Step 1
Place your phone on a flat surface. Stand up and look at your phone from a birds eye view.
Step 2
Place any bank or credit card on the card image you see on this screen. Adjust the black outline by sliding the circle at the bottom of the screen to the left or right. The black line should border the card but still be visible.
Then click 'Next'.
Choose between the two options below.
Place your ring on the circle and line up the black outline to the inside of your band.
Use a string or thin piece of paper and wrap it round your finger. Mark the length or cut where both ends meet.
Then place it on the blue line & adjust the length accordingly.
