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
I second magic earth for driving. The only reason I haven't entirely removed Google maps from my phone yet is because magic earth doesn't have data on business hours. This is the last killer feature I'm waiting for.
In the meantime I'm routing for any open source map that can do live traffic and business info.
I use gmap wv for that. It's just the web view of google maps but works better than Firefox and easier to pull up when osm fails. Navigation obviously doesn't work but should satisfy your use case.
Could just use yelp or a browser for business hours.
