Built as a personal log first — every feature exists because I needed it at sea.
Type into either format and the other updates live. DMS → decimal, decimal → DMS — one tap to switch direction.
Latitude stops at 90°, longitude at 180°, minutes at 60. The fields snap back — you physically cannot enter an invalid coordinate.
Tap "Use my current location" and the app fills both fields from GPS — in whichever format you're using. Read once, on-device.
Copy latitude or longitude individually from the preview row, or copy both together as a clean formatted block.
Light and dark themes that follow your system setting. Status and navigation bars adapt automatically.
No ads, no analytics, no accounts, no tracking. No internet permission — the app literally cannot phone home.
Learn how to convert between DMS and decimal, clamp inputs, use your current location, and copy results — step by step, in two minutes.
