In June, Google emphasized that Android is now powerful enough to operate devices in many different form factors due to its versatility. Today, the company is announcing the first batch of Android apps capable of being used on a Chrome OS device. The apps now compatible with a Chromebook (or any other Chrome OS device) are Duolingo, Evernote, Sight Words, and Vine.
A project called App Runtime for Chrome (Beta) makes this all possible. What is on an Android device can be seamlessly ported over to a bigger, more expansive display. In the coming months, Goole will be working with additional developers to bring their apps over to Chrome OS.
