A marine compass that tells you the truth.
Course-steer, true north, and speed in knots — butter-smooth and fully offline.
Point, tap the anchor, and your course is locked. A glowing arc on the ring shows your off-course delta, shrinking to zero as you steer back. Nudge ±1° or ±10° — no typing, even helm-mounted.
Heading corrected for magnetic declination by the on-device World Magnetic Model and your actual position. An honest T/M badge always says which north you're reading.
Heading, coordinates and SOG in one cluster. A still-gate pins speed to an honest 0.0 the moment you stop — no three-second GPS fade.
The glossy rose glides with adaptive filtering and frame-rate interpolation while every letter and numeral stays upright. Readable from helm, dash, or hand.
Heading from on-device sensors, position from on-device GPS. No account, no ads, no tracking, no internet required. Ever.
Landscape mode with large, high-contrast readouts, course controls clear of the dial, and the screen stays awake while you navigate.
Aim at your desired heading — the bow, the road, the buoy.
The course locks. A cyan arc appears on the ring, marking your delta.
Follow the arc back to zero. Trim ±1° / ±10° like cruise control.
Your position never leaves your device.
No accounts, no analytics, no tracking, no cookies — heading from your
sensors, position from your GPS, nothing else.
