About this app

A simple and easy to use Compass to retrieve useful information about your current position such as true Geographic north and true altitude above sea level.

• Works perfectly offline and without network access
• Geographic north using magnetic declination
• True altitude above mean sea level (AMSL)
• Sunrise & Sunset times
• Azimut angles in deg, grad, mrad, gon
• Various dials and color themes (including high contrast)
• Angle measurement (with dials including measuring capabilities)
• Bubble Level functionnality (available in iPhone dial)
• Use EGM96 as the geoid reference for computing altitude
• Latitude & Longitude in MGRS, UTM coordinate formats
• Latitude & Longitude in DD, DMM or DMS format
• British National Grid (OSGB86) coordinate system
• SwissGrid (CH1903 / LV95 / MN95)
• Magnetic field strength to detect potential perturbations
• Sensor accuracy
• Address of your current location (requires data connectivity)

Compass better works outside where magnetic perturbations are low. Magnetic closure cell phone cases may also disrupt the accuracy of the compass.

EGM96 (Earth Gravitational Model) is used as the geoid reference to compute true altitude above sea level from data collected by the GPS sensor. UTM (Universal Transverse Mercator) is a system for assigning coordinates to locations on the surface of the Earth.

Have fun !

Ratings and reviews

I downloaded this app. while touring the southwest. It was great to know the elevations of all the mountains & valleys. with compass was a plus. Both features appeared to be accurate. Along with the sunrise & sunset times. Great features all combined in one app.. Great for auto or hiking. Look forward to using it again. Thanks

I enjoy the widget that displays the sunrise and sunset times as well as the elevation. Clean on the eye (doesn't clutter up my home screen) yet displays the aforementioned info that I find interesting and useful at a glance that seems quite ACCURATE (depending on whether I am sitting or standing at my desk the elevation will read between 5,170 ft and 5,172 ft) and it reshes the metrics at a customizable interval rate. Even at a high refresh rate it doesn't seem to affect my battery life at all.

Just downloaded this app, but I like the interface and features. I use astronomy and photography apps and they have a calibration feature that is the same figure 8 motion, but I discovered last night that I wasn't able to just easily force recalibration, and the orientation of their data was glaringly off by several degrees. I am unable to turn on full-time access to the device's location data for those apps. But this app allowed me to turn on full-time access, so even that's an improvement.
