Visor is a magnifying glass for your iPhone, iPad and iPod touch. Enlarge difficult to read text by 4 magnification levels and change contrast to 5 different viewing modes. Optionally, turn on the LED flash of your device to help you see better in low-light conditions.
Visor for iOS supports AirPlay for streaming your magnified content to your TV and VoiceOver.
During the day, there is a lot printed text to read:
- restaurant menus,
- price tags,
- the newspaper,
- letters or
- photos from your loved ones
visor zooms and improves the contrast of whatever you want to see. Its advanced color modes and simple interface are made for giving you the best possible perception of printed text on your screen like you'd expect it from a handheld electronic magnifier.
