RDBK

Create, navigate and record rally-style roadbooks — free and offline-first, with background GPS. Editor, Reader, Tripmaster, Recorder and Ranking in one app.

RDBK is a complete, free toolbox for digital roadbooks — create them, navigate them, record them and score them. Built for any self-guided adventure: 4x4, motorbike, bicycle, trail running or hiking.

ROADBOOK READER Navigate like a rally co-driver: a paper-style roadbook table with tulip vignettes, distances, CAP headings and danger markers. Notes advance automatically by GPS as you reach each waypoint (or manually if you prefer), with color-coded progress and an optional mini-map per note. Trip mode for adventures, Competition mode with waypoint validation, penalties and a signed result QR.

ROADBOOK EDITOR Create professional roadbooks from a GPX file, by recording a route live, or by drawing directly on the map. Edit the track right on the map (draw, cut, join, reverse, simplify), and give every note a tulip vignette, road types, FIA-style danger grades, CAP headings, speed limits and waypoint types. Export as .rdbk or GPX, or save to your free account and share it publicly.

TRACK RECORDER Record routes in the field with accuracy-aware GPS sampling, pause/resume, instant waypoints, geotagged photos and crash-safe logging that survives an app kill. Background recording keeps working with the screen locked.

TRIPMASTER A rally-style trip computer: total and partial odometers with quick ±10 m corrections, speed with configurable alert bands, heading, stopwatch and waypoint counter.

RANKING Scan competitors' result QR codes, verify their signatures and build instant rankings — accuracy, CAP, speed and regularity — with CSV export.

WORKS OFFLINE, OPEN BY DESIGN Everything works without an account and without coverage — an account only adds free cloud storage and public sharing. Roadbooks use the open .rdbk format (documented at rdbk.app/standard): one self-contained file with the track, notes, vignettes and icons. Browse community roadbooks at rdbk.app.

Free, no ads. Available in English, Spanish, Italian, German and French.
