BMI calculated, not categorised
Your BMI is computed and shown with its formula. ONU does not attach a risk label to it, because the supplied model disagrees with itself about where the boundaries sit.
A number that means more with context.
YOUR OWN ANSWERS
The weight and metabolic questionnaire
Nine questions about your history and nine about how you eat and move. The second nine can lower the score as well as raise it, which is the point: the model was built so that the things you can change actually move it.

This is the questionnaire domain of ONU’s own model. It is not a diagnosis, and it says nothing about body composition — what you are made of is not in these questions.
What you walk away with
Three things, in about five minutes.
The habits that sit underneath it
Activity, sleep, diet pattern and alcohol are captured alongside the number, so the picture is about how you live rather than one measurement.
A route to real support
If clinician-led weight management is what you want next, the eligibility and assessment steps are set out plainly rather than sold.
What it looks at
Nothing hidden behind the result.

How it works
Three steps. No sign-up to begin.
- 01
Start with the measurement
Height and weight give you BMI immediately, with the arithmetic visible.
- 02
Add the everyday context
The lifestyle chapters take a few minutes and matter more than the single number.
- 03
Choose a next step that fits
Keep tracking in the app, or read what clinician-led weight management actually involves before deciding.
What this is not.
- This is a structured worksheet, not a diagnosis. It cannot tell you whether you have a condition or predict that you will develop one.
- No obesity risk score or category is published. The source document states two different maximum scores and its categories overlap.
- BMI does not distinguish muscle from fat and is a poor guide for some bodies.
- If you have symptoms that worry you, contact a healthcare professional rather than waiting for an app.
