Sea Maps & AR: Boat GPS app analytics for October 8

Sea Maps & AR turns your iPhone into a complete marine navigation toolkit: nautical charts, smart routes, augmented reality and live marine weather in one app. Free to download, no account needed. Built for skippers, sailors, anglers, kayakers and weekend boaters who want serious tools without depending on cell coverage. WHAT IT DOES • Nautical charts with harbors, marinas, lighthouses, buoys, anchorages and thousands of marine POIs from OpenStreetMap, always up to date. • Smart routing that automatically avoids the coastline, with live distance, ETA and bearing. • Augmented reality: point the camera at the sea and the next waypoint appears as a glowing 3D beacon, with distance and bearing overlaid in real time. • Anchor alarm: set your swing radius and get woken up if the anchor drags. Works in the background with a loud alert. • One-tap MOB (man overboard): instantly saves position, bearing and distance from the drop point. • Logbook: every trip is recorded automatically: GPS track, distance, average and top speed, notes. • Weather routing: plan your passage using live wind and weather along the route. • Marine weather by Open-Meteo: wind, gusts, waves, pressure, tides and sea state. • Offline charts: download your cruising area before you cast off (cache configurable up to 10 GB) and keep navigating with zero signal. • GPX import & export: bring routes from your plotter or share tracks with the crew. • Apple Watch companion: bearing, distance to waypoint, anchor watch and MOB right on your wrist. WHO IT'S FOR Sailors, powerboaters, RIB owners, kayakers, anglers and charter crews, in the Mediterranean, the Atlantic, the Baltic, the Caribbean or on your home lake. OFFLINE FIRST Download your areas before leaving port. Charts, routes, anchor alarm and MOB keep working without signal. PRIVACY No account, no hidden tracking. Your position stays on your iPhone. Charts use OpenStreetMap data, weather uses Open-Meteo (no API key, no signup). The app contains Google AdMob (removable with Pro) and shows the iOS ATT prompt: you decide whether to allow or deny ad tracking.
