Track Ledger - Log GPS Data

Offline-first GPS logger for field work. Record raw tracks, review them on a map, and export CSV — GPX & GeoJSON with Premium.

Track Ledger is an offline-first GPS / GNSS track logger for engineers, surveyors, and field work — not a fitness or social app.

Record raw location points with time- or distance-based sampling. Watch live distance, speed, and GPS accuracy while you record. When you finish, review elevation profiles, overlay completed tracks on OpenStreetMap tiles, and export your data.

FEATURES • Raw GNSS logging with no path smoothing • Time- or distance-based sampling • Pause and resume • Live stats: distance, speed, accuracy • Track summary with elevation chart • Map overlay for completed tracks • CSV export on all tiers; GPX and GeoJSON with Premium • System share sheet • Projects to organize recordings • Optional background recording (Premium) • Light, dark, or system appearance • 12 display languages • No account required — tracks stay on your device unless you export or share

LOCATION Location is used only for track recording while a recording is active (and optionally in the background if you enable Premium background recording), not as an app feature for ads.

PRIVACY & ADS Optional ads may appear unless you unlock Premium. See the in-app Privacy Policy for details about analytics, crash reporting, and advertising SDKs.

Premium is a one-time purchase (not a subscription) to remove ads and unlock advanced exports and background recording. Restore purchases anytime in Settings.
