LED Light for iPhone 4

Introducing...LED Light for iPhone 4!
The iPhone 4 comes with a super bright LED for flash. Why not use it as a flashlight?
The app also includes an adjustable strobe light mode:

I am so glad that somebody cracked this one. Sony Erickson has had this as standard software on their phones for a while, and NOKIA has finally come around too!
Thanks for making this available to the APPLE community. Look forward to using it tonite!

Thanks for making an iAd version. Love this little app. I caught this one just in time. I know .99 isn’t much but free is always better.
July 7th, 2010 at 3:23 pm
Great app. Well worth the $0.99.

Love the light app. That LED is bright and the strobe feature is nice for attention getting.
If you are able to pulse the LED fast enough, you could pulse width modulate it and have an brightness control…… maybe a slider on the screen to dim/brighten the LED. That would also help battery life since you could run it at half brightness if you didn’t need full brightness.

You could have an ‘SOS’ strobe, it may not be used very often, but imagine one person lost on a boat with an iPhone 4!

Can the flashlight app ever adjust the amount of light? Or are the LEDs all or nothing?
Keep up the good work!
July 9th, 2010 at 9:06 pm
@chaz – The API only allows for on/off. I’m not sure if Apple will be updating it to control the intensity of the light in the future.
July 11th, 2010 at 5:08 am

If you are able to turn the LED on/off at a few hundred Hertz or faster, then you can adjust the brightness with the duty cycle. The LED would still come on full brightness, but the eyes/brain would average it out.
July 12th, 2010 at 2:29 pm
Jason,
You really must add a button to allow the light to continually strobe SOS in morse code. I am a Search and Rescue pilot and can tell you that this app could save the lives of people lost at night – using NVG we could see the strobe from over a mile away! Do it – you could really make a difference. Andy

Hi,
I want to make a flashlight app for my summer school project, how do I go about to activate this feature in my iphone 4? It seems like a simple app to make for a summer course, can anyone point me in the right direction, what API do I have to read up on to make this app? Can anyone email me a sample code so I can study it please?
Thanks for all your help

Love the app. Would like to see another button that turns the light on only when you touch it, but turns off when you stop touching the screen. This would enable you to use the light for signaling or morse code.
July 27th, 2010 at 2:23 pm
Great and usefull App. Would be nice if you could implement a timer. So that the LED / App. closes itsself after a period of time.

Love the app, tried to find the paid version, but it doesn’t seem to be on the app store anymore?
August 22nd, 2010 at 9:01 pm
Hi,
Does the app turn off when the auto-lock kicks in?
August 23rd, 2010 at 6:53 am
Since updating a couple days ago, the application doesn’t work at all. Any remedy?
August 24th, 2010 at 9:49 am
@cshander – I removed the paid version from the store because maintaining two versions of the app was going to be too much trouble. Since a few people have been asking for it, I’ve put it back on sale, but I won’t be updating it.
@marie – The app disables auto-lock.
@drew – Try force killing the app from the task switcher menu, or power cycle your phone…let me know if it works.
August 26th, 2010 at 6:37 am
The app is excellent but the free ver got update to 1.2 and the paid ver is still 1.1 hope there is an update soon cos I really like the SOS feature. Good job though it’s nice and simple app.
August 31st, 2010 at 5:10 pm
@drew: try killing the app from the task switcher. it that doesn’t work, try power cycling your phone.
