Professional Bearing Compass with real-time camera and map views, bearing markers and 8x zoom.

" nicely, we tried it out at the Voiles d'Antibes...the Captain's response when trying it out was 'Cool!'." - Boatbookings, The World's Leading Online Yacht Charter Broker

Compass Eye can be used to help with navigation on land, sea or air as a bearing or marching compass.

Compass Eye is fully gimballed and works accurately in all orientations and angles, unlike most compass apps which only show the correct heading when held level and close to horizontal.

“This app is a compass on steroids! It is fully gimballed so it will work in any orientation on your iPhone or iPad.  You can use it on land while hiking or as a hand bearing compass on the ocean or in the air while flying.” i-Marine Apps

"The app's compass works way better than the iOS default compass and I don't have to wave my iPhone in the air every time I launch the app." Gizmodo Review (App of The Day, 6th December).

- Real time, accurate in all orientations
- Compass overlaid on live camera view
- 8x Digital zoom
- Back, transit, or collision bearing marker
- Draggable Green and red bearing lines
- Triangulation bearings
- Optional time, date and GPS location information.
- Magnetic or True North setting with variation based on location
- Live map view with position and track.
- Artificial Horizon.
- Night Vision mode.
- Low light boost on iPhone 5.
- Location sharing.

Enabling GPS also shows the Speed Over Ground (SOG) , Course Over Ground (COG) and optional COG bearing (purple).


Taking a bearing - look through your iPhone at the distant object, line it up with the centre line and read off the bearing! Zoom in to get more accuracy.

Setting a bearing - look through your iPhone at the point you want to get to, tap the Bearing button (Top right) and follow the yellow bearing line.

Setting a bearing from the map - lay the iPhone flat, rotate or drag a bearing line to line up with the point you are aiming for and follow that bearing.

Triangulation - use the three bearing lines - yellow green and red to take bearings on 3 points. Capture the view including compass, bearings, time and location information (Camera button on left of screen) and then use the photo to plot a fix on a chart.

Clearance bearings to a point on an approach - set one line to the minimum bearing (e.g. the angle the target must bear greater than) and the other line to the maximum bearing and navigate between the two. Use the colours according to the IALA lateral markings to help you remember which way to steer. e.g. in North America use red for the minimum bearing and green for the maximum (vice-versa in Europe!).

Based on an iPhone 5 camera the image specification at full zoom compares favourably with a 7x50 pair of binoculars:
- Field of Vision at 1000m at 8x: 122m
- Angle of view at 8x: approx 7 degrees
- ISO 3200 or better.

Compass Eye should only be used for basic navigation assistance. Never rely solely on the digital compass for determining direction, proximity or distance. The user is responsible for the prudent use of information provided by this application and must not use it for direct navigation.

Requirements: iOS device with back facing Camera, Magnetometer and accelerometer (gps is optional).

N.B. Battery consumption can go up considerably when the iPhone's GPS is enabled, Compass Eye allows you to turn off location display to preserve battery life.
