What is Yuzu Health?
Yuzu Health is a food scanner app for iPhone. Point your camera at a product barcode and it shows what's really inside: a 0–100 health score, and every ingredient and E-number rated on an EFSA-based safety scale (safe, watch, or avoid) with a plain-English reason and a link to the source. It's built specifically around EU food labelling.
What it does
Scan a barcode, and within seconds you get three things: an overall score, a colour-coded list of every additive, and (tap any ingredient) an explanation of what it is, what it does, and what regulators say. You get more than a verdict. You get the reasoning behind it, so you can decide for yourself at the shelf.
How the scoring works
The 0–100 score combines nutritional quality, additive risk and organic status. Additives are rated against EFSA scientific opinions and the EU Food Additives Database. Yuzu also separates two different questions: “is this additive a problem?” (a judgement about a specific substance) from “does this product have a lot of sugar?” (a question of quantity). It won't red-flag sugar as if it were a hazardous additive. That would be meaningless. Full methodology →
What makes it different
Yuzu is EU-first. Where general scanners give you a number, Yuzu explains every E-number in plain English and links the EFSA opinion behind each rating, so the verdict is checkable, not a black box. It reads European product labels natively, and when a product isn't already known it falls back to public databases and AI-assisted analysis so local EU retail products still resolve.
Platform & access
Yuzu Health is on the iOS App Store. You can scan as a guest with no account; signing in is optional and only syncs your history across devices. It's available as a subscription.
