About the app:

Collabora Office for iOS uses the same engine as LibreOffice for macOS and other platforms. This, combined with a new front-end based on Collabora Online, reads and saves documents similarly to LibreOffice desktop.

Collabora Engineers Tor Lillqvist, Tomaž Vajngerl, Michael Meeks, Miklos Vajna and Jan Holešovský have been developing iOS support since 2012, with the help of Google Summer of Code students Andrzej Hunt, Iain Billet and Kaishu Sahu.

Good Word Processor

I’ve been using this for a while to write on my iPad, and it’s been working fine for me. The biggest issue I have is that the UI is very bright and I don’t think there’s an option to use dark mode - it’s very shocking to the ol’ eyeballs when the rest of the system UI is dark, then your word file opens with the blinding brightness of the sun.

A dark mode would be absolutely fantastic, honestly.

Closest thing to Open/Libreoffice

It may not have bells and whistles but this is by far the closest thing you will find to open/libreoffice on iOS or iPadOS.

I keep my iPad Pro (2017 version) in a laptop shell with a trackpad and keyboard and this app feels very natural when editing spreadsheets and documents. It does take some getting used to coming from an actual desktop / laptop but you can legitimately use this as a replacement if you have a hardware keyboard attached.

Only hang up is the awkwardness with the spreadsheets where the keyboard will only start working (arrow keys) after you have started to edit a cell. I think this is some weird focusing issue though and is easily to get past mentally.

Overall it is probably the best thing you will find that supports saving in open formats (odt etc) on an iDevice. Thank you so much to the developer because any alternatives I have tried before this were either riddled with ads, required a subscription, or didn’t support the files from libreoffice. Minor touch ups would make this the best office suite alternative to MS Office but all of that is mostly cosmetic.

Best iOS spreadsheet and office suite (short of the costly MS office apps)

Thanks Collabora for finally creating an IOS office suite app that rivals the MS suite with both quality and Windows file compatibility, but for free! (My accountant also thanks you!!)

A very few minor bugs, all of which I've been able to work-around. I'm sure they will be fixed sometime soon, as it is so obvious that a lot of time, care, and talent has gone into the crafting of this excellent app, and with so many very recent updates too.

Note to a dissatisfied rater: To move the toolbar off of the first rows of the spreadsheet, just click on the "edit" icon, which is a pencil in the lower right.

To the folks at Collabora: May you and this most excellent app live long and prosper! Where can I send a donation?
