Works, kinda, but broken. Opened an ODT file, and everything worked perfectly. Wrote about two pages into it, saved it. Found the save was name (Invalid).ODT instead of the old filename. Tried to open it with with Word for Android, and it's corrupt. Reopened it with this, and it lost all formatting (paragraphs) in the application that wrote it. Renamed it and tried again after treating, and Word still won't open it (says it's corrupt), though this app can still see the text. Please fix!

I'm so sorry to hear you spent so much time editing your document only to end up in such a situation. Would you be able to share the corrupted file with us? That might give us a clue what went wrong. You can reach us at

I've been using libre for years on my PC and just re-downloaded the app to edit and sign an official application and the download file option does not work. Opening the edited file from one drive removes all previously applied text to the appropriate boxes. I see no option to create a signature and apply it, which was one of its greatest features and only reason I would recommend this over any other pdf editor. I have no idea when you changed but you guys messed up a good product

Why do some people people rate crappy aps so highly. This app is a dog. Its almost impossible to use. They are desperately trying to monetize it and its just horrible. I have a large Android Note 8 and I can hardly see the document with all the incessant popups, ads, support popups etc. If the developers read this. Have a look at your product. Try to use it. You'll see what I mean.

Thanks for your feedback! There should definitely be no popups that obscure the document. Would you be so kind and send us a screenshot to I'd love to publish a new version that addresses your complaints soon.
