Why no way to avoid ads?

First I should say I don’t open this app often. I used to like the clean simple interface and beautiful design. Now when I open it there are ads and I don’t see a way to upgrade to get rid of them. I may be going batty but I really don’t remember seeing these ads before. Probably won’t keep this app because of it, since I can’t make them go away - spoils the uncluttered experience.

Good, with a couple bugs.

The application apparently is displaying the longitude incorrectly--East and West appear to be swapped in the display. Auto works, but is confusing because of this swapping.

When using 12-hour time, the times do not fit in the text boxes and show "..." instead of AM or PM.

When doing manual lat/lon entry, switching between lat and lon does not use the current setting for that coordinate.

I like the new page with "next..." phases. Nice addition.


Diana delivers

After setting up using the iPhone GPS, I checked the calculated numbers against the U S Naval Observatory. Diana is precise. No problems as earlier reported - must have been corrected or not caused by the app. Thanks for a great free app!
