OsmAnd

OsmAnd is the power-user’s OpenStreetMap app, packed with offline maps, detailed routing profiles, and more settings than any rival. It works entirely offline once maps are downloaded, keeps your movements on your device, and offers an open-source build on F-Droid alongside the store versions. That depth comes at the cost of a busier interface that can overwhelm newcomers and the free tier caps you at a handful of map downloads. Serious hikers, cyclists, and travelers who want fine control will find the most to like here. Unlimited downloads and extras require the paid OsmAnd+ or a Pro subscription.
