Atlasys is a privacy-first, open-source map application built with React Native and Expo. It gives you offline maps, 3D cities, smart routing, and point-of-interest discovery — without selling your data, showing you ads, or tracking your movements.
Map data comes from OpenStreetMap under the ODbL license. Routing is powered by OSRM. No proprietary map APIs. No hidden trackers.
Important
The Android APK releases on June 1, 2026. iOS support is planned shortly after.
