Help with Pury, the on-device purity scanner for food, cosmetics and supplements.
Questions, bug reports or feedback? We usually reply within 2 business days.
Open Pury, tap a category (Food, Cosmetics or Supplements) and point the camera at the ingredients list or barcode. The purity verdict appears in a couple of seconds.
Pury rates each product 0–100 and gives a verdict — Clean, Worth a look or Best avoided — based on additives, ultra-processing (NOVA), allergens, and category-specific rules (e.g. the EU cosmetics restricted list). It is educational information, not medical advice.
Go to the Profile tab and add the allergens and diets you want flagged. Matching products then get a personal alert — computed on your device.
Yes. Open Profile → Language and choose English, Français, Deutsch, Español, Italiano or Български. Pury also follows your iPhone's system language by default.
No. Pury has no account and works fully offline. A connection is only used if you scan a barcode (to look it up in the open Open Food Facts database) or enable the optional Claude AI feature with your own API key.
Pury is free to use. Pury Plus and Pury AI are optional subscriptions that unlock unlimited history, unlimited allergens & diets, full insights, data export and AI explanations. Subscriptions are billed through your Apple ID and can be managed or cancelled any time in Settings → [your name] → Subscriptions.
