If by "this" you mean the jerboa app, it is on F-Droid. Both in the official repo and on Izzy's.

jtx board - Journals, notes, tasks

OpenTracks - Sports tracker

Öffi - Public transport navigator

ViMusic - Listen to music from YouTube

Open a feature request on github. You might get lucky.

Wikipedia is a great place for general knowledge and I don't wanna change that. What I'm looking for is a way to create wiki for a very specific topic, which could be attached to a lemmy community about that topic.

For example having a lemmy community about a certain programming language with a wiki containing documentation about that programming language. This isn't something you'd put into Wikipedia.

You probably need to re-install it selecting the Izzy repo. The app in the offical repo is signed differently from the one on Izzys and the F-Droid app will stay on the repo your app is installed from.

Izzy repo usually updates daily while official one is always a few days behind.

Edit: you might wanna get Droid-ify to have a better F-Droid experience.

Yes, I'm thinking more of a place to collect technical documentation / tutorials. No body wants to create a place of "alternative facts" in the fediverse.

jtx board for tasks and notes

sadly OSM just doesn't have a usably complete business directory where I live

Its up to you to change that to the better

Or use fdroid with izzy's repo. Link is in the github page as well.
