## What is LRuler?

Turn your iPhone into a precision L-shaped ruler. Place it flat on any object or hold it against an edge and read accurate measurements off both display edges - horizontally and vertically at the same time.
                                               
For whenever you don't have a ruler or tape measure at hand.                                                            
  
Simply place your iPhone on or against the object you want to measure. The L-shaped ruler lets you read two dimensions at once - accurate to the millimetre.
