ASO Audit:Yuka

Does their ASO suck?

My take: Getting there. Keep going.

Yuka’s opening makes its scan-and-rate model very clear: a food score, a cosmetic ingredient list and alternative products. The colours and labels are decisive. The important next step is helping a visitor understand what those ratings mean and how to inspect their basis. I would test explanation-led wording while keeping product ratings distinct from individual health advice.

Check What's in Your Products

Open the source listing ↗. Public text cannot reveal the private keyword field, search volumes, rankings or conversion rates. The recommendations below are proposals to validate.

Three things worth your attention

01

The food result looks conclusive.

What I saw. The first frame shows a named cereal, a low numerical score and a breakdown of additives and nutrients.

My read. A crisp score is easy to scan but can be mistaken for a complete judgement of a person’s diet or suitability.

What I’d do. Verify the current scoring explanation and test wording that invites inspection of the breakdown.

02

The cosmetic view classifies ingredients.

What I saw. The second frame lists ingredients with risk labels and information icons beneath a harmful-ingredients headline.

My read. The information controls are useful, but the headline foregrounds avoidance before the visitor sees how the classifications are derived.

What I’d do. Verify the method and source path, and make clear that the audit is reporting app classifications rather than independently assessing ingredients.

03

The alternative view recommends a direction.

What I saw. The third frame pairs products with crosses, ticks and contrasting rating labels.

My read. The visual makes substitution feel simple, while formulation, preferences, availability and personal suitability remain outside the still.

What I’d do. Check current comparison criteria and avoid treating a higher app score as a universal recommendation for every person.

The screenshot teardown

The original creative is preserved. Numbered notes sit beside each frame so observations and recommendations stay separate.

Frame 01Yuka first screenshot with a cereal product, numerical rating and additive and nutrient breakdown.

The captured creative presents the app’s score alongside per-serving values and coloured labels.

It demonstrates a result format, not independent evidence that the displayed product data or health interpretation is current or individually appropriate.

Test idea: Verify the current record and scoring explanation before reuse and show where the user can inspect the basis.

Original image source ↗
Frame 02Yuka second screenshot with a moisturising cream rating, ingredient classifications and information buttons.

The headline promotes avoiding harmful ingredients, while the interface assigns several risk levels.

These are publisher classifications. The image alone cannot validate the evidence, exposure assumptions or suitability for a particular person.

Test idea: Check the current explanation and sources and compare wording centred on reviewing ingredients.

Original image source ↗
Frame 03Yuka third screenshot with food and personal-care product pairs, crosses, ticks and contrasting app ratings.

The sequence ends by presenting higher-rated alternatives according to the app.

A visual swap can imply broader certainty than a score comparison supports. No independent recommendation of these products is made here.

Test idea: Verify product records and comparison scope, and distinguish app rating from personalised suitability.

Three alternatives—and what they make clearer

Observed competitor metadata

Open Food Facts - Product Scan ↗

Food, Cosmetics & much more

Open Food Facts names product scanning across food, cosmetics and more.

The lesson: The scan-and-information job overlaps. Compare what the listing explains about product data without assuming identical scoring methods or database quality.

Observed competitor metadata

Bobby Approved - Food Scanner ↗

Scan labels, find healthy food

Bobby Approved names food scanning and finding healthy food.

The lesson: This is direct food-scanner intent, but the health wording is a publisher claim, not an independently validated comparison with Yuka.

Observed competitor metadata

Olive: Food & Cosmetic Scanner ↗

Scan & Eat Healthy Ingredients

Olive names food and cosmetic scanning with healthy-ingredient language.

The lesson: The scope overlaps both product types. A useful distinction is how clearly Yuka explains its own rating basis; shared vocabulary does not establish equivalent evidence.

Figure 2. US listing names and subtitles captured 30 September 2026. These are positioning comparisons, not ranking or revenue comparisons.

The keyword questions I’d investigate

Intent candidates grounded in the listing—not fabricated search-volume or difficulty scores.

food barcode scanner / ingredient checker

Visitor’s job: Identify a product and inspect its listed information.

Evidence: The name names scanning and the first frame shows a food result with a breakdown.

Decision: Keep the concrete information task and verify barcode matching, formulation and correction processes.

cosmetic scanner / skincare ingredients

Visitor’s job: Look up a personal-care product and inspect ingredient information.

Evidence: The second screenshot shows a cosmetic result and ingredient information controls.

Decision: Use accurate product-information language without equating a score with diagnosis, allergy safety or a personalised skincare recommendation.

product ratings / compare alternatives

Visitor’s job: Understand why products receive different app ratings.

Evidence: The third frame explicitly compares alternatives with contrasting labels.

Decision: Research comprehension of the rating method and comparison scope; do not infer search demand or individual health benefit.

The unseen keyword field may already cover some of these terms. Build an evidence-backed keyword shortlist before making a metadata change.

What I’d put on the table

Proposed copy for discussion. These are not current listing fields or tested winners.

Proposed alternative

Yuka - Food & Cosmetic Scanner

Scan products. Explore details

Name 30/30 · Subtitle 30/30 characters
Figure 3. A metadata alternative to review against the current listing.

Keep the observed category-rich name and describe the information workflow. The proposed subtitle encourages the user to inspect details rather than treating the first score as the whole decision.

