During the Google I/O keynote, we learned that Google is preparing the biggest update to their wearable OS, Android Wear 2.0. With Android Wear 2.0, Google says they'll start to allow standalone apps. This means apps can directly communicate to the cloud via LTE or WiFi if the hardware supports it. The Complications API will allow watch face developers to show snippets of information like the current date or moon phases. Google also announced they will be redoing the user interface for Android Wear. We'll start to see refinements like notifications using a light font on a dark background. They announced a tiny keyboard and handwriting feature for Android Wear 2.0, added features for Google Fit, and the ability to try out the new update before it's released thanks to a Android Wear developer preview.
