User reviews

Appears to be unmaintained; broken.

I bought this tool to see which cities were under a great circle between two points. Unfortunately, even though you request “Cities” in the settings, you get nothing. Furthermore, if you open the “About” page, it displays a blank screen, and when you then go back, the display is trashed. The only way seemingly to recover is to close the app and reopen it.

This has all of the earmarks of a neglected, unmaintained app.

Completely useless

Can't measure location between two points. Can't even define a point except by text entry. Offers to show city names but there are none. Developer appears dead at the helm.

Excellent pilot app

It simply works great and will work at altitude with no internet connection. Very useful.

Not bad but crashes

Only works showing miles. Instantly crashes when trying to switch to kilometres..... App is clearly not supported by developer.

Great circle tool

Do not purchase this app. It only can map two locations at a time, unlike the pc/mac program that can map multiple sites. The app crashes when you try to change settings. No resource to lodge complaints or request refund. Will challenge cost with CC company.
