Awesome! Best one yet. You can adjust your distance units. Is simple and easy. The graph idea is great. And accuracy is pritty close. You should add a temp variable for more accuracy. :D

Thunder calc rules Remember to try to standardize your Reaction Time. After the "flash" you are "primed" to a faster reaction than before, as you are waiting for it. Buttons are big enough for accurate.first time strike. Yeah, I like it!

Simple and accurate Does the job well, press the lightning button when you see lightning, then press the thunder button when you hear thunder! There's even a map showing the area where the lightning could've struck.

Great Aside from the fact that I love thunder storms. It is really convenient to be able to accurately gage how much time you have before thunder is on top of you.

Blitz The very best. I would like to store events by date. Top left of screen needs tidying to give symmetry to top line.

Simple but effective Good user interface. Graph and map lightning location donut quite clever. A good stormchasing tool to add to my arsenal.
