Has a problem with permissions. Even when set manually the app doesn't give your variation at your location automatically, instead you have to select a nearby location.

Good application. To those complaining about automatic location detection, allow the "location permission" to this application.

Ok

The gps is not functional. Secondly, the app when launched should retrieve the local gps coordinates not those of Spain. It's practically almost useless without the gps.

Works great...! For those having trouble the app doesn't automatically prompt to allow GPS, go to ( Setting --> Apps --> Permissions ) and allow location, this worked for me.

It's a good app but the GPS locator does not work. Can get by without it but it's there so it should be working

About this app

VARIATION for the current day.
Used in navigation with a magnetic compass.
-
Variation is the angle between the magnetic and geographic meridians at any place, expressed in degrees east or west to indicate the direction of magnetic north from true north. Called MAGNETIC VARIATION when a distinction is needed to prevent possible ambiguity. Also called MAGNETIC DECLINATION. (Bowditch)

The app uses the World Magnetic Model: WMM2020.
The new model is valid from 10/12/ 2019 through 31/12/2024.
See: https://www.ngdc.noaa.gov/geomag/WMM/DoDWMM.shtml

Your last position is automatically saved.
- Storage permission needed for Google Maps cache and for save your position.

COURSE CALCULATOR
Compass and true course.
DEVIATION COEFFICIENTS
