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. ### 2/5 — Problems!! *2026-07-18, version 25.04.9* 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. ### 5/5 — Excellent *2026-07-10, version 25.04.9* 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 These files were originally made with Libre Office on Linux and the compatibility was 100% Nice! ### 3/5 — Can’t copy formulas *2026-07-10, version 25.04.9* 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 ### 3/5 — Great Potential but has problems *2026-07-04, version 25.04.9* 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. ### 2/5 — Not sure about this one *2026-07-01, version 25.04.9* looking for replacement for SmartOffice, not on App Store any longer. Drawn to this app through the open source MS office alternative Libre office website as a way of reading their documents on an iPad. Also a fan of the privacy policy - apparently not gathering any information. However, as soon as I opened the app, it went directly to my Files folder, trying to access everything I had in there. Documents I wanted to open in SmartOffice were stored in SmartOffice or were accessed such as dropbox. It did not go searching my iPad for anything it could open. Ultimately not sure about this privacy claim. deleted the app. ### 4/5 — Initial review *2026-06-24, version 25.04.9* I’m also surprised why this has such a low rating. So I tried Opendocument Reader and OOreader. Both were terrible with the latter worse (viewer only, no editor) than the former (viewer and editor). Collabora Office displays the spreadsheet correctly with tab names or correct order, highlighted tabs display correctly, split screens also. I downloaded this to mainly view my ODS files while traveling but I might venture to do some editing and see how this app works. So far it’s great. ### 3/5 — Looking forward to using it, but… *2026-06-21, version 25.04.9* If LibreOffice were ever to go defunct, Collabora will be my goto. It’s open source and integrates with my Nextcloud. A few problems though with the mobile version: • copy and paste functions have an intrusive menu that eats up the screen, not the standard “right-click” pop-up. • no “mobile view” option; stuck in page view. ### 5/5 — A powerful tool as good as any other *2026-06-11, version 25.04.9* Our company just transitioned away from 365, and this seems to be a very worthy successor. It does everything I need, and is well designed. Overall things look great so far! ### 3/5 — Handwerklich ganz gut gemacht... *2026-05-30, version 25.04.9* ...aber für's iPhone ist und bleibt Microsoft Office leider unerreicht! Allein die kompakte Ansicht, die das Bearbeiten von DOCX-Dateien auf kleineren Geräten ungemein erleichtert, ist beim "Original" einfach unerreicht! Manche Office-Apps (z. B. MobiOffice) übernehmen ja nicht einmal das aktuelle dynamische Datum in einem Schreiben. Das kann Collabora-Office exzellent! Diese Datums-Übernahme setzt Polaris-Office auch sauber um und zeigt zudem sogar Schriften mit einem Schatten korrekt an! Leider fehlt auch hier eine kompakte mobile Ansicht! Ich würde diese Collabora-Office-App daher eher für das iPad empfehlen... ## Frequently asked questions about Collabora Office ### What does Collabora Office do?
