Initial review

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.

Update 10/28/26
The last time I used this was about 11 months ago. And I was preparing for my long trip so I checked it out and was surprised to see that it has mouse support. I was able to use my Logitech MX Vertical mouse via bluetooth. I use LibreOffice Spreadsheet files (.ods) and it works perfectly fine, and one file contains more than a dozen sheets. I transfer files between the iPad and home PC via the cloud. Great. Love this app. More power to you guys.

Horrible app

Most useless app for mobile. Doesn’t select text there’s no way to copy it, text goes off the page and there are no page margins and the format is desktop only. This should not be in the Apple Store! What a waste of time . Highly disappointed with LibreOffice for putting this thing out

Great Productivity Tool!

I do quite a bit of writing using LibreOffice, which doesn’t have an iOS/iPadOS version, and this is a fantastic tool to continue my work on my iPad when I’m away from my Mac. Only issue keeping me from giving it five stars is the lack of touchpad scrolling support. Not being able to scroll using my iPad keyboard’s touchpad is a pretty big annoyance. If that was fixed, I’d up my review to five stars easily!

Disappointed with update

It seems that we lost the page setup in calc. Ant orientate spreed sheet from portrait
to llandsape.

Lost all my work due to “disconnected from server” error

Got a “Disconnected from server” error, which froze the editor, never went away, and caused me to lose hours of work. Why is this program connecting to a server? Why doesn’t it let you save your work while it’s doing this? Why does it force-lock the app while it’s reconnecting? Everything about this is an infuriating waste of time.

App broken: Constant crashes & loss of work.

I don’t know what happened with the last update, but the app is now entirely broken and unusable. It crashes often, throwing up a pop-up that says “Reconnecting” despite it being an offline app. The pop-up gets stuck as it never actually reconnects to whatever it’s trying to connect to. Whatever work I was working on is lost. The crashes are constant and unavoidable.

Sheets….

First couldn’t figure out why I half the buttons didn’t work. Have to be in edit mode. Then when I would try to access the sheet settings menu by long pressing the sheet, it would immediately select duplicate. Occasionally you can slide your thumb around and then let go. But not always. attempting to delete them, I had about 16 duplicates before I finally quit. Three stars cause the other stuff probably works.

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.
