Yuka vs Gut Score: processed food vs a health score

Yuka vs Gut Score is a common comparison if you already scan barcodes and now care about ultra-processed food. Both live on a phone and start with a pack. They do not answer the same question. Yuka is a general health-score scanner. Gut Score is an iPhone app for finding processed foods and tracking how processed your day is.

What Yuka is good at

Yuka looks up a product and returns a health score. That score mixes nutrition quality, additives, and other product signals into one rating. If you want a quick “better / worse” pick between two yogurts or two cereals, and you like a single colour-coded score, Yuka does that job. It is widely used and easy to explain to someone who has never thought about NOVA.

A health score is still a blend. A product can look decent on nutrients and still be ultra-processed. Another can be simply made and lose points for fat or salt. If processing is the thing you came to check, a blended health score can bury it.

What Gut Score is built for

Gut Score stays on one axis: processing. Scan a pack. Get a NOVA-style processed score — Low, Medium, High, or Very high. See the kcal. Log the meal. Watch a daily processed score for everything you have eaten. That is the whole product, on purpose.

• Processed score in plain English, not a 0–100 health blend.
• Kcal for the item and a running total for the day.
• A daily processed score so one barcode is not the whole story.
• A meal log — breakfast, lunch, dinner, snack — on your iPhone.

Side by side

• Question — Yuka: “How healthy is this product?” Gut Score: “How processed is this food, and how processed is my day?”
• Score — Yuka: a composite health rating. Gut Score: Low / Medium / High / Very high processing, plus kcal.
• Day view — Yuka is built around the product in your hand. Gut Score adds a daily processed score as you log meals.
• Platform — Gut Score is an iPhone app. Check Yuka’s current platforms if you need Android too.

Neither app replaces a clinician. Both can help you pause before a habit forms. The fair split is: use a health-score scanner when you want a blended rating; use Gut Score when ultra-processed food is the actual question.

When to pick which

Pick Yuka if you want one familiar health score and you are comparing products on overall quality. Pick Gut Score if you want to find processed foods, read a processing label, see kcal, and track the day. People who already use Yuka often add Gut Score when they notice “good” scores on foods that still feel industrial.
