Keyboard and trackpad not fully supported on iPad

I am using an iPad with the Magic Keyboard. When working with spreadsheets, you cannot scroll or zoom with the trackpad. Keyboard shortcuts don't work even though there is literally a page listing these shortcuts. As a productivity suite, the lack of such basic functions really makes me question how anyone can be productive with this app.

Still this annoyance.

Still with this new version, any created document is just named ‘blank’ and immediately launches the app. Still the icon is exactly the same so unless you change the file name yourself and it is clearly named you don’t know if it’s a text, spreadsheet or presentation file. Clearly the developers don’t read these reviews.

Fast and Functional

A Smooth experience with the whole functionality! I can open my files on Mac, Windows, Linux and can keep my workflow. Smooth!

Who needs excel

This works well

App crashes on Calc password files again

Agree with the others. The latest update killed use of Calc password protected files again. They crash as soon as you enter the password. This was broken recently in a previous update then subsequently corrected…but now broken again.

Good but needs improvement

To track my finances, I use LibreCalc on my Mac and Colabora Office on mobile so that I can update the spreadsheet I have on the go after making new transactions. I switched over from Excel a couple of months back and can’t complain when it comes to the basic function I use it for.

However I would like to suggest some quality life improvements. Firstly, I would like to see an easier way to switch horizontally between cells after inserting data into one cell. On excel mobile, there are left and right arrows above the keyboard when you type so that you can switch to the cells left and right of your current cell. I would also like to see stability updates for users on iOS 27. After I got a new phone i noticed that the border showing the current selected cell will sometimes glitch between two cells. Sometimes the glitch will fix itself but other times it won’t and I’ll have to click save and then go back into editing mode to continue working. I have also noticed that dragging the corner of the selected cell to select multiple cells will cause the sheet to scroll down uncontrollably which makes it impossible to consistently select multiple cells.

Presque Libreoffice

Libre office en version nul et buggé… à quand un vrai portage sur ipad???

Unreliable

App is crashing when opening calc docs after latest ios update. Running latest version and reinstallation didn't resolve it. Glad I have Libre office on mac to rely on. Wish Collabora could tighten things up.

Latest version issue

Can’t open password protected file. The app keeps crashing.

Constantly disconnecting

I was unable to open other apps on my phone without this app disconnecting from the server and deleting all of my progress.

So basically if you want to use this app you can forget about doing any research to help with your writing or responding to phone calls/texts because if you leave this app in the background it crashes.

Too buggy to use

I really want to support the app, but so many basic functions either don’t work at all, or bug out like crazy. I can’t undo with command, even though it says I can. I can’t crop pictures, I can’t add backgrounds, and the list is really growing. Do you need testers or something?

Until I Dump Apple For Linux Soon It Will Do.

My 34 year association with Apple will end soon when able to purchase a new laptop and migrate completely to Linux. I can’t nor will continue to allow myself to be increasingly locked into Apple’s high security electric fenced in prison yard for the sake of being a living bank account for the enrichment of their investors anymore. Nor buy the ongoing marketing lyes that it’s for my own security or that today’s version of Apple is ethically the same as it was twenty years ago. It hasn’t been for roughly fifteen years. Besides Linux is a more secure system than OSX.

That said over the past year Apple has quietly made it increasingly difficult to use third party apps. Apple wants to control the choices users make driving them to their weak and seldomly meaningfully updated native applications serving as nothing more than front doors to their subscription services , iCloud services, and online stores. Apple even changes their devices in ways to force their users into this. Consider the artificial changes Apple made to iBooks with their release of Catalina forcing iMac users to increase iCloud subscriptions or make the choice of no longer maintaining their own private libraries on their tiny but expensive internal drives. All the while subtly “re-educating” their loyal customers that it was a far better solution to buy from their online store.

So with the limitations this app must function as and most likely those to come as Apple reverts backwards to the era pre-Steve Jobs return when they ran Apple into the ground in the early nineties, i will deal with this.

Next year I trade this new iPhone in for an android or anything other than an other iPhone. I should have listened to my brother and friends when they made their exodus from Apples prison facility but noooooo. My stupidity.

Three decades and countless Apple products is enough.

Does what I needed - open encrypted .ODS spreadsheet from LibreOffice

No other app on my iPhone wanted to open my encrypted LibreOffice Calc file. Getting silly error messages like ’try again later’. Installed Collabora Office and it found all files it could open on my phone immediately. Entered file’s password and able to view it. Solved my issue. Whether I’d use it on my iOS device for any advanced editing… not so sure.

Loses your work and other unpredictable behaviour.

Continuously loses your work with no obvious way to save other than export whole document to another copy. Frequently pans thousands of rows or columns away for apparently no reason. Impossible to reliably drag cell selection past the cells in the current view.

Limited support for files with macros and buttons

This app allowed me to open and view most of my open office and libre office files. The spreadsheet it choked on contained macros and buttons.

Obviously I don’t know for certain why this file caused an error and aborted the load, but those are the differences between the files that worked, and those that did not. So, please try to find the bug and correct it. I cannot be the only one who uses these features of Libre 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.
