Yuka App Review UK (2026)
The food scanning app that rates products from "Excellent" to "Bad" - but how accurate is it really?
What is Yuka?
Yuka is a French food and cosmetics scanning app with over 80 million users worldwide. You scan a product's barcode and get an instant score from 0-100, plus a traffic light rating: Excellent (dark green), Good (light green), Mediocre (orange), or Bad (red).
Unlike calorie counting apps, Yuka doesn't track your daily intake. It's a product scanner designed to help you make "healthier" choices while shopping by highlighting additives, nutritional quality, and whether products are organic.
How Yuka Scores Products
Each product score is calculated from three factors:
- Nutritional quality (60%): Based on the Nutri-Score system - calories, sugar, saturated fat, salt, protein, fibre
- Additives (30%): Presence of artificial additives, preservatives, colourings
- Organic (10%): Bonus points if the product is certified organic
Is Yuka Accurate?
This is where Yuka gets controversial. The app is reasonably good at identifying additives, but the overall "health" scores can be misleading.
The problems:
- Nutritious foods penalised: Whole foods like cheese, nuts, and eggs can score poorly because the algorithm penalises fat regardless of nutritional value
- One-size-fits-all scoring: The algorithm gives a universal score - it doesn't adjust for individual dietary needs or contexts
- Organic bias: Products get 10% bonus just for being organic, even though organic doesn't mean healthier
- Additives oversimplified: Some "scary-sounding" additives are completely safe; some natural ingredients aren't
What Yuka Does Well
Despite the scoring issues, Yuka has genuine uses:
- Additive transparency: Quickly see what's actually in a product
- Ingredient education: Learn what E-numbers and additives actually are
- Comparison shopping: Compare similar products to find cleaner options
- Cosmetics scanning: Also rates skincare and beauty products
- Quick reference: Faster than reading tiny ingredient labels
Yuka Pricing UK
Yuka's basic scanning is free. Premium adds extra features:
- Free: Unlimited barcode scanning, product ratings
- Premium (£10-15/year): Search bar, offline mode, unlimited history, dietary filters (vegan, gluten-free, etc.)

What Real Users Say
Yuka has a polarised 3.2/5 on UK Trustpilot - 47% give 5 stars, but 32% give 1 star. Users either love it or hate it:
"Immensely useful for finding out the contents of packaged foods. Makes clear which additives are harmful to health." - Trustpilot review
"The same product gets different scores at different times. They don't fact-check the information - they rely solely on manufacturer labels." - Trustpilot review
Common praise: Additive awareness, easy to use, good for quick checks
Common complaints: Inconsistent scores, questionable accuracy, promotes food anxiety
Who Yuka Is Best For
Additive-Conscious
If you want to avoid specific additives or E-numbers, Yuka helps identify them quickly.
Comparison Shoppers
Useful for comparing similar products (e.g., which bread has fewer additives).
Label Learners
Good educational tool for understanding what's actually in processed foods.
Cosmetics Users
Also scans skincare and beauty products for concerning ingredients.
Who Should Look Elsewhere
- Calorie trackers: Yuka doesn't track daily intake - you'll need a dedicated calorie tracking app
- Macro counters: No protein/carb/fat tracking
- Anxious eaters: The red "Bad" ratings can trigger food anxiety
- Context-dependent diets: Athletes, medical diets, etc. need more nuance than traffic lights
The Bottom Line
Yuka is a handy tool for quickly checking what's in a product - especially additives and preservatives. But don't treat the scores as health gospel. The algorithm penalises nutritious foods like cheese and nuts while giving bonus points for organic marketing.
Use it as one input alongside your own judgement. And if you want to actually track calories and macros, you'll need a different app entirely.
Our verdict: Useful for additive awareness, but take the "health" scores with a pinch of salt.
