OsmAnd
A powerful offline maps and navigation app built on OpenStreetMap, developed by a company in the Netherlands. Detailed offline maps, hiking and cycling routes, and deep customisation, all without tracking where you go.
Quick facts
Downloaded regional maps work completely offline, including hiking and cycling routes, contour lines and points of interest – handy in areas with no signal. Deep customisation lets you toggle exactly which map layers and details you see.
The interface is dense with menus and settings compared to Google Maps' single search box, and live traffic data is thinner outside busy Western European routes.
Why does it score 100?
Incorporated in Amsterdam, Netherlands – a full EU member state.
Independently owned by OsmAnd B.V., with no outside investors or parent company.
OsmAnd runs its own infrastructure in the Netherlands, and offline maps mean most of your usage never touches a server at all.
The core app is open source, but the paid App Store/Play Store build adds some proprietary features, so it's only partially open source overall.
