Great Open-source map. Fast and effective. I use it all the time

If you listen to the CoMaps developers’ perspective, they’re naturally going to talk up their competitors at Organic Maps. In any case, Organic Maps another open-source map, free and open to everyone. And new features are added much faster than in CoMaps (public transportation, hiking style, alternative routing). Try both options and choose the one that works best for you.

Organic Maps for Android and iOS shows defibrilators on map. Just search for “aed”.

You should try Organic Maps which is original app forked by CoMaps. Organic Maps has better UI, shows public transport routes, shows alternative routes and a lot more. Give it a chance.
