This does not exist yet
You clicked A range sheet for a whole choir. Nothing was sent, nothing was signed up for, and there is nothing to buy on this page. It is not built.
What it would be
Measure twenty singers in one rehearsal, get a printable sheet of everyone's two notes, and a suggested section for each that you are free to overrule.
Price if it existed, about 9 dollars, once.
Why I put it in front of you
Because a director measuring a room has a reason to pay that a curious singer does not.
Why I am doing it this way
I have been improving a tool that nobody has a reason to buy, and asking people what they would pay for gets you polite answers. Clicking a priced option a second after seeing your own result is a slightly more honest signal, so that is what I count. Your click is a number on a page, nothing else. I do not know who you are and I would rather keep it that way.
If you want to say something a click cannot, the address is thibaudlepanpro@gmail.com, and a sentence about what would actually help is worth more to me than the click.
