Editor's Review
This is a single-purpose tool and it is honest about that. Enter height and weight in metric or imperial units, and BMI Calculator returns your body mass index, the range it falls into, and a target weight for a healthier band. Entries can be saved, so the number can be watched over weeks instead of checked once and forgotten.
Worth knowing before you read anything into it: body mass index is a crude measure. It accounts for nothing beyond height and weight, so muscular builds read as overweight, frame size and age are ignored, and it says nothing whatsoever about where fat sits on the body. No app can repair that, and this one does not pretend otherwise. Treat the output as one rough signal, and take anything that worries you to a doctor rather than to a phone.
