Organic Maps is the best open source Maps App I've ever tried
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.
so i opened this app for the first time just now and entered my address, but it only went to my street. when i tap my house, it just says "building".. is there no residential support?
Depends in where you live. For instance in Germany house numbers are associated with the building but in France house numbers are their own object. The Idea there being that one should map the location where the plate with the houseumber is, and not the building(s) its associated with. If you dig throug osm map forums or issue trackers you'll find the dispute resurfacing every now and then.
