How Boone works

From your plate to a clear picture of your diet

Log what you actually eat in seconds. Boone works out what's in it, tracks the patterns over time and, if you add a DNA test, shows how your diet fits your biology.

Free to start. No DNA test needed.

Boone breaks it down

Every meal becomes structured nutrition data: calories and macros, 29 vitamins and minerals, and how processed it is.

Patterns build over time

Instead of judging single meals, Boone looks across days and weeks: how your energy is split, which nutrients turn up consistently, how varied your diet is and how much is ultra-processed.

How the DNA test works

A simple saliva test, done at home. It looks at selected genetic variants linked to how your body handles certain nutrients, and adds them to the app as context for your diet.

Diet and DNA together

Where it all comes together

With both in place, Boone shows your eating patterns alongside traits from your DNA. You can see where your diet already suits your biology, and where a small change could make more difference.

Context, not prediction. Genetic effects on nutrition are usually modest, and habits matter most. Read the science →
