Starlink Maritime requires Ocean Mode beyond 12 nautical miles offshore. Forget to switch it on and your connection goes dark exactly when you need it. Starlink Ocean Mode tracks your distance to the territorial-waters line in real time and alerts you the moment you cross. WHAT IT DOES • Live distance to the 12 NM territorial waters line • ETA to crossing based on your current heading and speed • Push alerts when you're approaching, when you cross outside, and when you re-enter • Speed, heading, distance-to-nearest-coast, and exact position • Background GPS monitoring — works with the screen off and the app closed HOW IT WORKS Your device's GPS feeds a local boundary calculator that uses a high-resolution coastline dataset to figure out how far you are from the nearest shore. Subtract 12 NM and you have your distance to the territorial waters line. Everything runs on-device — your position is never transmitted to a server. A small foreground notification stays active while monitoring is on, so the OS keeps the GPS service alive. When you're within minutes of crossing, you get a push alert reminding you to switch Starlink to Ocean Mode. Same on the way back in. WHO IT'S FOR Cruisers, sportfishermen, deliveries, and any boat that uses Starlink Maritime and crosses the 12 NM line. Built by sailors who got tired of forgetting. PRICING One-time purchase. No subscription, no recurring charges. Includes a 7-day free trial — full functionality on first launch, paywall after the trial. IMPORTANT This app uses simplified coastline data and approximate distance calculations. Treat it as a convenience reminder, not a legal compliance tool. Always consult official charts and your vessel's navigation systems for territorial waters compliance.
