What's New in Collabora Office

25.04.9

March 4, 2026

Hi everyone - happy new year! Yes, I know it's March - but we've had a bit of a longer break than usual and I didn't get to tell you that yet :) In this version we've made some accessibility improvements - we hope the app should be much easier to use if you're using a screen reader now. We've also built this with fixes and features from Collabora Online 25.04.9. Finally, we're resuming our normal release schedule - the next version will be in around a month's time - thanks very much for using Collabora Office!

Adequate but no more

July 2026 - Still no fix to the Proton save issue.
If you can’t save a file, what really is the point of an office app? Now actively looking for an alternative.

March 2026 - Still no fix to the Proton save failure. Every other app manages it just fine. Until the save is reliable, the app is useless.

March 2026 - Not able to save files onto a Proton Drive. It suggests a save and changes the file information to the latest date but no actual data changes.

30 March 25 - For some reason, seems unable to load Open Document Format files saved from LIbre Office on Mac. Files simply greyed out.

Updates are few and far between. I’d almost call this abandonware. Libre Office (Linux, Mac) updates regularly and is always improving but Collabora seems to be static and set.
That said, it’s the best office app for iPad and doesn’t spy on you using it.
It is fiddly and can be difficult using a touch interface but once you get used to it, the app is basically OK. It should be much more and I’m looking forward to Libre finally porting the actual Office from Linux to iPadOS. Not holding my breath, though. In the meantime, this fills the gap.

Problems!!

Collabora Office is a great processor program, but I’m finding out if doesn’t work well with the newest Apple updates, such as 25.3. I will not allow you to highlight, select what want to change in the document’s that have been copied from the docx format, and changed to odt format. I am not a novice with this program. The instructions that AI gives to fix the issue do not help.

Excellent

Using this on an iPad Air I was able to view edit and save existing xlsx files that I have saved on Dropbox.
These files were originally made with Libre Office on Linux and the compatibility was 100%
Nice!

Can’t copy formulas

Nothing I can do will allow me to copy formulas on my IPad. I asked ChatGPT for help and after a half hour and several screen shoots I gave up after ChatGBT said it looks like a bug in the IPad verison

Great Potential but has problems

The biggest issue I have is the “disconnected from server” message and resultant unresponsive state. This happens even editing a local odt file.
Removing the app from memory and restarting seems to fix the problem.
It would be nice if the developers could fix this issue.
There are a few quirks which are annoying but once you figure out how to deal with them the app works well.
