InfinitLight is the simplest way to use your iPhone 4 as a flashlight by using the camera's flash on the back. It also works on other devices by turning the screen white, which can be surprisingly effective in a dark place.

It was designed to prevent accidental input on the screen from disabling the light emission. As such, there is no button to turn the light on and off, no strobe mode, etc. Instead, just quit using the Home button or suspend using the Sleep button to turn the light off.

Also for this reason, there are no ads displayed on the screen — tapping them could affect the use of the app as a flashlight.

Finally, while InfinitLight is running, the phone is kept from going into sleep mode after a period of time to ensure the light stays lit. The status bar remains visible so that battery level and other information can be monitored during this time, though.

When used on an iPhone 4, the screen is darkened with a dark texture and an icon is displayed in the corner which corresponds to the position of the light on the back of the device.

Note: Use of the camera flash for extended periods of time can severely decrease battery life.

What's New

Version 1.4

Increased the speed of turning on the camera flash on devices that have one. InfinitLight should now be among the fastest flashlight apps in the App Store.

Note: This version requires iOS 5.0 or later. If you are running an earlier OS, you can continue to use the version you already have.

InfinitLight remains free, as it has always been. If you wish to support InfinitApps, however, you can do so by buying one of our other apps, as listed on our web page.

The ***BEST*** Flashlight App!!!

American Primitive

Please add the word "flashlight" to your title, i.e. "infinitlight flashlight" and you will quickly become the number one ranked flashlight and possibly one of the top 10 downloads. Why? Because everybody needs a flashlight, you have no serious competition whatsoever and "infinitlight" doesn't show up in a search for "flashlight".

I cannot tell you how many flashlight apps I've downloaded. Most were slow loading bloatware with ads that interfered with use and cumbersome add ons... All of which prevented you from getting the darn light on as fast as you could. The scant few that were workable offered updates that promised increased speed, big fixes, etc but only delivered slowdowns, complexity, bloatware and adds.

You have definitely nailed it. Instant on and easy off by power off by home button or power off. Great job!!!!

The actual fastest…that I found.

I second what TowHaul Utah said.

I have been finding so many flashlight apps that have been saying that they have the fastest light and whatever. But all of them that I looked at have a loading screen, but this one. Most of them have had Ads, why have those brightly colored ads when the screen needs to be as dark as possible so the flash can be as effective as possible. And so many of them cost money, this one is free. And, to top it all off, the icon looks nice, it isn't a cheesy icon like most of the apps of this type.

Simple, fast, no accidental shutting off


Unlike other flashlight apps with huge on screen buttons or ads that I always find myself hitting at the worst times (thus disabling the light), this has none of that.

Nothing on screen to accidentally kill the light. No pointless splash screens at startup. No delays at all. Hit the app icon, get light. Don't want light? Hit the physical home or power button. The quickest, simplest iPhone flashlight PERIOD. There's no reason to look for any other!
