Have you ever wondered how far away from you a thunderstorm is? In that case, ThunderTimer is what you have been looking for! ThunderTimer calculates how far away a lightning is based on the difference between the speed of light and the speed of sound.

ThunderTimer will also give an indication of whether the thunderstorm is moving away or towards you. ThunderTimer supports both U.S. and metric units for measurement. ThunderTimer can of course be used to measure similar events, like fireworks and others. Additionally, further development goals are to use the integrated compass in IPhone 3GS together with GPS localization to pin-point the location of the lightling on a map. Another further enhancement is to log the measured distances.

Pros and cons of ThunderTimer app for iPhone and iPad

ThunderTimer app good for

I like this app. It tells you how far the lightning is away. Something great for me to do during thunderstorms when I cant use my computer on other electrical appliances.
Somehow with that review I get the feeling he thought that you run the app, theres lightning and the app just does the figuring for you because it "senses" the lightning, lolololol Dude, this works fine and as I type this, its free. I hope you dont run accross an app for your toilet. Lives could get out of hand....
App is basic, but works well. Hope for an update before rainy season starts here in Texas! In my opinion, the interface is quite bland. Description should be moved to top or bottom away from button. "see a lightning" should be rephrased "see a lightning bolt/strike/etc," and a period couldnt hurt.  Pull button colors from native iPhone apps to give it a more seamless, integrated look. You could also add some lightning safety tips to give some meat to the app. I dont know what people expect this app to do (stop a storm?) but some reviews are...not helpful. Try the app for yourself and give a useful rating based on what the app is designed for.
The tool is designed to provide a measurement regarding the distance of thunderstorms. It does this function well and nothing more. I think it downloaded without any additional expectations, it is a great application.

Some bad moments

Im in CA, and I get thunderstorms. it is fake and it doesnt work so, dont wast your time downloading it
Why would you want to be holding a connected iPhone in a lightening storm? And can you count to five without a timer? Sheeeesh.
This app would be really great if it used the light sensor that controls auto LCD back light dimming and the camera on an iPhone to detect the lightning. As well as use the microphone to listen and detect the thunder. This would be great for setting up a lightning auto detection logging ability that would log the time, location and estimated distance. It could also pull weather data off the net to determine the local temperature to increase accuracy. You could also use the compass of the 3GS to auto or manually input the heading of the lightning. Then you could actually plot the estimated location of the lightning on a map in the app.
