Know what's in your food.
Cull the ultra-processed.
Not medical advice — see disclaimers.
Health Score
One number. The whole truth.
Every product gets a score from 0 to 100 based on three things: how nutritious it is, whether the additives are safe, and how processed it is. The formula is transparent — you can see every calculation inside the app.
Nutritional Quality
Good stuff vs. bad stuff. Protein, fibre, and vitamins weighed against sugar, sodium, and saturated fat.
Additive Safety
Every additive checked against scientific safety databases. Harmful chemicals and allergens drag the score down.
Processing Level
How far is this from real food? Ultra-processed products receive significantly lower scores.
A sugary cereal typically lands around 41 (NOVA 4, high added sugar). Plain porridge oats land near 74 (minimally processed, high fibre).
