BMI Calculator is a lightweight, privacy-first health utility that helps you
check your Body Mass Index and understand what it means. No sign-up, no ads,
no tracking — the app runs entirely offline and never sends your data anywhere.
Enter your height and weight, tap Calculate, and instantly see:
• Your BMI value with one decimal precision
• Your WHO category (Underweight, Normal, Overweight, Obese) with a color-coded scale
• A personalized healthy weight range based on your height
• How many kilograms you are above or below the healthy range
• A short, non-medical health tip tailored to your result
KEY FEATURES
• Metric and Imperial units — cm/kg or ft-in/lb
• Optional age and gender fields (not required)
• BMI history stored locally on your device (up to 50 entries)
• Beautiful Material Design UI, light and dark themes
• 100% offline — the app requests zero permissions
• Small install size and fast startup

PRIVACY
We do not collect, sell or share any data. Everything you enter stays on your
device. The app does not request any Android permissions and never connects to
the internet.
