Know before
you bite.
Point your phone at a barcode. Gluten and lactose get separate answers, in seconds.
Two free scans a week. No account, no download.
Reading a label shouldn't be guesswork
Tiny print. A language you don't fully read. An ingredient name you're not sure is a synonym for wheat or not. For celiac disease and lactose intolerance, guessing wrong isn't a bad meal — it's real discomfort. Knowbite isn't a medical device — it's built by someone who lives with this, for people who need a straight answer, fast.

Gluten and lactose, from barcode and ingredient data. It’s informational — it doesn’t replace reading the label yourself or checking with a doctor.
You’ll see a clear "not found" screen and can report it in one tap, so it gets added for next time.
Sometimes there isn’t enough data to check an allergen with confidence. Rather than guess, Knowbite says so honestly instead of showing a false safe or unsafe.
