I developed a new Dash Julia application for body mass index (BMI) calculation. You can calculate BMI value and see the weight ranges. Feel free to review the codes on GitHub and ask me anything.
I am sorry to hear about height and weight ranges, it wasn’t my design, I just copied from a medical website. It’s possible to expand ranges, and add optional imperial units. I just tried to keep the app simple, so beginners can understand the code.
