BMI Calculator - Metriva

Log your weight, get your BMI instantly, and watch the trend that actually matters take shape over time.

Metriva turns a one-off BMI calculation into a body-progress tracker you will actually keep using.

Enter your height once. Every time you record your weight, Metriva works out your BMI, plots the trend, and shows whether you are moving toward your goal — without the ads, social feed or calorie-counting homework of a full diet app.

WHAT YOU GET • BMI calculated automatically from every weigh-in, with your category and healthy range • Weight trend charts across weeks, months and the full year • Body measurements: waist, chest, hips, arms, thighs and more • Private progress photos with a side-by-side comparison view • A goal weight with a clear read on how far you have left • Weigh-in reminders so the habit sticks • Apple Health sync — import your existing weight data or write new entries back • Metric and imperial units, switchable at any time

BUILT PRIVATE Your weight, your measurements and your photos stay on your iPhone. There is no account to create, no cloud upload of your pictures, and nothing you record ever leaves your iPhone. Progress photos are held in protected local storage.

DESIGNED FOR THE LONG RUN Recording takes seconds. The charts make the direction obvious even when the daily number bounces around. Everything is built around the one question that matters: over time, is this going the right way?

SUBSCRIPTION Metriva Premium unlocks the full dashboard, history, measurements and progress photos. It is offered as a yearly subscription with a 7-day free trial, or as a weekly subscription. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel yours in your Apple Account settings.
