Edit: the app seems to be pretty old, I like the Writer editing more (it works) but for other things, CollaboraOffice is way better.
Has anyone tried that on a tablet? The phone UI has like no features
Currently it is a “viewer” (renderer with usable UI) and editing features are experimental.
They only release their APK to Google Play for whatever reason, but you can use F-Droid to get it
Bugs can normally be reported to their bugtracker and you can join their forum for more community support!
Downside: the editing features are VERY rudimentary, while the app is only about 50MB (⅕) smaller than Collabora-Office, which has better features overall.
Hopefully the editing portion takes off. Been using open document reader from fdroid to view and just been editing the actual ods files and such on my computer. Can’t wait to see what the future has in store
