BMI Calc: BRI, No Ads on Windows Pc

BMI Calc is the BMI calculator that respects you: no ads, no tracking, no account — plus modern metrics that go well beyond BMI and real growth percentiles for kids.

No ads. No tracking. No account.
• No advertising of any kind, anywhere in the app
• No analytics, no tracking SDKs, no profiling
• No sign-up and no cloud sync — we run no server that stores anything you enter
• Your weight history and body measurements stay on your device
• The app contains no networking code of its own; the only component that can reach the network is Google Play Billing, and only if you choose to buy the optional unlock

Cut-offs that fit you
Optionally switch to the lower WHO action points used for Asian populations (overweight from 23 rather than 25). Your choice in settings — the app never guesses.

Beyond BMI
BMI alone can be misleading. Enter your waist circumference and get the metrics researchers actually use today:
• Body Roundness Index (BRI) — the "BMI successor" from recent studies
• Waist-to-height ratio (WHtR) with NICE guidance bands
• Body fat estimate (US Navy method) incl. fat-free mass and FFMI
• Classic BMI with WHO categories, healthy weight range, "new BMI" (Oxford) and BMI Prime

Made for the whole family
For children and teens, adult BMI categories are simply wrong. Set a birthday and the app switches to BMI-for-age percentiles and z-scores from the official CDC growth reference (2–20 years), bundled with the app so nothing is fetched.

German users get the Kromeyer-Hauschild reference and the AGA thresholds instead — the one German paediatricians actually work with, covering birth to 18. Switch either way in settings.

See the trend, not the noise
Daily weight swings by a kilo or more from water alone. The app draws a smoothed trend line through your weigh-ins and bases your weekly rate and goal forecast on that trend rather than on two lucky readings.

Goals that are honest with you
Set a target weight and an optional date. The app splits it into milestones, tells you whether you are on track, and projects your arrival from your actual current pace. If the date you picked would demand an unhealthily fast loss, or the target would put you below a healthy BMI, it says so instead of cheering you on.

Track what you measure
Log your weight in seconds, with waist, neck and hip alongside it. Premium adds the trend chart, statistics, goals with milestones, CSV export and import, and a homescreen widget.

Yours, privately
Optional app lock using your fingerprint or screen lock. Export your full history to CSV whenever you like and import it back — your data is not held hostage.

Ideal weight, honestly
Devine, Robinson, Miller, Hamwi and the Broca index side by side. They disagree by several kilos, and you get to see that, with the healthy BMI range next to them.

Modern Android
Material You dynamic colors, light/dark theme, AMOLED pure-black mode, homescreen widget, metric, imperial and stones/pounds units, fully localized in English and German.

Premium is a one-time purchase, not a subscription.

Note: This app provides wellness information, not medical advice.

• Smoothed trend line — your rate and forecast come from it, not one lucky weigh-in
• Goals with milestones, pace and a warning when the plan is unsafe
• Kids' percentiles: CDC or Kromeyer-Hauschild
• Stones, Asian BMI cut-offs, CSV import, app lock
• Bluetooth scales (beta)
