About Mariner GPS

Mariner GPS is a lightweight, offline-first tool designed for seafarers providing:

• Live GPS with precise coordinates display.

• Course & Bearing
See your Course Over Ground (COG) and smoothed bearing in degrees, filtered to eliminate jitter.

• Smoothed Speed
Raw GPS speed can jump wildly; our exponential smoothing algorithm delivers a rock-steady readout.

• Sunrise & Sunset Times
Instant access to today’s sunrise and sunset at your location—no extra downloads or data usage.

• Auto-logging of GPS position and timestamps (local + GMT)

• Map view showing your vessel’s heading

• Offline
No internet connection required. Works even in airplane mode.

Simple. Reliable. Nautical.
