How Scan & Score Works: Turn Any Barcode Into a Health Decision
Quick summary: Scan & Score is EvaShark's in-app barcode scanner that turns a split-second scan into a clear, useful read on the food in your hand. Point your camera at a product's barcode and EvaShark surfaces the full ingredient list, an overall health score, and a Halal certified tag when the item qualifies—so you can make a confident call in the middle of a grocery aisle instead of squinting at a tiny label. It is built for speed and clarity: no manual ingredient entry, no guesswork about which additives are worth avoiding. The health score distills several signals—added sugar, artificial additives, preservatives, and how processed an item is—into one glanceable number, while the Halal tag does the tedious work of checking for hidden non-Halal ingredients like gelatin, certain enzymes, or alcohol-based additives. Scan & Score is a shopping aid, not a medical device: it does not diagnose or treat anything, and it never replaces the advice of a clinician or dietitian. It simply gives you better information, faster, so the choice is yours.
Reading food labels is a skill most of us never learned. The print is small, the ingredient lists are long, and the marketing on the front of the package is designed to reassure you into a purchase before you ever flip it over.
Scan & Score exists to close that gap: one scan, and the thing you actually need to know is in front of you.
What a scan actually shows you
When you scan a barcode, EvaShark looks up the product and returns three things:
- The ingredient list — in plain language, so you can see what is actually inside.
- A health score — a glanceable number that weighs factors like added sugar, artificial colors and preservatives, and overall processing level.
- A Halal certified tag — shown when the product's ingredients meet Halal standards, sparing you the detective work of spotting hidden non-Halal additives.
The goal is not to shame any food. It is to give you information in the two seconds you have while deciding what goes in your cart.
Why the moment matters
Most grocery decisions happen in under ten seconds, surrounded by a store engineered to make you buy more. By the time you are home and Googling an ingredient, the purchase is already made.
Scan & Score moves the information to the point of decision. That single shift—clarity before the cart, not after—is where the real value lives.
How the health score works
A useful score is not a magic number; it is a summary of patterns. The score generally reflects:
- Added sugars hiding under many names (syrup, nectar, maltose, and dozens more)
- Artificial additives — colors, flavors, and preservatives with long chemical names
- Level of processing — how far a product is from a whole food
- Ingredient length and clarity — the fewer mystery ingredients, the better
A short ingredient list with recognizable foods scores well. A long list of additives scores lower. The score is a conversation starter, not a verdict.
The Halal certified tag
For shoppers who follow Halal dietary guidelines, the hard part is rarely the obvious stuff—it is the hidden ingredients. Gelatin in marshmallows, rennet in certain cheeses, alcohol-based flavor extracts, and enzymes of unclear origin can all hide inside an otherwise "normal" product.
The Halal tag does that checking for you, so you do not have to memorize every additive name or second-guess every label. If you want the full picture of how food choices connect to your health, see grocery shopping for hormonal health.
What Scan & Score is not
A few honest boundaries:
- It is not a medical device and does not diagnose, treat, or prevent any condition.
- It is not a substitute for a dietitian when you have a specific condition, allergy, or medical need.
- It is not here to judge your choices—only to make them informed.
If you have a diagnosed condition like PCOS, a thyroid disorder, or food allergies, a dietitian or clinician can help you use the score in a way that fits your needs. Our guide to early signs of PCOS explains why individualized advice matters.
