@ploum @organicmaps @peertube Organic Maps is amazing because it works fully offline. And OSM is great in general because of all the small things that are marked there. There's a single small water fountain beyond security at the Hamburg Airport, and it's tucked away on a separate floor so you'll only see it if you happen to go to one of the few gates there (I assume the shops that sell water in plastic bottles lobbied for this). But OSM has it, as well as the gates, defibrillators & more!
