BMI – WITH AGE IN MIND
Gewko calculates your Body Mass Index (BMI) and displays the standard WHO classification for adults. It also provides age-related guidance based on a historical scientific BMI reference table.
Scientific sources are explained directly in the app. The age-related ranges are not universally accepted medical thresholds. Gewko is intended for personal information only and does not replace professional medical advice.
