This makes it easy to look up the placard numbers you see on tank trucks, etc to see what they are carrying. That way those of you who love to tailgate because you failed grade school science and have no idea why physics says tailgating is a bad practice can see which trucks you REALLY don't want to be too close to. A native iPad version would get 5 stars...

Love having the app on my phone. Great guide. Easy to locate materials. Would like to see a quick phone number guide on the front page in case of an emergency.

This indicates it is compatible with iPhone AND iPad. I initially purchased and expected it to be downloadble for both. Instead I had to pay for iPad version also! This shouldnt require DOUBLE Purchase unless clearly specified!!!! I want to use both and a refund for one!!!
