Calculate distance of lightnings and find out how far away the storm is. This app calculates distance using difference between speed of light and sound.
Just tap a button when you see the lightning and then again when you hear the thunder and the app will tell you how far away it is using a time difference between the two.

No input from lightning sensors... relies on user to click when the see lightning and click when the hear the matching thunder... in most cases if one sees lightning they should have already taken shelter so I’m not sure what the purpose of the app is... i suppose having a stopwatch gets the distance calculation more accurate but to what end? Knowing the lightning struck 2 miles away versus 3 still means the same thing, get off the fricken golf course/out of the pool/ etc and take shelter...
This app is so great I grab the first time well
