Collabora Office for iOS: Unfinished open source productivity suite

Collabora Office is a promising mobile open source document editing suite based on LibraOffice. There are versions for iOS, tested here, and Android.

At the time of writing, Collabora Office Version 6.4.8 for iOS is not ready for everyday use.

Collabora Office for iOS

At a glance:

For: Free, open source productivity suite for iOS and Android. Plenty of features. Compatible with Microsoft Office and Open Document Format.
Against: Unfinished, bug-ridden, unstable, user interface jars with iOS.
Maybe: Has potential to be fine if Collabora is able to fix up the problems.
Verdict: Avoid for now, worth watching for future improvements.
Rating: 1 star out of a possible 5.
Price: Free.
Web: Collabora Office.


Collabora is a UK-based private company specialising in open source software. The business sells support and services based on LibreOffice. Collabora Office is, in effect, a version of LibreOffice for iOS and Android.

The software comes with plenty of features. You can create and edit text documents, spreadsheets and presentation.

Collabora Office can open and save in a variety of open document formats along with Microsoft proprietary formats. It will also open PDFs. If you open, say, a Microsoft Word document, you can review or edit and return the finished work to a Microsoft Office user.

For this review I tested Collabora Office on a 12.9-inch 2020 iPad Pro with a Smart Keyboard Folio and a 2020 iPhone 12.


When reviewing a product like Collabora Office, I like to use the software to write the review. This proved impractical. That tells you everything you need to know about the current state of Collaborate Office.

There is a lot wrong with the user interface on iOS. It doesn’t take long to go down a user interface dead end.

While attempting to write this review, again and again I found I had to shut the app, remove it from the iPad’s memory and start again from scratch. In the end, I gave up.

In a way this review feels more like writing a bug report for the developers.

Beta if you are lucky

Collabora doesn’t describe the software as beta. That would have helped, but even beta is generous. This is more an alpha version of an app that’s in development. To be fair, the Collabora Office App Store Preview makes it clear the program is in development.

It would be possible to write many pages about the problems encountered during the review. To keep things short, let’s look at one area:

You load Collabora Office in the normal iPad way by touching the app icon on one of the home screens. This takes you to a Files-like display where you can see folders in a sidebar and any recent documents that are in compatible file formats.

Not iPad-like

If you then chose a document, you’ll see a non-iPad-like loading screen with tiny text telling you the document is loading and a progress bar. The document opens in a read view.

Departing from iPad-like conventions is fine. The iOS version of Microsoft Office does this at times. But Collabora Office looks like it has been ported from a PC and left in that state. Microsoft managed to add iOS polish to its version of Office.

Before you can edit the document, you have to find and select the pencil icon that shows up in the bottom right corner of the display. There’s no user interface continuity here. It feels like you are jerking from one user interface design to another.

Mac style menu bar

Across the top of the display there are dropdown menu items like you’d see on a Mac or PC. To the right of these is a Collabora Office icon that looks as if it may have a function, but it doesn’t do anything.

The document shows centred in what applications like Microsoft Word describe as a page view.

There’s a ruler across the top of the page. Above the ruler the document name shows… but in the case of my test document, I can only see the first four characters of the name, the rest is hidden. Presumably it is behind something.

This makes for a crowded space. It would be fine on a Mac or PC. It’s something you could live with on a large screen iPad. On smaller screens it is cramped and cluttered.

It feels like you can select this and, maybe edit the document name. It blinks if you try selecting the name, but nothing else happens.

Tiny characters

At the bottom of this display is a search box. The word ‘search’ is printed in tiny, faint characters. Next to that a box tell you this is page 1 of 1. And there’s a language indicator. In my case telling me the document is in New Zealand English.

It’s possible to use the iPad stretch gesture to make the document bigger for a closer look. However, stretching is not smooth, the screen adjustment is jarring. And after a while, without touching the display, the page display got smaller and moved to the left of the screen.

The only way to get the page display back to full-width was to close and reset the app.

Dead ends

The first time I clicked the pencil icon to edit the document, I saw an empty screen. It may be possible to get back to the previous screen, but if it is, it is not obvious.

At this point I had to close the app and clear it from memory yet again. You have to go all the way through the document opening steps again.

The second attempt with the pencil icon opened the document in an editing screen. This problem with documents not always opening as expected happen again and again during in my review.

There’s a worrying instability here. During the review there were a few times where something would work, then not work later.

Resembles LibreOffice

Collabora Office’s editing screen resembles LibreOffice or Microsoft Word. There’s a ribbon across the top of the document and a menu row above. The ribbon changes function as you move from one menu item to another.

Editing works as you’d expect. You can move around the page using cursor keys or the touch screen. Selecting text is a hit and miss affair. A long press on the touch screen can select a word, but this didn’t work for me every time.

I had more success using the keyboard cursor keys and then the shift key to select a string of text.


Having said that, there were times when the cursor key movements didn’t line up with text. Again this was unstable.

Collabora Office had difficulty when I tried using the Apple Pencil. At one point it deleted text as I moved the Pencil.

In practice I found the software struggled to display certain documents. In a few cases the lines of characters overlapped with each other making them hard to read on screen. At times the page display seemed to break down altogether.

Another problem area was documents could get lost when saving.

Other iPad writing apps are smooth. This is not. The dialog boxes that appear are crude looking. Collabora hasn’t paid much attention to making things look good.


Investigate Collabora Office by all means. It’s a work in progress and you can expect it to improve over time.

By the time you read this is may have moved on from version 6.4.8. The version history suggests the developers update the app every month.

That said, Collabora Office is unusable for day to day work at this stage.

If you want an iOS productivity suite and you can’t bring yourself to use Microsoft Office, you have options. There’s Google’s Workspace. Or you could stay with Apple’s iWorks apps. Pages, Numbers and Keynote will get the job done. There are plenty of other options for people who want to write on an iPad.
