Found a glitch
Sulphur Molten UN 2448 can be classified as class 9 or class 4.1 the app only shows class 4.1

Good but needs help
Data is easy to find. However, plume map pin can’t be moved nor is entering lat and long manually accurate. More than a mile off. This is a critical component when determining a valuation and downwind concerns. FIX IT

Great tool!
Was easy to use and quicker than thumbing through the book. Would like to see the ability to drop the waypoint on the map when plotting isolation distances, currently you can only input addresses. Also, the text bubble used with the waypoint does not display entire text, even when screen is rotated on iPhone 7.
