iStrobe - Flash & Strobe Light for iPhone 4

By Nick Vellios

This app is only available on the App Store for iOS devices.


#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.

Good app

I like utilitarian apps, so this was right up my alley. It is undoubtedly the best strobe light app out there. The adjustable speed feature is really nice, and it is also very simple to use. The only problem I have, and the reason it got 4 stars, is that the light quit flashing when your phone goes to sleep. I used this to slow down traffic one night at the scene of an accident, and this was a real pain. Otherwise, love the app!!!

Great strobe

This strobe light works the best out of the ones I have tried. One thing I did to test the strobe effect is waved my hand behind the phone to see if I got the motion stutter effect and this was the only strobe that looked like a real strobe light was on.

It would be nice if it had a music strobe feature (strobe music) and if on/off was a separate button from the strobe slider.

True strobe setting

Good flash light and this is the only app I've seen that actually does a real strobe effect. Most apps to a slow flash even though they consider it fast. Turn out the lights and set the fast setting with this and you have a real strobe light. For free too. 5 stars.
