Love this app. When using route correction with the Great Circle format, the heading is still in rhumb line. My mistake or am I missing something. Thank you.

The map could use a little improvement, I understand that it's not for navigation, but I would like to view it in larger scale. Otger than that, this is a brilliant app!

Only tested the app with celestial calculations using the sun. UTC time should be calculated vice versa, since it is Greenwich the reference not the local time zone. Therefore actual UTC -3 must be inputted as +3 in the app to get a reasonable result (this is a concept bug). Negative sextant index correction are not possible to input. And I get consistent result errors when cross checking output with my manual calculations.
