Nothing happened when I scanned a barcode
MesoMetric opens the manual food form instead
When MesoMetric cannot find a product, it opens the manual food form with the barcode filled in.
There is no "product not found" message.
Enter the macros from the label and save.
It happens once per product
After the food is saved, MesoMetric stores it against the barcode. Scanning the same product opens it with your numbers, with no lookup.
Why a product might not be found
Barcode results come from Open Food Facts, a free food list that anyone can contribute to.
A scan opens the manual form when:
- the product is not in the list
- the entry exists but has no usable macros
- your phone is offline
- the lookup took too long
In all four cases, enter the numbers manually.
The numbers are wrong
Open Food Facts entries are not checked before publication.
Check the numbers against the product label. Tap Edit / Correct and enter the correct numbers. MesoMetric uses yours from then on.
The camera never opened
This is a separate problem. MesoMetric requires permission to use your camera.
Enable camera access in Settings to scan a barcode, or enter the food manually.
The food can be created manually instead.
