop.)
