Is there an Openoffice app for android or chromebook?

Can Openoffice be used on android or on a chromebook? Officially there is no OpenOffice app for android or chrome os. 

However, there is one on Google play that is based on the openoffice code and that is very similar, if not the same. 

It's called AndroOpen Office and it's based on the latest version of Openoffice, this can be seen if we access the app's settings. 

It has the classic word processor, the option to create presentations, calc sheets, math formulas, drawing... The same as in OpenOffice. 

This is how it looks on a chromebook or tablet. 

This is how it would look on an android mobile ... On the right you can see how it looks when touching the in-mouse icon. 

In chromeboks, there is also the possibility of installing the official Openoffice through Linux beta, but it is a little more complicated than installing an app from Google Play.
