Haircut visualization tool

Hello, I am sure you all must have heard of the Haircut visualisation tool at some point. I have been working on one and have designed a tool specifically for barbers. Just wanted to check with the barber community on what you think of such a tool.

I have connected with multiple barbers and came across that miscommunication is really an issue in barbering. Do you think using such a tool would help you and your clients have the same expectations before you start a haircut? Also, most of the barbers are not using such a tool, so do you think using it would give you leverage over other barbers to attract new clients?

I would love to hear your opinion on that since it would help me draft the future of my Venture.
