Please remember to calibrate the tool for most accuracy. “Measure Ring Size” > “ Calibrate” at the bottom right and follow prompts
This app is designed to measure your ring size accurately and consistently every time.
Simply place your finger between the black lines. Press lightly against the screen and do not squish the bottom of your finger.
Use the dial at the bottom of the screen to resize the black lines to fit your finger.
Once you feel comfortable with the size release the dial and let us do the magic. The final size will appear in green font once we are done scanning.
Note: The measurements are highest in accuracy on iPhone devices.
