YummyLogy Scanner App

Coming soon to iPhone

Know what's really in your food, in one tap.

The YummyLogy Scanner app reads a barcode (or a photo of the ingredient label) and tells you whether the product is approved, not approved, or needs caution — based on the same rules engine that powers the badges on this site.

iOS · Free during beta · No account required

How it works

1 · Scan the barcode

Point your iPhone camera at any UPC. The app looks up the product in our private cache, then USDA FDC, then Open Food Facts (3M+ items).

2 · Or photograph the label

No barcode? Snap the ingredient list. On-device OCR + cloud parsing extracts the ingredients and runs them through the rules engine.

3 · See the verdict instantly

Get a clear "YummyLogy Approved" or "Not Approved" verdict, plus a quality tier — Premium, Good, Standard, or Industrial — and a checklist of what we flagged.

The verdict, at a glance

Every product gets one of four quality tiers, layered on top of the binary approve/reject:

✓ Premium ✓ Good ⚠ Caution ✗ Not Approved

What we check for

  • Artificial flavors & colors (incl. EU-restricted dyes)
  • Refined seed & vegetable oils
  • Artificial sweeteners (aspartame, sucralose, etc.)
  • Common preservatives (BHA, BHT, sodium benzoate)
  • Modified food starches
  • Glucose syrup, high-fructose corn syrup
  • FD&C lake dyes
  • Heavy-metal contamination indicators
  • Organic certification status
  • Quality signals (cold pressed, single origin, raw, unfiltered, etc.)
Built on real regulatory data. The rules engine cross-references each ingredient against 17+ regulatory jurisdictions — FDA, EFSA, Health Canada, FSANZ, IARC, and more — so you can see things like "Red 40 requires a warning label in the EU" or "Titanium dioxide is banned in EU/France, permitted in US/UK/Canada". Data sources: Open Food Facts, USDA FoodData Central, plus our own ingredient + quality-attribute rules curated by the YummyLogy editorial team.

Privacy

You don't need an account to scan. Barcodes and label photos you submit help expand our public product database — they aren't tied to your identity. The app stores its API key in iOS Keychain.
