Installing
- 1. Tap the button above and open the downloaded file.
- 2. Android will warn about installing from an unknown source. Choose Settings and allow it for your browser — this is normal for apps not distributed through the Play Store.
- 3. Tap Install, then open Kraverse and create your account.
- 4. Updating? Install the new file over the old app. Your account and downloaded sheets are kept.
Works with no signal
GPS is satellite, not cellular. Your position, the grid readout, markers and track recording all run on the device.
Your own survey sheets
Upload sheets as PDFs. Contours, spot heights and the printed grid stay exactly as published — not a simplified basemap.
Grid reference at a glance
Your MGRS reference, bearing and fix accuracy stay on screen. Long-press to copy.
Turn-by-turn guidance
Spoken directions with off-route warnings. Plan on roads while online, or direct to any point with nothing at all.
Free to use
Create an account in the app to upload your sheets and use them offline.
