Android

Try OrganicMaps (https://organicmaps.app) on Android. It's awesome!

https://www.openstreetmap.org/

It's the only one I know, I've also done mapping for them and updating several places around my home town.

Almost all alternatives use OpenStreetMaps. I prefer Magic Earth but all of them are similar enough

The main issue is OSM. They lack many addresses (varies A LOT among different countries, some are fine) and POIs. Please consider contributing yourself, because it depends only on volunteers!

It is SUPER easy. Just download StreetComplete on Android to add multiple different info in a very easy way (or just house numbers which are the most important info) and EveryDoor for POI editing/deletion/addition in just a few clicks. And don't worry if you don't input something because you aren't sure as long as what you enter is correct

OrganicMaps, love it

Osmand with some of these custom maps that add address data to the normal maps. It works amazingly and is also entirely offline.

For walking nothing beats OpenStreetMap. Absolutely destroys Google maps as it knows all the footpaths and what is and isn't walkable.

For driving I'm stuck with Google due to Android Auto.

For finding businesses etc Here is the best alternative but frankly Google is in a different league in this regard, nothing beats it.

I use OsmAnd~ it's very nice ,and open source . Oh and if you use the F-droid version you got the pro feature .

openstreetmaps.org ecosystem

for navigation I use Organic Maps: https://f-droid.org/en/packages/app.organicmaps/

I like OsmAnd too, but it's too much for most of my use cases. I still use it for recording trips.

I use Open Street Maps. There are multiple clients available, but the one I use is called OSMAnd+. It pretty much works just as well as Google Maps in my experience.

The FOSS ones suck in comparison honestly. There's really just osmAnd that has a really ancient UI. As for other OSM(OpenStreetMaps), I find MAPS.ME to be the best, but it's closed source with some crypto scam crap built in that you can't disable.

I don't really like OSM based maps because they miss tons of places where I'm at, when I specifically need building numbers and locations. Also the search on both apps is god awful and straight broken.

Google Maps is definitely miles ahead of the competition here. The other features like seeing how busy businesses are, reviews/images, menu and phone number/website. These are also icing on top of the cake that make it essential to have which none of the competition have, let alone any FOSS ones.

Open Street Maps. It has some gaps or missed addresses/neighborhoods/roads because it is built on contributions of volunteers.

I like OsmAnd as a client for using open street maps. I hadn't heard of organic maps though which someone else mentioned- I'll have to give it a try!

I use Organic Maps on my degoogled pixel. Does not have quite as much data as google maps, but works really well for navigation and uses openstreetmaps' data.

Organic Maps. It uses OpenStreetMap as a backend, plus it has hiking trails as well.

OpenStreetMap. Google Maps is probably the best product in the field tho, even among paid solutions.

magic earth for regular use and herewego if openstreetmap doesn't have data and I'm in a hurry

both are proprietary but way better than google

I also input data in openstreetmap if it doesn't have it from gmaps webview(by divestos) so I can use it in future without relying on proprietary services

Magic Earth (not FOSS), such an underrated app

FOSS turn-by-turn is unfortunately not great. I like the proprietary app HERE, because it works well for turn-by-turn, is based in Europe and has a privacy policy that fits on one page

None. Tried a few, none of them come close to what Google Maps offer.

maps.me has been pretty good - they occasionally try various ways of monetizing it (the most recent one seems to be some kind of limit on map downloads) but it was a pretty straightforward OSM viewer with basic routing and searching.

@AlmightySnoo with Traffic Data you can use #MagicEarth. It use #OpenStreetMap Data.

All the alternatives have poor search functions e.g. fuzzy search. After trying them all I use magic earth but will often find I have to get addresses out of google maps then put them into ME

I live in south korea, and unfortunately, openstreetmap isn't enough for daily usage on here. So I am using both. Google Maps(using GMaps WV) and organic maps

Similar question, but what's the best app for following a gpx track? Like just plot it on a map with my current location centered

For hiking and walking around the city open street map is great. I personally use mapy.cz - they work great and at least in central Europe - more accurate than google.
