A free, open-source trail companion that works where the signal doesn't.
Currently in alpha testing on Android. Built in the open.
Inukshuk turns your own georeferenced PDF maps into a live navigation tool — no data plan, no account, no servers watching where you go.
Import georeferenced PDF maps and see your live GPS position right on them — park maps, topo sheets, ski trails, anything.
Everything runs on-device. An OpenStreetMap base layer fills in when you wander off the edge of your map.
See the landscape around you in true 3D relief, with your trails and route draped over the mountains.
Track live time, distance and elevation gain/loss. Save and share every outing as a standard GPX file.
Every recorded trail gets a pace-and-grade profile you can scrub through, with notes and photos along the way.
Your location never leaves your phone. No analytics, no ads, no account. Read the privacy policy →
Open the app and grant foreground location so it can show where you are.
Tap Import and pick a georeferenced PDF map or a GPX trail from your device.
Navigate offline and hit Record to capture your trail. That's it.
Inukshuk is free and open source under the MIT license — no company, no paywall, no premium tier. It gets better when people who actually hit the trails help shape it.
