About
LD-Log (also marketed as Geo-Log and Sail-Log) is a powerful GPS track-logging application for Android that covers a wide spectrum of travel and outdoor activities. At its core, the app records travel routes using the device's built-in GPS receiver, with waypoints captured either manually or automatically at user-defined minute intervals — keeping battery consumption to a minimum during multi-day journeys. A switchable high-frequency tracking mode enables second-by-second recording when precision matters. Each route includes an editable waypoint list that functions as a detailed travel diary or nautical ship's log. Users can attach text notes and multiple photos to individual waypoints, either captured in-app or imported later. A dedicated Sail Mode records separate distances for sail and engine usage and supports standardized nautical log entries. The integrated map view draws on a broad selection of online tile sources — OpenStreetMaps, OpenSeaMaps, OpenTopoMaps, USGS, NOAA Nautical Charts, and more — while caching tiles for offline use. Custom offline maps and KML-based destination imports are also supported. Navigation aids include a bearing compass with distance-to-destination readout. Data portability is a highlight: trips can be exported as GPX, KML, or KMZ files with embedded images, or as CSV, plain text, and printable HTML travel reports. All data is stored locally for maximum privacy. LD-Log is ad-free and requires only essential Android permissions. It is ideal for hikers, sailors, cyclists, road-trippers, photo geotag collectors, and professionals engaged in field cartography or route documentation.
Key Features
- Battery-Efficient GPS Logging: Records routes at user-defined minute intervals to minimise battery drain on long journeys, with an optional second-by-second tracking mode for precision.
- Travel Diary & Nautical Logbook: Attach text notes and multiple photos to each waypoint; a dedicated Sail Mode captures standardised nautical log entries including separate sail/engine distances.
- Offline Map Support: Access OpenStreetMaps, OpenSeaMaps, OpenTopoMaps, NOAA charts, and more; cached tiles and custom offline maps keep navigation working without a data connection.
- Flexible Export Options: Export trips as GPX, KML, or KMZ files with embedded images, or generate CSV, text, and printable HTML/PDF travel reports to share or archive.
- Navigation Tools: Integrated bearing compass, direct map-based destination marking, KML destination import, and distance-to-destination display aid route planning on land and at sea.
Use Cases
- Hikers and trekkers tracking multi-day routes with battery-efficient GPS logging and geotagged photo journals.
- Sailors maintaining a complete digital ship's log with standardised nautical entries, sail/engine distance separation, and offline chart support.
- Road-trippers and cyclists documenting long journeys with waypoint diaries, exported as printable HTML reports or GPX files.
- Travel bloggers and content creators capturing geotagged photos and detailed route histories to accompany published content.
- Field professionals in forestry, cartography, or surveying collecting and exporting geo-locations and points of interest without relying on mobile data.
Pros
- Ad-Free & Privacy-Focused: No advertisements and all data stored locally on the device, with only essential Android permissions required.
- Truly Offline Capable: Cached map tiles, custom offline map support, and local-only data storage mean the app works reliably without any internet connection.
- Versatile Across Activities: Purpose-built modes and tools cover hiking, cycling, road trips, sailing, and professional field work like cartography and geo-location collection.
- Rich Data Export: Multiple export formats (GPX, KML, KMZ, CSV, HTML) with embedded photos make it easy to archive, share, or continue work in other apps.
Cons
- Android Only: The app is exclusively available for Android; there is no iOS, web, or desktop version.
- Key Features Behind Paywall: The free version limits routes to a maximum of 2 per trip and restricts features like second-tracking, multiple images per waypoint, and destination imports.
- No Altitude Recording: LD-Log intentionally omits altitude data due to GPS inaccuracy; users must use external tools such as Google Earth for elevation profiles.
Frequently Asked Questions
Is LD-Log free to use?
LD-Log offers a free version with core GPS logging features and a demo of premium functions. The full paid version unlocks unlimited routes per trip, second-by-second tracking, multiple photos per waypoint, destination import, and more.
Does LD-Log work without an internet connection?
Yes. The app runs fully offline. Previously viewed map tiles are cached on the device, and custom offline maps can be loaded. No data connection is needed for GPS tracking or diary entry.
What activities is LD-Log designed for?
LD-Log supports hiking, bicycle tours, offshore sailing, city walks, road trips, boat tours, photo geotagging, POI collection, and professional cartography — for both recreational and professional users.
What file formats can I export my routes in?
Routes can be exported as GPX, KML, or KMZ files (with embedded images). Travel reports can be generated as CSV tables, plain text, or HTML files suitable for printing or PDF conversion.
Does LD-Log record altitude?
No. Altitude data from GPS receivers is considered too inaccurate for reliable logging, so LD-Log deliberately omits it. You can add a precise elevation profile post-trip by importing your GPX file into a tool like Google Earth.
