Description
Marine Instruments turns your iPhone into a boat instrument display. Connect it to your boat's NMEA 0183 WiFi gateway and see your real instruments — wind, depth, speed and heading — on a big, glare-friendly screen. No gateway? The built-in sensors still give you heel angle, a barometer with storm alarm and a GPS trip log.
BOAT INSTRUMENTS OVER WIFI (NEW)
Connects to any NMEA 0183 WiFi gateway: Orca Core, Yacht Devices, Digital Yacht, Vesper and many more
Speed over ground (SOG), depth, apparent wind angle & speed, heading
TCP or UDP, configurable host and port (standard 10110)
Automatic reconnection when the connection drops
Values mark themselves stale ("--") within seconds if data stops — no misleading frozen numbers
HEEL & ATTITUDE INDICATOR
Real-time pitch, roll and yaw with an aircraft-style horizon
Maximum heel angle tracking for port and starboard
One-tap recalibration to your mounting position
Motion history graph
BAROMETER
Live atmospheric pressure from the iPhone's own barometer sensor
4-hour pressure graph with trend arrow
Automatic alarm with vibration when pressure changes faster than 1.5 hPa/hour — a classic early storm warning
If your phone has no barometer, pressure from the gateway (MDA) is used instead
TRIP LOG
Distance in nautical miles, current/average/max speed in knots
Trip duration, reset whenever you like
Recording happens while the app is open — the screen stays on automatically, so mount the phone and sail
SEA STATE
Beaufort scale estimate (0-12) from vessel motion
Wave height estimation
REAL NIGHT MODE
Every instrument — attitude, barometer, graphs, trip log and NMEA tiles — switches to a red-on-black palette that preserves your night vision
Remembered across launches
PRIVACY
All data stays on your device. No accounts, no analytics, no tracking. The only network connection the app ever makes is to the gateway IP you enter yourself.
Note: for accurate heel and wave readings, mount the device in a fixed position on your vessel.
