Works with no signal
GPS comes from satellites, not the mobile network. Your position, grid readout, markers and track recording all keep working offline.
Offline land navigation
Your map sheets.
Your position.
No signal needed.
Kraverse puts your own topographic map sheets on your phone and shows exactly where you are on them, with your grid reference, bearing, markers, tracks and route guidance. Everything runs on the device, far beyond mobile coverage.

Features
Everything you need between the grid lines
Built for people who navigate from real map sheets: survey teams, guides, rangers, field crews and expeditions.
Your own sheets
Upload map sheets as PDF files. GeoPDFs place themselves automatically. Other sheets are set up by tapping known points or typing the corner coordinates.
Grid reference at a glance
Your MGRS grid reference, bearing, altitude and fix accuracy stay on screen. Go to any grid reference in a couple of taps.
Markers and tracks
Drop colour-coded markers, record your track as you move, and keep everything on the phone.
Route guidance
Follow a route with spoken directions and off-route warnings. Plan on roads while online, or go direct to any point with no connection at all.
Private by design
Your sheets belong to your account and are visible only to you. Your position, markers and tracks never leave your phone.

Questions
Frequently asked
Does it really work without internet?
Yes. You need a connection to sign in, upload a sheet and download it to your phone. After that, the sheet, your GPS position, grid reference, markers, tracks and direct routes all work with no signal.
What map sheets can I use?
Any map sheet you have as a PDF, up to 500 MB. GeoPDFs, which carry their own coordinates, are placed automatically. For a plain PDF you can type the corner coordinates printed on the sheet, or tap a few points whose position you know.
Can other people see my sheets?
No. Sheets belong to the account that uploaded them and are visible only to you. Your location is never sent to our servers. See the Privacy Policy.
Which phones are supported?
Android phones today, installed from our download page. The iPhone and iPad version is coming soon.
