About this app

A simple and easy to use Compass to retrieve useful information about your current position.

Free and without Ads
• Magnetic & geographic north using magnetic declination
• Sunrise & Sunset time
• Various skins and color themes (including high contrast)
True altitude above sea level at your current position
• Use EGM96 as the geoid reference for computing altitude
• Latitude & Longitude in MGRS format
• Latitude & Longitude in UTM format
• Latitude & Longitude in DD, DMM or DMS format
• Magnetic field strength
• Sensor accuracy
• Address of your current location

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 !

Easy to use, full featured compass with other helpful features. I just downloaded it because things like this interest me. I'm not really going out and putting it to the test. I am grateful to the developers for making it, and allowing it's use without ads cluttering it up. I would gladly give my support by purchasing the upgrades, but I am a disabled First Responder, and do not have any income, so my words are all the support I can give. Thanks guys, keep up the good work, and good luck! 👍

Works quite well. Only downside is that the elevation feature doesn't seem to update very frequently, and after a few moments, doesn't seem to update at all until the app is closed and reopened. The compass needs a quick calibration each time the app is opened, but a couple figure-8s with the device fixes that every time. All in all, a solid app when the need for a compass is present.

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.
