Store description excerpt
**Neptune's Route** Neptune's Route is a professional navigation application for planning ocean passages and long-distance voyages. The app calculates Great Circle routes using both classical spherical navigation and highly accurate WGS84 geodesic calculations based on Charles Karney's algorithms (GeographicLib). Both calculation methods can be compared directly. For practical voyage planning, Neptune's Route supports Composite Sailing with a user-defined Maximum Latitude, allowing Great Circle routes to be limited in high latitudes while maintaining efficient ocean passages. Features * Great Circle calculations (Spherical Earth) * Great Circle calculations (WGS84 / Karney) * Composite Sailing with user-defined Maximum Latitude * Great Circle Position (daily run / Etmal) * Meridian Intersection Position * Great Circle Vertex calculation * Initial and Final Course * Rhumb Line course and distance between all generated waypoints * Interactive map * GPX export for navigation software * S-421 route export for modern ECDIS systems * RTZ route export for modern ECDIS systems * PDF voyage reports * Save and reload calculated routes * Works completely offline * No subscriptions * No advertisements Neptune's Route is designed for professional mariners, yacht skippers, sailing enthusiasts, and maritime students who require reliable and accurate Great Circle voyage planning. All calculations are performed directly on your device. No internet connection is required for route calculations, and no navigation data is transmitted to external servers. Neptune's Route combines classical navigation methods with modern geodesic algorithms to provide accurate, practical, and easy-to-use ocean route planning.
