LED Light for iPhone 4
Monday 06/28/2010 – Category: Uncategorized
UPDATE: All new version featuring adjustable brightness mode and support for iPhone 5!
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:
A video from a beta tester (thanks Michael!)
Update 7/7/10: The app has been approved!
Also, a free (iAd supported version) is available for download here.
Note: If the app stops working for some reason, try manually killing it from the multitasking menu or hard restarting your phone - I'm investigating why this happens for a future fix.

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!

Honestly, this is the best application ever. I have been using it daily since I got it and cannot wait to get the official version once it is available in the app store!

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.

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.
July 9th, 2010 at 5:14 am
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.
September 4th, 2010 at 10:21 am
I bought the app today and now i see that the free version is getting some updates but the paying one no
Would it be possible to update also the paying version? Or at least, removing it from the store in order to avoid confusion…i wouldn’t have bought it if had known there wouldn’t be updates!! I would really appreciate the SOS feature!
Thanks
Albert

1) It seems a bit wrong to not provide updates for the people who DID pay for the app.
2) Does everyone like the new settings symbol in the app? I find it takes away from the simplicity of the app. Wouldn’t it be better to have the options in settings, with another option of havin the options accessible from the app?
3) I really like the app, I think it’s by far the beat flashlight app available in both aesthetics and functionality.
September 8th, 2010 at 7:50 pm
@Will and @Albert: I’ve updated the paid version, look out for the update in the next week – thanks for your patience.
September 14th, 2010 at 10:59 pm
Thank you.
September 15th, 2010 at 2:49 pm
Glad to hear it about the paid version. I just paid for it to show you some love to what I believe is a wonderfully executed, simple app. I tell everyone I know about it.
Please consider putting something in the description informing potential buyers of the lack of future updates. Will the forthcoming update for the paid version be the last?
September 16th, 2010 at 9:06 am

Hi Jason-
Good work on the app. Definitely agree w/ Will re: the form- best looking flashlight app out there.
A new functionality suggestion: can you develop a way to use either the LED light (bright lighting) or the monitor “light” (low lighting)?
Thanks, and keep up the good work.

Hi Jason,
I’d love to use the app but can’t get it to work…the light simply won’t turn on. Have tried the flash and it seems to work. I’m using an Iphone 4 with the latest software installed. Thanks for your help.

@Philip – Have you tried power-cycling your phone? That seems to have done the trick for some people.
October 4th, 2010 at 8:44 am
the great thing about LED light is that they do not generate lots of heat~~;
October 18th, 2010 at 5:05 pm
The app works well but the first version ( I guess 1.1) worked great. As soon as you hit the icon the LED would come on immediately. Since version 1.2, that adds other options to customize it takes about 2-3 seconds for LED to come on after LED light screen pops up. Can you fix this or just make other version available again. I just want LED to work. On and Off. Thanks. Otherwise good app.
November 9th, 2010 at 12:16 pm
Great app BUT mIne worked fine for a few days and now it will only flash. No continuous light possible. Any ideas?
November 10th, 2010 at 2:34 am
The app did work 2 times and not more
November 23rd, 2010 at 11:11 am
your application is out of order with iOS 4.2 ! impossible to lauch the flash !
February 26th, 2011 at 1:10 pm
Nice App. What would make this exceptional would be the ability to type in letters/words/phrases & let the App convert it into Morse Code.
You’ve already done ‘O’ & ‘S’, just another 24 letters and 10 numbers to go
October 13th, 2011 at 1:40 am
What about hotel mode? set the app before bed and during the night just by moving or picking the iPhone the light is active, great to find the bathroom or in an emergency
November 7th, 2011 at 8:06 am
Thankx a lot for this great app.
December 18th, 2011 at 7:42 pm
Where did the app go? I can’t find it in the app store. Thanks.

Just installed your app. Wondering what the sleep timer does?
May 15th, 2012 at 11:15 pm
It will turn the light off automatically once the time interval has completed.
July 14th, 2012 at 2:06 am
LED app has very good write ups, but when installed on my iPhone4 with iOS 5.1.1, i can’t get the light to switch on? Using camera, the flash works fine. Have tried a power cycle – still not working. Any ideas please?
September 5th, 2012 at 10:39 pm
Wonderful app! I purchased it without hesitation. I love the functional simplicity.
HOWEVER, I have one request. Please please please please remove the data.flurry.com communication from the paid version. I understand the value of using analytics in a free app. However, for a paid version, I would much rather have a flashlight app that does not communicate device identification codes each time I run it…
Thanks again for the outstanding app. I have recommended it specifically to several friends.

Is iOS 6/iPhone 5 and brightness control coming anytime soon?
November 4th, 2012 at 6:34 am
Please update the really nice App for iOS 6/iPhone 5 display!

Hey is iPhone 5 support coming anytime soon?
