Not rn. I was gifted these. For what I know, the ORG gives them in their events. I was told that maybe in the future people will be able to buy them.
edit: I am promoting Kiwix heavily in my region, soon I’ll be giving away some to people I’ll help install Kiwix.
Damn, that’s weird. I’ve been using the Play Store Version and is kept up to date.
I think the Fdroid version is not being promoted anymore. Certainly should be updated in f-droid for people who use de-googled phones.
