Lupa works as a convenient magnifying glass to help you see small print better using your phone. It accesses the camera on either the front or the back of your mobile device. The phone camera then works to enlarge the print or object that you were trying to see. This program is very helpful for anyone who suffers from a vision impairment or needs to have print enlarged in order to read it. Another benefit of this helpful program is that it provides instant access to the flashlight feature on your phone to also help you see better in the dark.
