It uses crowd-sourced OpenStreetMap data and is developed with love by MapsWithMe (MapsMe) founders and our community. No ads, no tracking, no data collection, no crapware.

This is a tried and tested platform that works great, led by people who know their stuff and care deeply about the user. Please donate if you like it: https://github.com/organicmaps/organicmaps
I've been using it and it is great.
It's open source, development is very active, and there's much more of a focus on user experience (2/3 of the pinned issues).
Though it does notably lack public transportation routing.
"Organic Maps is pure and organic, made with love: Respects your privacy ; Saves your battery ; No unexpected mobile data charges"
And OpenSource: https://github.com/organicmaps/organicmaps
But the "usable review integration" is not a solved problem yet.
