NAVLITE is a clear, fast and beautiful coastal navigation app for boaters, sailors and kayakers. Built for the sea, it puts your position, heading and speed on a crisp marine chart so you always know where you are and where you are going. NAVIGATION Follow your live GPS position with course over ground (COG) and speed over ground (SOG). A heading vector shows where you are headed. Keep north up or rotate the chart to your heading. MARINE CHART A high definition vector chart powered by MapLibre and OpenStreetMap data, with the OpenSeaMap layer showing buoys, lights, beacons and harbours. Switch to Sentinel 2 satellite imagery to read the coastline and anchorages at a glance. Day and night modes protect your night vision. PLAN AND RECORD Create routes with waypoints and follow them leg by leg. Record your tracks, drop points of interest, and measure distance and bearing between any two points. SAFETY A man overboard mode marks a position with one tap and guides you back with bearing, distance and elapsed time. An anchor watch alarm warns you if your boat drifts beyond your chosen radius, even when your phone is locked. OFFLINE Download your sailing area, base chart and sea marks, and navigate with no network at all. Your data stays on your device. FREE AND PREMIUM NAVLITE is free, supported by occasional ads on some tools. Go premium to remove all ads. The chart, position sharing and man overboard mode are never interrupted.
