Today I found out that it’s actually a lot easier to contribute to Open Street Map than I thought. There are some serious gaps in house addresses in my area and I was painstakingly using the built in browser editor in the browser.
But, you can use a FOSS app (available on fdroid) called StreetComplete that makes it a lot easier to help out filling in the gaps in your local map data.
It’s really fun - kind of like Pokémon Go but you are actually making an impact 😁
Maps.me and organicsmaps apps are great too to edit osm. You can also replace google maps and its navigator which is great because if you don’t find something on maps.me, you can immediately add it.
