iLightningCam 1.2 allows you to capture a lightning strike using the 8-megapixel camera of the Apple iPhone 4S. In full-resolution mode, the app builds on the increased speed of capture offered by the iPhone 4s, which “should capture almost all lightning strikes within range”, the developer says (the app works on the iPhone 4 too, but fast lightning strikes might be missed “due to hardware limitations”). iLighningCam 1.2 also works in video mode, where it analyses the footage and grabs the frame in which the lightning occurs and saves it - along with the next one - as a JPEG with a resolution of 1280x720 pixels on the iPhone 4 and 1920x1080 pixels on the 4S. The app is available on iTunes for $0.99.
