About this app

Developer Description

A Compass, with geographic north, true altitude, address, sunset & sunrise times

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 !

it WORKS with Samsung A-16 5G. . . . which is good. Don't forget to go use "setting"

★★★★

Larraine Lage

very good compass but it wants to run in the backgrou d is kind of creepy and it seems to take up a lot of RAM so it slows everything down. You can turn this off so there's that

I've used this before on another smartphone. Now I found it again. It's as handy as can be. Just press the button and learn a lot on one screen. It's very important when in a strange town. My whole weltanschuang is based on compass directions because I was raised on a farm in western Minnesota. I also like knowing the elevation in hill country. However I value my privacy and don't want to be owned by anyone on the internet, so I'll have to quit this app.
