I use Organic Maps. OsmAnd is also pretty good.

Organic Maps and Magic Earth are awesome. The best I've had so far. Magic Earth is more optimized for driving, though if that is what you're looking for.

I love Organic Maps, it is clean, simple, and works for 95% of my needs. The rest of the times I resort to OsmAnd, which is heavier and more complicated but has many more options.

The house number search can be tricky with OpenStreetMap based apps, unfortunatey, but still better than using Google, in my opinion.

I used Magic Earth in the past, but it has some wrong information in my city (an important road is marked as closed and it calculates long detours) which is not coming from OpenStreetMap, so I personally don't trust it.

I don't think the data is there for most house numbers. Everywhere I go, Street Complete is asking me for house numbers.

OSMAnd uses Open Street Maps data for it's map, so the product can be mature but the data is not for the area you were navigating.

I've been on a crusade to fill the holes in the data for the places I go, including house and business numbers using OpenStreetMap. If everyone were to do this for the places they go, we'd have all the addresses filled in and more!

TIL there are multiple open street map apps (obvious that there would be now I think about it!)

Clearly I have nothing to add, but thanks for asking the question, I'll be saving the post and trying out all the answers!

I used Magic Earth only two times but it worked really great and the Speed Camera indicator is a plus

My favorite app ever, not just mapping apps is Locus.

It justbdoes everything I need when I am outside.

The name is cringeworthy, but Magic Earth is a very good piece of software.

seems to have trouble with navigating for bicycles, but otherwise it’s good.

Specifically for motorcycles, I’ve come to very much appreciate Go Ride that’s made by TomTom, I believe.

OSMAnd has a UI made in hell, so i understand why you would be looking for an alternative.

Well, if OpenStreetMap doesnt have the house or building number at all you will need to add them. If the numbers are their then try searching by (city streetname building number). Example would look like "Atlanta Amber Road Northwest 3733". If the building number doesnt exist in the OSM database try gps-coordinates.net and enter the address. Once you get the coordinates plug those into OsmAnd (i think it will only take the first 5 numbers after the "." So 32.12345678 would have to be entered as 32.12345

OsmAnd is a favorite of mine. If you live in one of the covered areas (North America for sure) OpenSuperMaps merges a US style address search and most street addresses into the maps.

OsmAnd search goes by town, street, number while these maps work with "25 oak street Chicago Illinois". Also, the open street maps rely on croud sharing for map details, so many areas have very little detail, while others put Google Maps to shame.

For navigation, I like Magic Earth. It includes similar search ability and has Waze-like features. The only problem is a lack of critical mass of users to get good traffic and hazard warnings. You can be one more user to supply such info.

This dev in the link gathers address data and inserts it into map obf files. You download each one you need then you put the obf file in osmands android data directory where your map files usually go. There's also an app called addresstogps that allows you to lookup an address and it converts it into gps coordinates and allows you to open it in any map app. However addresstogps uses Google as a back end. Ive found that dev in the links address lookup to be so robust, there's almost never a time when I need to use a different address lookup.
