This is what I use in my main GrapheneOS profile. I still have a dedicated profile for Google Maps though as I still have not been able to give up their greater datasets (i.e. traffic) in all cases.

Decent app though. I saw someone here mention proprietary code but I wouldn't worry about it, just install the F-Droid version. That's why I use F-Droid - to guarantee I don't get proprietary blobs.

Proprietary parts had been mentioned in the context of Organic Maps - their map generator is partially closed source, and even OM F-Droid build includes some proprietary assets.

In CoMaps we are serious about being 100% FOSS and this is one of the reasons we've forked from OM.

Don't worry, we have no proprietary code in all builds of CoMaps, not just F-Droid one :)

To be honest, I use Organic Maps over CoMaps simply because Organic Maps is available in Accrescent (which is in turn provided by the GrapheneOS App Store), and CoMaps is not. Both Google Play and F‐Droid are just enough of a hassle (and I mildly dislike both of them) to keep me on the map app that doesn’t require either one.

Magic Earth is fairly decent at traffic and dynamic routing. Worth the small subscription fee to keep them going, in my opinion.

HERE WeGo does traffic, if you want to ditch Google Maps.
