Good Commercial Office Alternative but

As a free (and open-source software I believe?) alternative to all the commercial office suites, OnlyOffice does a good job. I do suggest that the app maker and offer better integration with the Files app and include into their menu the ability to open files that are not already saved into the application, similar to the “open local file” option on the Mac version. All in all, thank you and keep up the good work.

Spreadsheet crashed and loss all data in the file

It is very unstable. I start to use this cross-platform office alternative because I have windows PC in the office, Ubuntu PC at home and a ubuntu laptop in the cleanroom. I record all my experiments processes and results in a spreadsheet. Then, it crashed yesterday when I tried to use this app in my iphone. The worst thing is that even I am sure I saved it each time when I finished it and reopened the file when i wanted to modify it (of course, because I work in 3 different computers and an iphone). After it crashed, everything went to zero. The file is restored to its original version which is empty when I create it on 9/3. Interesting, why shouldn’t it simply be the most recent version. That should be most straightforward. The data is really really important for me, and it takes another 3 days to measure it. It can be a general bug for recent onlyoffice software or only a bug of this iOS version app. But anyway, I will not use it any more. It is really a disaster. This is the first time I want to give a zero star.

Hopeful, but needs fixing

This app absolutely has potential, it’s promising, but it has a few things to fix.

First of all, I was hoping to replace both Google Docs and Microsoft Word app with this one because it was featured in an article that it has a better privacy policy than Google, but it is not optimized for mobile. It shows me the desktop-like version with tiny letters, despite being a mobile app version. The Microsoft Word Mobile app, for example, has a “Mobile View” option in its settings; OnlyOffice can possibly adapt that feature into its app.
