How it works

Check a product, read a clear result, and see exactly why. Coming soon to the App Store and Google Play.

The app asking which health topics you would like guidance on.

Step 1

Choose what matters to you

Pick any of the seven health topics. They stay on your phone, and you can change them whenever you like.

The home screen, with options to scan a barcode, type the digits or photograph a label.

Step 2

Check a product

Scan the barcode, type the digits, or photograph the label when a product is not in any database. The first time, the app asks before it sends a photo.

A result reading Avoid during pregnancy, naming retinol as the ingredient driving it, with a verdict for each topic. The product is an invented example.

Step 3

Read the result

You get a verdict for each topic, and the highest-risk topic sets the overall result. When too little of a label can be read, it says Unknown. See how it is worked out.

An ingredient sheet for retinol: what it is, why it is flagged, the strength of evidence, and its sources.

Step 4

Tap any ingredient. See who says so.

What it is, why it may matter for the topics you picked, how strong the evidence is, and which sources say so. You can browse them here too.

A history of scanned products, each with its verdict. The products are invented examples.

Step 5

Your history stays on your phone

Your scan history and saved products are kept on your device. See what leaves it, and why.
