What Yuka checks, and what it doesn't
Yuka and TilliT aren't really answering the same question. Millions of people already trust Yuka to scan a barcode before buying, and this page is for them.
Yuka
Scores whether a product looks nutritionally healthy, based on its ingredient and additive list, instantly, from a barcode scan. Organic certification is a small, fixed bonus on top of that score, not an independent check that the certification itself is real.
TilliT
Checks whether a claim like Organic, Vegan, Gluten-Free or Allergen-Free is actually backed by public proof: a certificate, a registry match, a named certifier's own listing. A product can score well on Yuka and still have an unproven badge claim, and the other way round.
In Yuka's own words
Yuka's help center explains its verification process: an automatic system checks that a product's ingredient label was photographed and transcribed correctly, and a human team reviews new entries for the same kind of accuracy. Organic status contributes a fixed bonus to the score whenever a product carries "an official national or international organic label." There's no described step that checks the certification against the certifying body itself.
So: Yuka checks that what's printed on the package was copied down right. It doesn't check whether what's printed is true. That's the exact gap TilliT exists to fill, and that's from Yuka's own words, not our read of them.
A real example: gluten-free isn't one standard
"Gluten-free" certification isn't one consistent bar. GFCO certifies at 10 parts per million, NSF at 20 ppm, GFFP at 5 ppm. Three genuinely different thresholds, sold under labels that look identical to a shopper. Research also shows up to 30% of people with celiac disease on a gluten-free diet still have intestinal inflammation. So "which certificate, at what threshold" isn't just a technicality, it's health-relevant.
See how TilliT checks gluten-free claimsThis isn't about which app is "better." Yuka does something real, and does it well, millions of people already trust it before they buy. What it isn't built to do is check whether a certification claim is actually true, and that's a different, equally real question. Yuka's own policy is that it never takes partnerships or sponsorships of any kind, the same independence principle this page, and TilliT, are built on. As far as we could find, nobody had written a plain answer to "does Yuka check organic certification" before. Now there is one.
