Organic Maps (Unofficial)

That's fair enough, it's a lot of work to get the data filled in.

Apps like Street Complete gamify adding data though, which can make it more interesting. It will give you a quest, like asking for the building number on Oak Street, for example. It's the kind of thing that you can do for a few minutes while you're waiting for the bus, or your coffee, and helps to plug away at the gaps in the data.

Just be careful because it can be addictive, and before you know it, you're using the OSM tools and micromapping your town 😁
