The final distance can be calculated in miles, kilometers, nautical miles, yards, meters, or feet. Coordinates can be specified in and converted to and from decimal degrees, decimal minutes or decimal seconds. Bearing is returned in degrees true.

iOS 4.0 Tested

A video demo of how to move the pins is located here:

This pin jumping issue has been fixed in iOS 4.0, but for iOS 3.0 users, the difficulty of this depends alot on your screen protector. If the protector has a rough surface and causes your finger to jump around, the pin will be dropped often. You will get a better response if you move your finger slowly. Although, you should still be able to move a pin from the top to the bottom of the screen within 2 seconds without losing track. In iOS 4.0, this is not an issue.

Customer Reviews

Moronic user interface

Typical problems with engineer-designed UI. Not that engineers always are so tone deaf to users. Example: enter a long and lat (two very long numbers) and make a typo: the app tells you (with an exclamation point) that one of the the numbers (which one?) is "not a number" and then deletes both. Can anyone out there suggest a more user-friendly way of handling such an exception??

Not Backward Compatible

How can you sell an App that only works until Apple upgrades the OS. It should be backward compatible and users of older iPhones and older OS should still be able to use it. If you’re not going to keep it working for older phones you should refund the purchases.


Although its registered for Ipad also it's only for I Phones. I think the worst part about it is I couldn't get a refund. Won't be buying anymore apps from this vendor for sure.
