Scan a barcode
Point your camera at a packet to pull up what we hold for it — or scan two and put them head to head, which is the question you actually have standing in the aisle.
What this does and doesn’t do
A barcode is a lookup, not a guess. The answer is the product carrying that number or nothing at all — we never show you a “probably this”.
It also can’t tell how much you ate. The code identifies the product; the portion is yours to set on My Plate.
The camera image is processed on your device and never uploaded. Only the number is sent, to look it up.
