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
The version you linked on github is FOSS but it is out of date— newer versions on the play store are proprietary. Organic Maps is a continuation of the FOSS version by the original developers.
It is not. It used to be, but it got acquired by a third party company and became closed source and started tracking its users.
The good news is that the original developers of Maps.Me developed an Open Source fork of the original app: Organic Maps which is an excellent app that is actively developed by a team that listens to the users needs and is therefore constantly improving. I recommend everyone to check it out.
