Navi

Offline-first navigation with terrain-aware eco routing
Version: 0.3.30-beta
Added: 16-10-2026
Updated: 04-11-2026

Navi is an offline-first navigation app. Download map data once, then plan and follow routes on the device without needing the internet for every trip.


Before first use: Navi does not come with a ready-made routing database, unlike many commercial navigation devices whose maker ships precomputed maps. Open the Tools menu and use Download region to get your region. Navi then downloads the map data and builds its routing and search databases on the device. This takes about 5 to 22 minutes per region depending on its size, for example about 5 minutes for a small country like Luxembourg and 20 to 22 minutes for a large region like Østlandet on a mid-range tablet. Route planning does not work until this is finished.


Travel modes include car, bicycle, e-bike, hiking, motorcycle, truck, and motorhome. Optional vehicle size limits skip roads that are too tight. Avoidances cover motorways and fast expressways, tolls, and ferries.


Eco routing prefers gentler, less energy-hungry roads by taking hills into account. Hiking and cycling can optionally prefer marked long-distance and pilgrim-style trails, with normal paths used when a marked trail has a gap.


Download a region (OpenStreetMap extract), an offline basemap, and optional elevation/terrain data in Tools. A background indexing job builds compact routing packs so later plans are fast; you can still plan while indexing runs. Map updates are never silent — only when you ask.


On the road:



  • Place search, From / Via / To, GPS fill, map mark and saved places

  • Off-route detection and reroute

  • Break and rest suggestions, including truck driving-time rules where known

  • Drive bars with altitude and trip ETA

  • GPS follow, and north-up / compass / direction-of-travel map rotation

  • Optional experimental 3D hill shading and map tilt


Navi is free and open source (GPL-3.0-or-later). There are no ads and no tracking. Network use is for downloads and updates you choose — not for silent data collection.
