If you find yourself in a situation where you need to measure an object but you don't have a ruler with you, then iRuler HD is here to save your day!
All you have to do to measure an object is place it on the lower left corner of the screen, tap where you want to measure and you will be given an accurate readout of the size of your object in inches or centimeters.
Other features of iRuler HD include:
With iRuler HD you can save up to 20 past measurements at one time. Just tap the save button next to the screen to save your measurement, then, when you need it again, tap the readout screen to get a list of all of your saved values.
If you want to make sure that the measurement you currently have doesn't change, simply tap the lock icon on the top of the screen and no more measurements will be taken until it is tapped again, unlocking the screen.
If you have an idea for something or just need to draw on the screen for some reason, just tap the pencil icon at the top of the screen and you will now be able to sketch all over the screen. If you need to clear what you have drawn, simply double tap anywhere on the screen.
