This very useful app has been fully upgraded to the latest World Magnetic Model from the NOAA using SwiftUI tools and functionality. It has new sharing capabilities added using both email and SMS capabilities.

The WMM model has been upgraded to the NOAA 2020 standards for accurate calculations and the "My Location" feature is now included in the app without the need for an in-app purchase.

The "My Location" in-app purchase feature has just been significantly upgraded to allow you to pan and zoom to other locations on the map, anywhere on the planet. When you drag the map from your current location a notice will ask you to enter a new elevation for your new coordinates on the map. The magnetic declination will automatically be calculated for you using the panned map latitude and longitude coordinates at the yellow centre target on the map, as well as your entered elevation value. This is a very powerful, very convenient and easy feature to use. It will save you a lot of time.

Location services have been improved for the "MyLocation" feature. This upgrade will ensure accurate automatic calculations of magnetic declination for your current position.

Corrected the Restore Purchases code for the Restore button.

A new "MyLocation" button has been added to initiate access to a map page. This is available as a one time, low cost In-App purchase. Once purchased this button takes you to a map feature which will accurately locate you on the map and will automatically determine your latitude, longitude and elevation. Then a calculation is done to provide an accurate magnetic declination for your exact location. This is a very useful user feature to replace the need for manual entry of this information for your location. The manual entry is still available and is free, as before, for all other locations of interest. A "Restore Purchases" button is available to permit moving this app to your other devices without having to repurchase the access token.

No changes, the app version was revised to permit the addition of an app preview video on the app store. Same functions as before.

Same features but I have added the iRate feature to make it quick and easy for users to rate this app if they chose to. Hopefully it will encourage the users to provide feedback to me on this free app. Improvements, recommended changes?
