About the app:

Collabora Office for Android uses the same engine as LibreOffice for Windows, Mac, and Linux. This, combined with a new front-end based on Collabora Online, reads and saves documents similarly to LibreOffice desktop.

Collabora Engineers Skyler Grey, Tor Lillqvist, Tomaž Vajngerl, Michael Meeks, Miklos Vajna, Jan Holešovský, Mert Tümer and Rashesh Padia have been developing Android support since 2012, with the help of Google Summer of Code students Andrzej Hunt, Iain Billet and Kaishu Sahu.

Ratings and reviews

Perfect application for viewing and editing OpenDocument formats. A good companion app with Nextcloud for editing remote documents. I took stars off because I couldn't find a fit-to-screen view like in Word or Google Docs (I'll keep looking). Also, selecting blocks of text hides the keyboard rather than opening a "right-click" menu, making it difficult to edit. Finally, I'd like to easily move documents written on my phone to my Nextcloud.

This is the best editor for LibreOffice documents on mobile. On a tablet, it looks and works alright, though on a phone, the interaction with the app (buttons, navigation, etc.) becomes more confusing. If you are working on a text document, several major obstacles persist: there is no option to fit the text on your screen, so you have to scroll left and right to read a sentence; selecting text is janky and you can't easily copy-paste. No auto dark mode, no ability to connect to cloud storage.

Works, but it's pretty buggy. Even when editing local files, I often get "server disconnected" if I switch to another app for more than a couple of seconds. Sometimes it stops accepting any inputs, and so I can't edit anything in a spreadsheet. The only workaround is to close that sheet and reopen it. Also, the dropdown selector in spreadsheets is too small, and zooming in doesn't increase the size, and thus it's very hard to press it.

What’s new

Hi everyone! We've got a few mobile-specific fixes and improvements this time around - focused on phones. In particular, we've tuned keyboard popups and zooming, and continued to work on our improved search bar.

This'll be our last mobile release this year. Happy holidays; I hope you have a great rest of 2025 and a wonderful new year!

As always, you can find the code that was used to build this release on our GitHub: this mobile release is based on code from Collabora Online 25.04.7
