Frequently Asked Questions

What is Peek Scanner?

Peek Scanner is a barcode scanner for food and cosmetics that gives you a transparent, science-backed health score for any product. Scan a barcode and instantly see a full ingredient breakdown, allergen alerts, additive warnings, EU safety ratings, and a 0–100 health score — all explained in plain language.

How does the health score work?

Scores are calculated differently for food and cosmetics:

  • Food (0–100): Weighted formula combining Nutri-Score (40%), NOVA processing level (20%), additive risk (20%), and nutrient balance (20%)
  • Cosmetics (start at 100): Penalty-based — ingredients banned under EU COSING Annex II result in an instant 0; restricted ingredients (Annex III) and allergens deduct points

Score brackets: 76–100 Excellent · 51–75 Good · 26–50 Mediocre · 0–25 Bad. The full formula is viewable inside the app.

What databases does Peek Scanner use?

  • Open Food Facts: Free, open database for food product lookups by barcode
  • Open Beauty Facts: Same, for cosmetics and personal care products
  • EU COSING: Bundled database of 35,000+ cosmetic ingredients with official EU safety classification
  • BLS 4.0: German nutritional reference database used for enriched food scoring

What is Nutri-Score?

Nutri-Score is the official EU front-of-pack nutritional label, graded A–E (A = best). It factors in energy, saturated fat, sugars, salt, fibre, protein, and fruit/vegetable content. Peek Scanner displays the grade and explains exactly what drove the score up or down for that specific product.

What is the NOVA processing level?

NOVA classifies foods into four groups based on how heavily processed they are — from unprocessed whole foods (NOVA 1) to ultra-processed industrial formulations (NOVA 4). Research consistently links high NOVA 4 consumption to worse health outcomes. Peek Scanner shows the NOVA level and explains what it means for the specific product you scanned.

What product types does Peek Scanner cover?

Peek Scanner covers both:

  • Food & drinks: Packaged foods, snacks, beverages, supplements — anything with an EAN-13, EAN-8, or UPC-A barcode
  • Cosmetics & personal care: Skincare, haircare, makeup, sunscreen, deodorants, and more

Is Peek Scanner a medical device?

No. Peek Scanner is an informational tool. Scores and ingredient data are based on open databases and public EU safety classifications — not medical diagnosis or treatment recommendations. Always consult a healthcare professional for medical decisions.

What if a product isn't found by barcode?

If a barcode doesn't match any entry in Open Food Facts or Open Beauty Facts, you can use the photo scan fallback. Take a photo of the product and the AI pipeline (Gemini + visual search) identifies it, reads the ingredient list, and scores it the same way.

Where is my scan history stored?

Scan history is stored locally on your device using an encrypted SQLite database. Your data never leaves your phone. Deleting the app removes all scan history.

Does Peek Scanner work offline?

Barcode lookups require an internet connection to query Open Food Facts and Open Beauty Facts. Once a product has been fetched, it's cached locally so you can reopen it offline. Scan history always works offline.

Is Peek Scanner available outside Europe?

Yes — the barcode lookup works globally for any product in Open Food Facts or Open Beauty Facts. The EU-specific features (COSING safety data, Nutri-Score, NOVA) are most relevant for products sold in Europe, but the app can be used anywhere.

Is Peek Scanner available on Android?

Peek Scanner is currently iOS-only. Android support may come in a future update.
