GPS location :

This app uses your GPS location to locate lightning Impacts. Press the green button to get your GPS location. If GPS doesn’t work properly, you can either choose not to use GPS. In this case, your GPS location will be set to (0,0). You will still be able to use lightning maps, but lightning gps location will be given as an indication.

Basics :

A flash of lightning, followed after some seconds by a rumble of thunder is, for many people, the first illustration of the fact that sound travels significantly slower than light. Using this difference, one can estimate how far away the bolt of lightning is by timing the interval between seeing the flash and hearing thunder.

Press the green button when you see a lightning, press it again when you hear thunder.

Altitude :

To calculate the altitude of lightning, hold the Palm in front of your eyes towards the lightning….

If the flash is over the screen, you must reduce the distance between your Palm and your eyes.

When lightning strikes, use the ruler on the side of the screen to measure the height of the flash. Lightning Impact calculates for you the lightning altitude !
