Scan history
From the app’s English Help & Guide · Reference release 1.0.12
Every scan can be saved to your scan history — handy for products you buy again and want to remember whether they agreed with you. A clock icon appears in the Foods toolbar once you have at least one saved scan.
Tolerance markers
Each row in history has a three-state pill: Untested → Tolerated → Not tolerated. Tap to cycle, or long-press to pick directly. This is your own “did this product work for me” answer, separate from the ingredient-level verdicts you earn from reintroduction challenges.
Search and reopen
Search across product name, notes, and the captured ingredient text. Tap any row to reopen the full verdict view in read-only mode. Swipe to delete.
What it isn’t
Scan history is a list of products you’ve looked at — it doesn’t become part of your food library. Ingredient-level verdicts (wheat, onion, tomato) still live in Foods and are earned through reintroduction. Tolerance markers on scans are strictly personal notes about specific packets.
