GeoSea

The GeoSea app, which marks the limits, is the ultimate safety tool for recreational boaters. Enjoy the sea with the peace of mind of knowing you're always within the area permitted by your nautical license.

Whether you have a Navigation License (Titulín), a Basic Navigation Certificate (PNB), or a Recreational Skipper's Certificate (PER), going out to sea sometimes raises the question: "Have I gone too far from the port?" GeoSea solves this automatically and easily.

HOW DOES IT WORK?
Simply open the app, select your limit (2, 5, or 12 miles), and save your phone. GeoSea uses your device's GPS to calculate your exact distance to the nearest port or shelter in real time. If you approach your legal limit, the app will emit an audible and vibration alarm to warn you, even with the screen off!

KEY FEATURES:

Precise boundary alarm: Set your navigation radius (2 miles, 5 miles, etc.) and receive instant alerts if you're about to cross it.

Background GPS: Designed to not interrupt your day. The app continues to efficiently calculate distances even when your phone is locked in your pocket.

Extensive database: Connected to a vast network of harbors and shelters to ensure that distance calculations (Haversine formula) are always accurate based on your current location.

Clear and distraction-free interface: Designed for use in sunlight and on the move. A quick glance is all it takes to know your safety status.

Don't let worrying about distances ruin your day of fishing, cruising, or sailing. Download GeoSea, set your boundaries, and focus on enjoying the sea with complete peace of mind.
