Is your weight in the healthy range? Drag two sliders — height and weight — and BMI Calculator answers in seconds: your body mass index to one decimal, the WHO range it sits in, and the exact weight band that counts as healthy for someone your height. Most BMI apps hand you a number and a colour. This one shows its working. Every category is labelled with the standard behind it — WHO international (18.5 / 25 / 30) or WHO Asian-Pacific (18.5 / 23 / 27.5) — and the cut-offs, healthy ranges and disclaimer all cite WHO, CDC and NIH sources you can open from inside the app. You always know whose chart your number is being read against. WHAT YOU GET • Your BMI recalculated live as you move the sliders — no Calculate button, no account, no waiting • The range your number sits in — underweight, healthy weight, overweight or obesity — with the printed cut-offs right under it, so 24.9 and 25.0 never share a label by accident • The healthy weight band for your height in kg or lb — see exactly how much sits between you and either edge • A history chart with the category bands drawn behind your readings — spot the month you crossed a line, not just today's number • An optional waist slider that checks you against the NICE keep-your-waist-under-half-your-height guideline • Every reading saved on your phone, with editing, swipe-to-delete and CSV export when you want the raw numbers PERFECT FOR • Anyone whose doctor mentioned a BMI number and wants to watch it move between visits • People of Asian descent — switch to the WHO Asian-Pacific cut-offs (23 / 27.5) that international wall charts ignore • Imperial and metric users alike: 5′ 10″ and 178 cm are the same slider, and switching units never corrupts a saved reading • Households where more than one person steps on the scale — each person gets their own profile, height and history WHY NOT JUST SEARCH FOR A BMI CHART? A wall chart tells you today's number and forgets it, rounds you into the wrong box, and never says which population its cut-offs were written for. This app keeps your history, classifies the same rounded value you actually see, names its standard on every screen — and a weekly check-in reminder makes sure the log actually gets filled in. PRIVATE BY DEFAULT No account, no server, no analytics or advertising SDK. Nothing you enter leaves your phone unless you export the CSV yourself. The app does not touch the camera, microphone, location or your health records. FULL ACCESS Full Access unlocks profiles for every person in your household, each with a separate history and chart. Choose a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. BMI is a screening measure, not a diagnosis — the app says so on every result, and it means it. Download BMI Calculator and know where you stand before your coffee cools.
