A very good and useful tool, needs a few things. – Drone Buddy: Fly Drone Safely Review

A great tool for drone pilots for a basic reference, paying to remove ads helps A LOT but if you don't want to pay it's usable. Phone numbers for most airports are listed if you need to gain permission however some of the descriptions don't display properly. OverAll it's really great but more information would be helpful.
