It's called OpenStreetMap, the last character is P, it's singular.

For reviews there are multiple ongoing projects, none of them is mature enough for everyday use, they have a very few content:

• https://lib.reviews/
• https://mangrove.reviews/

There was a long and very interesting thread about this last year on the osm forum: https://community.openstreetmap.org/t/a-crowd-sourced-review-service-for-openstreetmap/136235/24

For timetables, it's an existing standard called GTFS, public transport companies should publish their timetables in this format. Transportr is a mature app which supports a lot of companies and cities: https://transportr.app/

CoMaps (a better fork of OrganicMaps) already have a lot of issues about integrating GTFS feeds, e.g. https://codeberg.org/comaps/comaps/issues/1651

i use öffi for public transportation, maybe there's something similar for your region? or maybe your region is already included, check here: https://oeffi.schildbach.de/

I'm usino this https://f-droid.org/packages/xyz.apiote.bimba.czwek it support external gtfs zip links. Hoping for future decision and integration in comaps

Transitious might be one of the best Open Source Routing right now. Used for example in: https://cartes.app/

All alternatives here are pretty good. Recently there was another app released its called Transportia. https://github.com/Wafler1/transportia. It has nice UI, but could be a bit buggy

Yeah that would be nice.
