## Description

SeaCheck is something I built for my own small-boat sailing — a deck-side companion to paper charts, not a replacement for them.<br><br>I use it for boat speed, coordinates, a quick chart position without going below, passage sketches, and anchor alarms. I&#39;m sharing it in case another coastal sailor finds it useful. No launch, no support promise — use at your own risk.<br><br>NOT FOR PRIMARY NAVIGATION<br>Aid to navigation only. Not a certified chart plotter. Maps use OpenSeaMap / OpenStreetMap volunteer data and may be outdated. Always carry official, corrected nautical charts.<br><br>FEATURES<br>• GPS on chart — COG, SOG, bearing<br>• Passage planning, waypoints, GPX export<br>• Offline region packs (Wi‑Fi download)<br>• Anchor, arrival, and off-course alarms<br>• Track recording<br>• EN / DE UI<br><br>Free. No ads. No analytics. Data stays on your device.
