Have you ever listened to light? With Light Detector, now you can!
Light Detector transforms any natural or artificial light source it encounters into sound. Light Detector is easy to use! Just run the application and point your iPhone camera in any direction. You will hear a higher or lower sound depending on the intensity of the light.
If you are blind, Light Detector helps you to be more independent in many daily activities. At home, point your iPhone towards the ceiling to understand where the light fixtures are and whether they are switched on. In a room, move the device along the wall to check if there is a window and where it is. You can find out whether the shades are drawn by moving the device up and down.
Bring Light Detector with you to discover what is around you at the speed of light.

Does one thing, but does it well

As a totally blind person, this app is wonderful for telling whether my environment has enough light to take decent pictures with TapTapSee, or to call Be My Eyes. Great thing to have among my utilities.

Deceptively simple

This app makes a low humming sound when you open it in a dark room, and the sound changes pitch depending on how much light the camera sees. When I first opened it I thought it wouldn't be that useful, but I just didn't realise how many things are indicated by a little light. I've used it to tell if an old cell phone was charging, if the coffee pot was on, if a light was burned out, if the kids had the light on in their room after bedtime, and even if a stick of incense was still burning. It's very sensitive and reliable.

Simple, effective, uncomplicated does it

As Chuck Berry has been reported to have said:

"Keep it simple ...."

For a totally blind person, this app allows detection of light at various levels. If a light has been left on or not turned on, the detector indicates this by its tone: low for low or no light and high for bright light, with gradations according to the light source. The app lets the user know if a bulb has been burnt out or whether someone in the house has, or has not, forgotten to open or close blinds or curtains.

Works every time without fail on my IPhone 4.
If you want to play with it, you can engage the app, scan the phone across a solid object, such as a standing person and the tones will warble and oscillate. Just tell your subject that they have confirmation that they have not been transformed into an alien. (smile)
