The best food scanner app, honestly
Nobody can hand you a single answer here, and anyone who does is selling something. The honest version is that the right scanner depends on where you shop and what you want to know. Here is how the main options actually differ.
Yuka
The best-known option in Europe, and for good reason. It has a huge database and covers cosmetics as well as food, with a score built from nutrition, additives and organic status. If you want one app for a bit of everything and the widest product coverage, it is a strong pick. The trade-off is depth: you get a score more than a detailed, sourced explanation of each additive.
Open Food Facts
A free, community-built database and app. Its openness is genuinely valuable, and it powers parts of other tools. Coverage is broad but uneven, and how much detail you get on a given product depends on what contributors have added for it.
Yuzu Health
Built for EU labelling, with additives as the focus. It reads a barcode, then explains every ingredient and E-number in plain English and rates each one against EFSA opinions, with the source attached. Its score deliberately keeps additive risk separate from bulk-nutrient quantity, so sugar does not get flagged as if it were a hazardous chemical. If you care about understanding why a product scored the way it did, this is the detailed end of the spectrum. How Yuzu works.
How to choose
If you want the widest net and cosmetics too, Yuka. If you want free and open, Open Food Facts. If you shop in the EU and want to actually understand the additives, with a source you can check, Yuzu. There is a fuller breakdown of what to look for in our guide to food scanners in Europe.
