App Description

An advanced measuring app using your iPhone camera
Smart Ruler can accurately measure distances up to 15 metres - 50 feet.

All you need is your iPhone and a standard size sheet of paper (A4/US Letter) or an iPod touch/Smart phone

Fantastic for finding out the height of a tree, the area of a room or even the size of you TV screen.

The application uses the camera in real time. Take your photo and tap the target, distance will appear automatically. Sights can then be adjusted for measuring horizontally, vertically and diagonally. You can then zoom in/out - very easy to use.

Each screen, displaying measurements, can be saved to photo library or emailed on.

Works on all iPhones
