Only for iPhone

iPhone
Now with NMEA over WiFi: see your boat's wind, depth, speed and heading live. Plus heel angle, barometer with storm alarm, trip log and true red night mode.
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.

Marine Instruments 2.0 — your boat's real instruments, on your phone.
• NEW: NMEA 0183 over WiFi. Connect to your gateway (Orca Core, Yacht Devices, Digital Yacht, Vesper…) and see SOG, depth, apparent wind and heading live. TCP or UDP, auto-reconnect, stale-data indication.
• NEW: Real night mode. Every screen — attitude indicator, barometer, graphs, trip log and the new instrument tiles — now dims to red-on-black, and the setting is remembered.
• Barometer fallback: phones without a barometer can use gateway pressure (MDA sentences) for the trend and storm alarm.
• Honesty fixes: removed non-functional background-recording scaffolding. Recording happens while the app is open (the screen stays on automatically).
