Thunder & Lightning

By Bryan Figler

Open iTunes to buy and download apps.


Thunder & Lightning has (barely) one practical purpose: to measure your distance to a sound source. It works for thunder and lightning, fireworks, rocket launches, or other loud events visible from a (hopefully safe) distance away. Just press the Lightning button when you see the event, and Thunder when you hear it. Modern technology does the rest.

To perform this trivial task even more accurately, you can enter the temperature of your surroundings to more precisely calculate the speed of sound. You can also choose between U.S./Imperial and metric measurements depending on your personal unit preferences.

Should its intended purpose be insufficiently useful, this application can also be used as a reasonably precise (if redundant) stopwatch, a speed-of-sound calculator, a Fahrenheit/Celsius converter, or as an odometer if you happen to be traveling at precisely the speed of sound.

Note: Use of application while operating supersonic aircraft is not recommended or approved.

A Favorite Arrives on iPhone

Good app. Something similar was a favorite on my old Palm. Glad to see it on iPhone!

A few improvements:

(1) Having separate "Thunder" and "Lightning" buttons makes them smaller. Better for a single button of over twice the size to toggle between "Lightning" and "Thunder" with each tap, for easier operation while looking at the sky instead of the app.

(2) Allow typing the temperature. Much easier than dragging a slider.

(3) Should display the average time and distance of all records in the current log. This would average out errors in time in tapping the buttons across multiple lightning strikes, for greater accuracy in knowing the distance.

Fun for us weather geeks

Every time I know a thunder storm is approaching, I pull out my iPod and run this app. It beats trying to count out the seconds waiting for the thunder. The only thing I would change would be to have one large button vs. 2 small ones. 1st touch for the lightning and the 2nd touch for the thunder. The larger area would make it easier to watch the skies instead of making sure my finger is positioned over the correct button. Other than that, an excellent app.

You don't think it's practical?

Then you've never been riding across the midwest in storm season on a motorcycle, wondering whether you're going to make it to the next town before the violent thunderstorm that seems to be in all directions around you catches you outside of your Faraday cage, and when you're the highest metallic object in a quarter-mile circle. I personally think that the program is practical...
