About Mariner GPS
Offline GPS utility with speed, bearing, COG, sunrise/sunset & logging with map.
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.
