BMI COMPANION

BMI icon with heart symbol on blue background.

Your daily health companion.


BMI Companion goes beyond simply calculating a BMI number. It gives you a clear, easy-to-understand view of your measurements, activity, and health trends so you can see where you are today and how things are changing over time.


Your Today screen brings the information that matters together in one place. See your current BMI and BMI category, understand the standard healthy BMI and weight ranges for your height, and view how your BMI has changed since your first measurement.


BMI Companion also helps you follow your progress without requiring constant manual entry. Record your weight and waist measurements when they change, while Apple Health can provide supported activity and heart-rate information automatically.


With BMI Companion, you can:


  • View your current BMI and BMI category
  • See the standard healthy BMI range of 18.5–24.9
  • See the corresponding healthy weight range based on your height
  • Track changes in BMI, weight, and waist measurements
  • Review progress across 7 days, 30 days, 3 months, or 1 year
  • Connect Apple Health for steps, active energy, walking and running distance, and heart-rate information
  • Switch between Imperial and Metric measurements
  • Review your measurement and health history
  • Keep manually recorded measurements stored directly within the app


Designed to Keep Things Simple


BMI Companion is intentionally focused. There are no complicated dashboards filled with information you don't need and no unnecessary health goals or motivational gimmicks.


The app is organized around two simple areas:


Today shows where you are now and how your measurements and activity are trending.


You gives you access to your profile, measurements, history, Apple Health connection, settings, and privacy information.


Built with Privacy in Mind


BMI Companion only requests access to the Apple Health information used by its features. Apple Health access is permission-based and remains under your control.


BMI Companion uses the health and activity information you choose to share to provide its in-app features. It does not use your Apple Health information for advertising or marketing.



Understand the Number. Follow the Change.


BMI is only one measurement and should always be considered alongside other health factors. BMI Companion doesn't try to diagnose you, prescribe a treatment, or replace your healthcare professional.


Instead, it does something much simpler:


It helps you understand your BMI in context, remember the measurements that matter, and see how they change over time.


BMI Companion — Your daily health companion.