The tradeoff: It replaces the broader check-what-is-in-your-products promise and does not advertise alternatives. Its usefulness depends on the current detail flow and audience understanding, not on a presumed ranking advantage.

A three-frame creative brief

  1. Proposed frame 01

    Scan a product to see its record

    Show: A verified current barcode match with the exact product and formulation context.

    Start with identification before interpretation.

  2. Proposed frame 02

    See how the rating is explained

    Show: The actual supported breakdown and source or method information, reviewed for accuracy.

    Make the basis of the app’s judgement visible.

  3. Proposed frame 03

    Compare the available information

    Show: A supported comparison with accurate product records and clear rating scope.

    Enable an informed comparison without a blanket health or suitability guarantee.

What three reviewers can teach us

Three 2022–2025 accounts were selected for information access, search and correction expectations. They are not a health-outcome study or database-accuracy sample. The corrected record remains explicit; individual ingredient conclusions, allergy assumptions and historical subscription details are not adopted as current verified facts.

Sample: 3 selected accounts from 8 displayed reviews. Dates: 12 December 2022–28 September 2025. No sentiment percentage is calculated.

12 December 2022 · 5/5 stars

“list out the ingredients”

A December 2022 reviewer valued accessing ingredient explanations while shopping.

What I’d investigate: Use the information-access motivation, not the account’s personal health or safety conclusions, as research evidence.

Listing review source · Review ID 9388785495

28 September 2025 · 5/5 stars

“scan and search”

A September 2025 reviewer liked scanning, searching and finding alternatives, and described submitting missing-product information.

What I’d investigate: Verify current access and review procedures; the account does not establish current pricing, database completeness or comparison quality.

Listing review source · Review ID 13197514488

8 March 2025 · 4/5 stars

“they fixed it”

A March 2025 reviewer described a product-data concern that they reported and said was corrected, alongside concerns about gluten-related feature access.

What I’d investigate: Preserve the correction. Do not treat a product score as an allergy or cross-contact guarantee, or adopt the reviewer’s ingredient allegations as verified facts.

Listing review source · Review ID 12395111802

A displayed review can be old, unusually positive or internally inconsistent with its star rating. These accounts suggest questions; they do not establish current defects or typical customer experience. Use the Review Research Desk to keep evidence and interpretation separate.

What I’d do first

01

Explain the rating basis

The strongest creative signals are numerical and categorical verdicts.

Deliverable: A verified method-and-source walkthrough for the pictured examples.

Required editorial and product review
02

Make details easy to understand

Information controls are present but secondary to avoidance language.

Deliverable: An explanation-led second-frame wording variant.

Low creative effort
03

Verify product-data handling

Selected accounts describe missing records and corrections.

Deliverable: A current barcode, formulation and correction-process source sheet.

Product research

One test worth running

Does explanation-led ingredient wording improve understanding of the app’s ratings while preserving qualified conversion?

Audience
Eligible US English iPhone default-page visitors, with separate research among food-information and cosmetic-information prospects.
Control
The current second-frame headline only after appropriate review substantiates its scope; correct any unsupported claim across variants before establishing a baseline.
Treatment
Change only the second-frame headline to verified ingredient-information wording, keeping the result view, sequence, metadata and other assets fixed after checking accuracy.
Method
Verify the current method and explanation path, then use comprehension research and eligible App Store product page optimization. This tests wording, not nutritional science, ingredient safety or health outcomes.
Primary measure
Platform-reported download conversion for eligible randomized traffic.
Guardrails
Participants should distinguish an app rating from individual medical or allergy advice and know that product details need checking. No conversion result establishes safety or health benefit.
Decision rule
Predefine useful effect, sample requirement and analysis timing from baseline traffic. Keep control if inconclusive; reject a lift caused by stronger mistaken certainty about product suitability.
What could muddy the result
Database updates, product reformulations, method changes, media coverage and the food-versus-cosmetic audience mix may affect results.

Check Apple’s current product page optimization guidance and custom product page guidance before configuring a test. Write your experiment brief.

So, does their ASO suck?

Getting there. The category and first action are immediately understandable. The opportunity is to give the scoring method and its limits the same prominence as the red and green verdicts. This audit describes the publisher’s displayed ratings; it does not independently validate the pictured ingredient classifications, recommend the alternatives or establish health outcomes.

  1. Level 1

    Yeah. It really does!

    The basics need a serious rethink.

  2. Level 2

    I hope no agency is getting paid for this.

    Too many obvious things have been left unfinished.

  3. Level 3

    The app deserves better.

    There is a useful product here. The listing needs to show it.

  4. Level 4

    Fine. If ‘fine’ is the goal.

    The essentials are there, but there is little to get excited about.

  5. Level 5Yuka is here

    Getting there. Keep going.

    Good ideas, with a few important gaps still to close.

  6. Level 6

    Solid. Put the pitchfork down.

    A strong foundation. Look for specific improvements, not a complete restart.

  7. Level 7

    Whoever did this knows their stuff.

    Clear positioning, thoughtful choices and very few loose ends.

  8. Level 8

    Okay, now you’re showing off.

    An unusually clear, convincing storefront worth learning from.

An editorial verdict on the captured storefront, not a measured ASO score or an assessment of an agency’s private work.

Your ASO assignment

  1. Verify the pictured product records and document the current rating-explanation path.
  2. Separate displayed classifications from independently established health or suitability claims.
  3. Test whether prospects know where to inspect details and report a product-data mismatch.
