Project Overview & Architecture
BMI Calculator is a clean, single-screen health utility that lets users find their Body Mass Index in seconds. Height and weight are set with smooth metric sliders (100–250 cm and 30–200 kg), age is picked from a scroll wheel and gender is chosen with a single tap for better accuracy. One tap on Calculate BMI opens a colour-coded result screen that shows the BMI category, a personalised lifestyle recommendation and a summary of the entered details, with options to recalculate or share the result.
