Description
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.

It is a good app to use for basic knowledge of directions and altitude

Make it easier to use it is so d difficult, so please make it easier
★★★★★Luke “Eternal Dark X” Goodwin· Jul 15, 2026
Great app, I love how it has milliradians and radians as well! 👍
★★★★★David Kelly-Durrant· Jun 28, 2026
Does exactly what it says on the tin 👌 Elegant simplicity and very accurate with a very readable display 👍

Just want to collect your data and share with hundreds of external companies. It isn't possible to untick sharing and still use the application.
★★☆☆☆J D· May 20, 2026
The app's page on the play store says that they do not share data with 3rd parties, but once you launch the app their terms say that they do. If they are going to give inaccurate or misleading information, I am not comfortable having the app on my phone. The app also requires you to either pay or allow *targeted* ads - I am used to either ads or payment, but requiring targeted ads is new to me and a step too far for a basic app. The compass itself does seem accurate and responsive, at least.

Adware beware. If you opt out of the intense, advertising tracking and retargeting cookies you cannot use the app unless you pay or change your consent to opt-in. This sketchy methodology is called "consent-or-pay” or “pay-or-okay” and it isn't legally compliant with most domestic and international privacy laws. Consent can't be freely given if it is forced. I'm surprised a lawsuit hasn't been filed yet.
