Light Detector

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.

I too am totally blind. I’m so glad, and so is my spouse, that I can now help make sure all the lights are off at night!! ‘This is a totally awesome app!!!

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.

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)

I am blind and use this when I go visit other people or stay in a hotel. I'm able to make sure I have all the lights off for my guide dog. Even though I cannot see the light my dog still has problems sleeping with it on. I recently moved into a new house and have tons and tons of light switches in every room. This app helps me figure out which switch is for which light.
