SizeMatters+ uses augmented reality (AR) to measure anything in front of your iPhone. Using the camera screen, youll be able to draw a line and see the measurement of that line in centimeters, inches or meters. SizeMatters+ eliminates having to carry a tape measure with you at all times.
How to use:
1. Launch the app and wait for the red target to appear.
2. Tap and hold while you move your iPhone to draw a line.
3. Releasing your finger will end the line and present you with the measurement.
