Simple BMI evaluator

Enter your weight and height to see your Body Mass Index. The result updates as you type.

Designed to work with VoiceOver: every field and button has a spoken label, your BMI is read together with its WHO category, the healthy weight range is read as a full sentence, and weight changes made with the +/- buttons are announced.

Supports Dynamic Type: text and the BMI scale follow the text size chosen in iOS settings.

WHAT IT SHOWS
• Classic BMI and Trefethen's revised BMI (Oxford, 2013), which fits very tall and very short people better
• WHO category, from severe thinness to obesity class III
• The weight range that counts as normal for your height
• A color scale showing where your value falls

ALSO
• Kilograms and meters, or pounds and feet
• +/- buttons to adjust your weight without retyping it
• Share the result
• iPhone and iPad, no account needed
