Let BlueStacks turn your PC, Mac, or laptop into the perfect home for Nautical Calculator, a fun Tools app from Gabriele Giacomo.

About the App

Nautical Calculator is a practical, no-frills companion for anyone who plots courses, studies navigation, or just loves maritime math. Built by Gabriele Giacomo, this Tools app focuses on doing the essentials right: fast calculations, clear outputs, and handy visual aids. Prefer a bigger screen while planning? It also runs smoothly on BlueStacks.

App Features

• Great-circle & rhumb-line solver: Enter two positions to get courses, distances, meridional parts, and the great-circle vertex, plus quick visual plots to see it all at a glance.
• Advance a position (DR): Start from a known fix and project where you’ll end up after running specific courses and distances. Average speed and ETA checks are right there when you need them.
• Route planning, your way: Build waypoint routes manually, stay on the same rhumb line, mix routes with parallel limits, correct legs, find parallel/meridian intersections, and even plan an opposite‑course rendezvous.
• Wheel-over calculations: Compute the wheel-over point and turning details to cleanly roll into the next leg.
• Compass checks: Assess compass error/deviation and related compass detections to keep headings honest.
• Tides, currents, and drift: Work through tidal height/current problems and solve set-and-drift with straightforward steps.
• Sun, stars, and almanac: Use ABC tables, azimuths, right ascension tools, and a built-in nautical almanac. Handle celestial sights, meridian transits, position lines, and amplitude at sunrise/sunset.
• Coastal navigation helpers: Practical tools that support bearings, fixes, and course adjustments near shore.
• Wind with Beaufort: Estimate wind strength and categorize conditions using the Beaufort scale.
• Draft survey: Run draft survey calculations quickly during loading or unloading.
• Converters & utilities: Handy unit converters and other small tools that save time on deck or at the desk.
• World map view (not a chart): See your routes on a simple world map for context. It downloads once for offline use and appears at wider scales (about 60–70 NM and beyond). It’s not a nautical chart and isn’t for real-world navigation.
• Free to use: All the core features are available without cost, making it easy to keep Nautical Calculator in your kit.
