Magnifier Free – Magnifying Glass – Flashlight is a handy app for reading and viewing images that are magnified. The magnifier is powered by the phone’s camera, so you can use your phone’s camera to magnify the text and images on any kind of paper or digital image. It also works as a flashlight since it can be turned on or off with a single tap.

The magnifier is a useful tool for reading, especially for people who have low vision and for those with macular degeneration. It is also a good magnifying glass for shooting and for taking photos of small objects.
