The graphic has true and magnetic norths switched. The numeric result is colored, but what does that mean? Should have E or W to indicate direction of magnetic north from true north.
Under the detail view the magnetic declination is correct numerically BUT the compass graphic shows the offset in the wrong direction. In my area Magnetic North is west of True North. The app shows the correct value, but the compass graphic shows MN offset to the east of TN. Good thing the app has the warning not to use for navigation!
This app works well. I checked it against the government web site for world magnetic model. It works flawlessly on my iPhone and iPod Touch. It's a great app for estimating magnetic variation.
The software appears to have sign error for the magnetic declination...? The software does not reproduce the samples shown on the App page! Who is checking this application?
Won't work
