Some users have reported inaccuracies in the ruler scales on the image.
To overcome this use the Calibrate Button in the upper left. Have a real ruler on hand for a one-time setup.
Your settings will be saved from each use so you don't have to redo the calibration each time.
If the ruler dimensions on the display are not matching up to a real ruler do the following:
1) Hold a ruler up to the scale and note if the image is larger or smaller than the ruler.
2) Press Calibrate
3) Pinch the image larger or smaller as needed.
4) Press Save
5) Check again with the ruler. If still off repeat steps 1 - 4

Nice app The calibration update is excellent. Beware if you use a battery bar app...it will throw off the calibration; so it must be disabled for the setting the calibration and properly applying the calibration. Hope everyone is willing to put melting hail near their electronics!
