Look Twice
iPhone · Allergen labels

A second pair of eyes on every label.

Point your camera at the ingredient list. Look Twice reads the small print and shows you every allergen word it found.

Measured, not promised

Tested on 331 real labels, on a Mac and on an iPhone.

Every miss is named, with a date, and the numbers are updated every time the app changes.

One list per person

Everyone's list is different.

Add each person and their allergens, once. Before a scan, pick who it's for. The verdict checks their list and nothing else.

Checking for everyone at once works too.

Reads the actual label

Not a database. The words in front of you.

Barcode apps trust a catalog. Recipes change, and catalogs lag behind. Look Twice reads what's printed on the package in your hand: the full ingredient list and the contains statement.

When a word won't read, it says so instead of guessing.

Shows its work

One verdict, and the words behind it.

Every verdict shows its evidence. One line tells you who it was for and why. Below that, Allergen Facts lists each allergen next to the exact word on the label behind it, and shows you where that word sits.
