Add measurement to the list of things your iPhone or iPad does well. With iMeasure, it becomes a 2-dimensional ruler and SAE/Metric converter.
The tools:
Measure: The Measure tool allows you to lay an item on the screen, and move an indicator to measure its dimensions. Plus, the instantaneous readout is in decimal inches, fractional inches, and metric millimeters.
Ruler: The ruler tool is different from the Measure tool in that the device itself is the ruler, with zero inches being the bottom of the device. Use a protective case for you iPhone? No problem, because the ruler can be calibrated to account for the case.
