It’s essentially an open source fork of maps.me by the original creators.
I’ve been using OSMAnd for years, but it always felt laggy and not that reliable. Searching was slow and so on. Many street or things it didn’t instantly find.
In the Graphene App Store I jnust discovered Accrescent (another app store thing but only with like 10 apps - they’re all gold though, god damn)
An in there I found organic maps. And this shit is google maps level responsive. If you’re on the lookout for a google maps replacement - consider trying this.
Byeeee
You can actually contribute to it. There areso.me great mobile apps for this. I recommend Vespucci for in detail changes(creating new structures or editing their properties) and Street Complete for filling missing information.
