Everything #OpenStreetMap related is welcome: software releases, showing of your work, questions about how to tag something, as long as it has to do with OpenStreetMap or OpenStreetMap-related software.
OpenStreetMap is a map of the world, created by people like you and free to use under an open license.
Join OpenStreetMap and start mapping: https://www.openstreetmap.org.
There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community
https://mapcomplete.org is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
I first learned of Street-Complete here and I really like it.
It's satisfying to walk around, complete little tasks, and get prizes, scratching a similar itch to Pokemon Go.
Stuck waiting for someone? Add opening hours for a few local businesses.
Have a long walk ahead of you? See if you can add/check house addresses as fast as you can walk.
Want to walk off a few beers before heading home? Complete some tasks in the bar street.
Its a very constructive way to "be right" on the internet.
Why does F-Droid tell me that the app has features that I may not like?
It is because it has what F-Droid considers anti-features. In this case, even tho the code is open source, it seems to require a non-libre dependency to measure distances. See https://gitlab.com/fdroid/fdroiddata/-/issues/2627 and https://github.com/streetcomplete/StreetComplete/pull/3709#issuecomment-1039710672.
F-Droid is very strict with what it considers an anti-feature, and Android is very restrictive to properly work without at least one closed source library (thanks, Google), so I say you can ignore this, but it depends on you.
Also, openstreetmap itself is a centralized eco system, even though you could theoreticallly host one yourself.
