How to use
KindlyChecked.

1. Open the app
   Tap the KindlyChecked icon on your home screen, or open the URL in your browser. The home screen shows a big lime card that says "The label, kindly checked."
2. Tap the camera button
   It's the lime circle at the bottom-center of every screen, or the "Scan a product" button in the lime card. First time, your phone will ask for camera permission — say yes.
3. Aim at the barcode
   Line up the barcode within the four lime corners. A scanning beam pulses across the frame — you don't need to tap anything. We detect as soon as it's clear, usually in under a second.
4. Watch the green flash
   When we detect the barcode, the frame flashes brighter green and a check mark pops up. About 150ms later, you're on the result page.

The score is the headline answer — but it's not the whole story. Right below the product card you'll see a plain-language takeaway: one or two sentences in plain English explaining what kind of product this is and what's actually pulling the score. Calibrated to the score band — a Strong product gets a "no real notes here," a Heavy one gets an honest "best treated as an occasional indulgence." Below that, the breakdown: a list of reasons that explain why it scored what it did. Some are good (lime checkmarks), some are flags (red triangles).

Tap any flag to expand it into a full explanation — what the ingredient is in plain English, the specific concern (with named regulatory bodies), and an evidence level so you know how confident the science is. Tap the Ingredients section to see the full ingredient list straight from the package — same data the algorithm uses, no filtering, no spin.

At the bottom of every result, the "Where we got this info" section lists our actual sources — Nutri-Score, IARC, EFSA, FDA, EWG, EPA — with direct links so you can verify anything we tell you.

Open the Profile tab (the person icon in the bottom nav). Scroll down to "My allergies". You'll see nine common allergens as toggleable pills: gluten, dairy, eggs, nuts, peanuts, soy, fish, shellfish, sesame.

Tap the ones that apply. Each active allergen turns red and shows a checkmark. That's it — you're set forever (or until you change them).

Now every product you scan gets checked against your allergens. If a product contains any of them:

• A red banner appears at the top
  Before you even see the score. "Contains your allergen — 🥛 Dairy" with a warning icon. Impossible to miss.
• The score is automatically capped at 20
  No matter how good the rest of the ingredients are, allergen products land in the "Avoid" tier. The math protects you.
• Better-pick suggestions filter them out too
  When we recommend alternatives, we filter out anything containing your allergens. You'll never get suggested a product you can't eat.

Scan something that scores under 50, and scroll down past the breakdown. You'll see a section called "Better picks for you" with up to four alternatives, ranked by score.

Each alternative card shows the product name, brand, image, and its score in a colored pill. Tap any one to scan it directly — useful when you want to see why the alternative scored higher.

The picks are filtered three ways:

• Same category as what you scanned
  If you scanned a chocolate spread, we find better chocolate spreads — not unrelated foods. We use the product's category from Open Food Facts.
• Score 70 or higher
  No marginal swaps. We only suggest alternatives that score at least 10 points higher than what you scanned. If nothing meaningfully better exists, we won't show this section at all rather than waste your time.
• Allergen-safe
  Anything containing your allergens is filtered out before we even sort. You never get suggested something you can't have.
