Sorry for spamming, but seeing that the other OSM-post got quite some traction, I wanted to point out that the OSM-community here is coming to life as well.
OSMAnd has literally saved my life when my Garmin died and my hiking buddy's phone also died and I remembered I had saved off-line maps for the state we were in and could traveling-salesman our way out of the mountains safely.
That’s its strength and its weakness imo; the UI is not as clear as the Organic Maps’, and it feels relatively cluttered.
Also, Organic is both gratis and libre, while OsmAnd is subscription based on iOS. It is a one time purchase on Android though, but that still means the full app isn’t gratis.
I don’t mind paying for an app, but fuck subscriptions. It’s dirt cheap and all, but I still won’t pay for it.
I’ll have a look at Organic though, that sounds right up my alley. If it’s open source, I can even have a look at raising a PR or two to pay them back.
Organic Maps is indeed open source and available through f-droid/GitHub/Telegram.
It's actively developed and it's UI is more easier to use than OSMAnd. The search accuracy is also way better than in OSMAnd, in which I often can't find places.
