The Wonders of Technology
Here are some VERY cool iPhone apps I found – and relatively cheap, too!
LookTel Money Reader ($9.99): recognizes currency in real time
SayText (free): scans text in image and reads it out loud
Color Identifier ($1.99 or free): identifies and speaks specific color names. It can also distinguish specific color shades of the sky (sunsets, cloudy)
Light Detector ($0.99): emits a sound which intensifies as a light source is found and approached. (For example, to find the nearest exit.)
