Flash To Bang

This application is based on the method "Flash to bang" from where is, the name.
This method calculates the distance from you to the lightning ,based on time between lightning and the sound on current lightning.
The time is based on speed of sound in air, but it depends a lot from air temperature. The temperature range for selection in the application is between [1;46] Celsius or [33;121] Fahrenheit.
The distance to the lightning is calculated in three measurement units for length: Meters, Feets and Yards.

Instruction for using:
- This application is for Android 3.0 or higher!
- For proper calculation of distance you must to:
-- First: Select the air temperature from drop down menu top right!
-- Second: Press the button "Press at: Flash/Lightning" as soon as you see the flash(lightning)!
-- Third: Press the button "Press at: Bang/Thunder"as soon as you hear the sound of thunder from relevant lightning!
Congratulation you have the distance in the list, which is empty by default.

Бenefits and issues:
