Instant scan
How Kler evaluates a product
Seven filters reviewed on every scan. Here's a real example: a product to watch, not rejected, not approved without reservation.
iOS · free
Scan. Understand.
Eat better.
Kler instantly analyzes your food products and checks their compatibility with your health profile — allergies, intolerances, diets, pregnancy.
01 — The scan
One scan.
Three seconds.
Point the camera at the barcode. Kler queries OpenFoodFacts and RappelConso live, no account, no data upload.
02 — The verdict
Compatible.
Or not.
No score out of 100 to interpret, no nutrition jargon. A clear verdict, based on your profile, readable in one second in the aisle.
03 — The profile
Your rules.
Once.
Allergens, intolerances, diet: set it up once, Kler applies the filter on every scan for every family member.
04 — The alternative
Incompatible?
Here's better.
Kler doesn't just say no. It suggests a compatible alternative, available in the same aisle.
How it works
Scan, compare, then decide with confidence.
Readable verdict
One scan, as many verdicts as profiles
The same product can suit one person and not another. Kler checks every saved profile at once.
Better option
Refused? We suggest better
When a product doesn't fit your profile, Kler looks for a compatible alternative in the same category.
Built for your household
One scan, several food realities.
Kler keeps the verdict readable for every profile without turning grocery shopping into a spreadsheet.
Kids
Simple filters to avoid risky ingredients while shopping.
Allergies
Clear warnings when a product contains or traces a critical allergen.
Vegetarians
Quickly spot compatible products without re-reading every label.
