Description
#1 iPhone Utility in the App Store Sep 7, 2010
iStrobe is the first and best strobe light app on the App Store using the iPhone 4 camera flash. Fully adjustable strobe speed and flashlight mode. Extremely bright, iStrobe is a must have for any iPhone 4 user.
Simple in design, useful on so many levels. Defaults to a high intensity flashlight mode, but just drag the slider to the left to kick on the intense strobe light effects!
*** The reason why this strobe light is far superior to the others out there is that it implements a true rapid pulse strobe. If you have ever seen a real strobe light, you know it doesn’t just turn on and off at even intervals. It gives a micro-pulse of light followed by a brief delay. That micro-pulse and then delay is what you need to acquire a true trippy strobelight effect. ***
iStrobe as well as all our other apps are open source. Check out our website for more information and get started making your own iPhone apps today!
Continued use of the flash may dramatically decrease battery life.
