Hello, I'm trying to understand if maps.me is open source or not, as on the web there are different contrasting informations. Here is stated that it is, but here is stated the exact opposite
That's a tricky question and I feel like the answer is very personal. Simplifying it too much:
Organic Maps: basic, simple, easy to set up and understand.
OsmAnd: heavy, complicated and with looots of information.
I personally find that Organic Maps works for 90% of my needs: it's easy to use and navigate through. The remaining 10% I need more advanced functions not present in Organic Maps and OsmAnd comes to the rescue.
I personally find OsmAnd better than Google Maps, except for the lack of traffic alerts, public transit navigation and streetview (Mapillary streetview works fine... but it was bought out by Facebook 🤧).
I also use it as my bike computer due to the really handy widgets
