I will be adding prompts to adjust screen size, different string lengths (violin now), labels for the frets, and other than tempered intervals.
If you want this to scale, where does the red mark show on your ruler?
How long are/is your open string(s):
If necessary, enter fraction and press TAB like "3/16":
The fraction thing is used to convert fractional inches to decimal. If your open strings are 25 9/16" long, enter
9/16 in the fraction box and press the TAB key. You can now answer 25.5625 in the open string box.
