Leave a Review Great Circle Tool
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.
