5 stars: The android version is improving regularly. It allows me to work across devices. I can switch between word processors on different devices. It is invaluable. I couldn't operate without it. I have the PRO version. When I get a new device and install, the PRO comes with it. It works offline. I combine it with Dropbox and Google Drive to share documents. There are continual improvements. June 2022 - after 3 years, still cheering!
5 stars: An absolutely herculean effort to port OpenOffice to Android. I've only ever used Writer, but it has been extremely helpful to be able to use OpenOffice on my phone. There is one bug in Writer which should be fixed: when carriage return is tapped when the typing cursor is at the end of a line of text, the last word on that line is moved to the next line (instead of just moving the typing cursor to the next line).
4 stars: Pro's. Stable and reliable. Only full featured OpenDocument office suite available. Seamless Dropbox support. Works well on a Chrome OS tablet. Supports input from onscreen keyboards. Con's: GUI is somewhat clunky, takes a learning curve. Does not support newer MS formats - must convert to OpenDocument formats. Overall: Good solution for my use case, may not be for everyone.
4 stars: Appears to work as described. Could do with an easy to select 'dark Mode'. Use on S20Ultra with Samsung Dex giving the desktop apperance, seems identical to the PC in operation. Plays advert on exit of the app, no interuptions...
