“Hi, could I ask a favour? The ragu came back positive on my gluten test. I have celiac disease. Could you send it back and check the sauce base? I'd love something else if it isn't safe.”

Appearance

Your data and case

Bite Check 0.4 · concept prototype. The case is not a real product and this is not a medical device: it can't tell you whether food is safe.

Concept · Bite Check

Know what's on your fork before the next bite.

Bite Check pairs a phone app with a pocket utensil case. Each time you rest your fork or spoon in the case, it swabs the residue and checks it for gluten, so the sample is exactly what reached your mouth.

Concept hardware. The case doesn't exist yet and this isn't a medical device. Every reading, restaurant and meal in this demo is made up.

Pairing the case

First run: the app finds the case over Bluetooth and checks that both utensils are seated.

Try Tap Start pairing, then choose your limit.

Design principles

Uncertain is a real answer. Readings show a confidence level and a ppm range against your own limit, not a smiley face or a wheat icon.
Every alert ends with a next step. Send Back gives you words for the server, a large-type card to show them, and safer dishes on the same menu.
The sample is what you ate. Testing utensil residue avoids cutting off a crumb that may not match the rest of the plate.
Cleanup happens at home. Used swabs stay sealed in the case and drop out once a week as one foil pouch, so nothing ends up on the table.
