> label is a free food transparency mobile app (iOS and Android, coming soon) that helps people
> make healthier, more informed food choices by scanning barcodes and surfacing science-backed data.

## What label does

Scan any food product's barcode and instantly receive:

- An **A–F health grade** computed from 12 nutritional variables
- Every ingredient explained in plain English, with a harm score sourced from EFSA, FDA, and WHO
- The full **corporate ownership chain** — from the brand on the box to the ultimate parent company
- A **healthier swap** suggestion with a better grade
- **Weekly diet stats** tracking your average grade, top categories, and personal goals

## How the A–F grade is calculated

The score starts at 100. Deductions:
- Sugar > 22.5g/100g: −30 | > 11.25g: −15 | > 5g: −5
- Saturated fat > 5g: −20 | > 2.5g: −10
- Sodium > 600mg: −20 | > 300mg: −10 | > 150mg: −5
- NOVA group 4 (ultra-processed): −20 | NOVA group 3: −10
- Each additive with harm score > 60: −5 per additive
- Glycaemic index > 70: −15 | > 55: −5

Additions:
- Fibre ≥ 6g: +10 | ≥ 3g: +5
- Protein ≥ 10g: +5

Grade bands: A (80–100) · B (65–79) · C (50–64) · D (35–49) · F (0–34)

## Ingredient harm scoring

Each ingredient and food additive receives a harm score from 0–100:
- 0–30: Safe / low concern (green)
- 31–60: Moderate concern (amber)
- 61–100: High concern / avoid (red)

Scores are sourced from peer-reviewed literature published by EFSA (European Food Safety Authority),
FDA (US Food and Drug Administration), and WHO (World Health Organization). Every claim displays
its source citation. label never states an ingredient "causes" harm — language is always
"associated with" or "linked in studies to".

## What label is NOT

- label is not a medical device and does not give medical advice
- label does not claim community-sourced product data is verified unless explicitly confirmed
- label is not a substitute for reading packaging; unverified data always shows a warning

## Data sources

- Product data: Open Food Facts (community-contributed, 3M+ products)
- Nutrient data: USDA FoodData Central
- Ingredient harm scores: EFSA, FDA, WHO scientific literature
- Farmers markets (US): USDA Farmers Market Directory
- Farmers markets (international): OpenStreetMap Overpass API

## Features in detail

**Barcode scan**: Point camera at any packaged food product. Results return in under 2 seconds
from a database of 3 million+ products.

**Dietary filters**: Flag products that conflict with vegan, vegetarian, gluten-free, dairy-free,
nut-free, halal, kosher, or other dietary requirements. Filters are keyword-based at MVP.

## Mission

label believes every person deserves to know what is in their food, who made it, and what
the science says about its ingredients — without needing a nutrition degree. Food transparency
should be a right, not a privilege.
