Maps and tools for outdoor navigation

➤ Sail-Log tracks your travel routes using the device's GPS receiver. Waypoints are taken either manually or automatically with a user-definable interval set in minutes. As such, the app is designed to consume very little battery power. Sail-Log also offers a tracking mode, allowing you to record your movements by the second.

➤ An editable waypoint-list for each route of your trip lets you keep a complete nautical ship's log in an intuitive manner. Sail-Log will allow you to enter text, choose from a set of logbook entries or shoot photos in-app as well as import them at a later time. Many different options are available for convenient storage of trips, routes and logs.

➤ The map view features a selection of different online map sources. Previously viewed map tiles will remain available while offline. You may also include custom offline maps. Create destination points and navigate with the help of the integrated bearing compass and the numerous map tools, whether in the open country or at sea.

➤ Sail-Log is can be used to document a wide range of travel situations including: offshore sailing cruises, voyages, ship and boat tours, photo geotagging, collecting geo locations (POI), cartography, etc. - for professional or recreational use.

This is a new version of the popular app LD-Log and is identical to it, but without the option to deactivate sail mode.

If you would like to try it first, search for the free version LD-Log Lite.
