Every food scanner app does the same first step. You point your phone at a barcode and it pulls up the product. What happens next is where they split. Some apps grade nutrition, some hunt for additives, some check your allergies, and a couple do a bit of everything.
So there isn’t one best food scanner app. There’s a best app for the question you’re asking in the aisle. Below are the six we see parents use most. For each one we cover how it scores food, what it costs, and how well it catches the thing we care about most here: added sugar in kids’ snacks.
We didn’t run lab tests on these apps. Everything below comes from each app’s published scoring method and store listing, checked on October 1, 2026. Prices and features change, so confirm in the app store before you pay.
The short version
| App | Score format | What drives the score | Price | Best for |
|---|---|---|---|---|
| Yuka | 0 to 100 | Nutrition 60%, additives 30%, organic 10% | Free, paid tier listed at $15/year | One quick number plus additive warnings |
| EWG Healthy Living | 1 (best) to 10 (worst) | Nutrition, ingredient concerns, processing | Free | Pesticide, contaminant, and additive concerns |
| Open Food Facts | Nutri-Score A to E, NOVA 1 to 4 | Nutri-Score formula, processing level | Free, nonprofit | Raw data and international products |
| Fooducate | Letter grade A to D | Nutrition plus ingredient notes | Free, paid tier | Calorie tracking with grades |
| Bobby Approved | Approved or not | A list of 100+ flagged ingredients | Free (iPhone only) | Strict ingredient screening |
| Fig | Match or no match | Your own diet and allergy profile | Free, Fig+ subscription | Allergies and restrictive diets |
Yuka
Yuka is the best known scanner, and its method is public. Per Yuka’s help center, nutritional quality makes up 60% of the score and is based on Nutri-Score. Additives make up 30%, and any additive Yuka rates as high risk caps the product at 49 out of 100. Being organic counts for the last 10%.
That additive cap is the main reason parents like it. A snack with a dye or preservative Yuka considers high risk can’t land in the green, no matter how good its nutrition looks.
Where it falls short for kids: Nutri-Score uses total sugar, not added sugar. Plain milk and a chocolate milk with the same total sugar look closer than they should. Scores are also per 100 grams, not per serving, so a small 20 gram fruit snack pack and a full cup of yogurt get judged on the same scale.
EWG Healthy Living (Food Scores)
The Environmental Working Group’s app scans food alongside personal care and cleaning products. Its Food Scores run from 1 (best) to 10 (worst). EWG’s methodology anchors the score on nutrition, then adds weighted penalties for ingredient concerns and degree of processing. Processed foods that aren’t certified organic get an extra half point.
The ingredient concern score is the standout. It looks past the label to likely contaminants, pesticides, hormones, antibiotics, and additives of concern.
Where it falls short for kids: the database relies on licensed label data, so newer products can be missing. Like Yuka, it gives one blended score. A snack can score fine overall and still carry more added sugar than you want in a lunchbox.
Open Food Facts
Open Food Facts is a nonprofit, volunteer-built database that calls itself the Wikipedia of food. Its app covers more than 4 million products and shows the Nutri-Score grade (A to E) and the NOVA group (1 to 4), which measures how processed a food is. The data is open, and many other apps, Yuka included, have been built on top of it.
If a product is missing, you can photograph it and add it yourself.
Where it falls short for kids: because anyone can edit entries, data quality varies. US products in particular sometimes have wrong serving sizes or missing nutrients. It’s a great research tool and a less reliable quick verdict.
Fooducate
Fooducate has been around since 2009. It grades products from A to D and pairs the grade with short notes explaining what helped or hurt the score. It also works as a calorie and diet tracker, which is the main reason people pay for its premium tier.
Where it falls short for kids: the app is built around adult weight and diet tracking. The grade is useful, but there’s no setting for a child’s age or daily sugar limit.
Bobby Approved
Bobby Approved comes from Bobby Parrish of FlavCity. It’s free and iPhone only. Instead of a number, it tells you whether a product passes or fails against a list of more than 100 ingredients Bobby flags. Flagged ingredients show in red, and tapping one explains why. If a product fails, the app suggests alternatives.
Where it falls short for kids: pass or fail is easy to act on, but the list reflects one person’s standards. Some flagged ingredients have stronger evidence against them than others. Sugar content doesn’t change the verdict the way an ingredient flag does.
Fig
Fig, short for Food is Good, takes a different approach. You build a profile of everything you avoid, such as a peanut allergy, gluten, low FODMAP, or added sugar. The app then tells you whether a product matches. It’s free, with a Fig+ subscription that adds multiple profiles, restaurant lookups, and unlimited scans.
Where it falls short for kids: Fig answers “can my kid eat this?” very well. It doesn’t answer “is this a good snack?” There’s no health score, just a match. For families managing allergies, though, it may be the most useful app on this list.
What none of these apps do well: added sugar for kids
The American Heart Association recommends kids ages 2 to 18 keep added sugar under 25 grams a day, and none at all before age 2. Since 2020 the FDA has required most packaged foods to list added sugar on its own line of the Nutrition Facts label, separate from total sugar.
Most scanner apps were built before that line existed or for adults. They blend sugar into a broader nutrition score, usually per 100 grams and usually using total sugar. That’s fine for a general verdict. It’s less helpful when you’re deciding between two granola bars for a seven year old.
That gap is why we built Sugar Check. Every product on the site gets a grade from A to E, based only on added sugar per labeled serving, never per 100 grams. Tier A has essentially no sugar, Tier B has 0g added, and Tier E has more than 5g added per serving. Dye, nut, dairy, and high fructose corn syrup flags sit next to the grade. Search any snack on the browse page or start with a list like the best healthy snacks for kids.
Sugar Check is a website today, not a phone app. A barcode scanner is in the works, and you can join the waitlist from our home page.
Which food scanner app should you use?
- You want one simple number: Yuka.
- You worry about pesticides, contaminants, or additives: EWG Healthy Living.
- You want free, open data and don’t mind checking it: Open Food Facts.
- You’re also tracking your own calories: Fooducate.
- You want a strict ingredient filter: Bobby Approved.
- Your child has allergies or a medical diet: Fig.
- Added sugar is the main thing you’re trying to cut: check the label’s “Includes Xg Added Sugars” line, or look the snack up on Sugar Check.
Plenty of parents use two of these: one for allergies or ingredients, and one for nutrition. Whatever app you pick, the label in your hand is still the final word. Apps can lag behind reformulated products, so if a score looks off, flip the package over and check.
