Some new Android apps are now available for Chrome OS and Chromebook users from the Chrome Web Store. Yo, the limited but still inexplicably popular messaging app, is among those on that list, along with the SlideShare presentation app and the Tapatalk forum discussion app (with which our forums are compatible).
Some developers have been porting their Android apps over to Chrome OS for the past few months. This effort is part of Google's App Runtime for Chrome Beta program, which was announced at the 2014 edition of Google I/O. You can humbly offer the company your suggestions for which Android apps should appear next on Chrome OS next at the Chromebook website.
