A product score is a reading aid, not a verdict

Start with the information on the product

A score is useful when it makes a crowded label easier to read without pretending that every purchase has one correct answer. Blurrix uses a product's available label and catalogue information to create a structured summary. For food, FoodScore combines nine weighted dimensions on a 0 to 100 scale. Those dimensions cover glycemic impact, processing level, nutrition, fibre and fermentation signals, fat quality, additives, plant diversity, protein and satiety, and sustainability information where it is available. The total is a weighted result, not a separate fact printed by the manufacturer. The product page keeps the dimensions visible because a total alone cannot tell you why two products land close together.

The food score is designed around the product as sold. It reads nutrients per 100 grams where those fields are available, examines ingredient information, and uses processing signals such as NOVA data or ingredient heuristics when the source does not supply NOVA. A high value in one dimension does not erase a weaker value in another. Fibre can improve the fibre-related dimension without making a sweet product identical to an unsweetened one. A short ingredient list can be useful context without making nutrition information irrelevant. The weighting is published in the app's scoring documentation so the score is not an unexplained label.

FoodScore also has guardrails. Some product patterns trigger score caps or warnings, and incomplete data can limit how confidently a result is presented. These rules exist to keep a missing field from looking like a favourable field. They do not turn the score into a judgement about a person, a meal, or a way of eating. It is a description of a particular product record at a particular time. A product can be useful in a recipe, convenient on a busy day, or simply something you enjoy even when another product has a higher number.

Other product domains use their own analysis rather than being forced through the food model. Cosmetics have BeautySafe dimensions and supplement products have supplement-specific analysis. That separation matters. A number is comparable within the context the app provides, but it is not a universal ranking of food, cosmetics, and supplements against one another. Read the domain label and the supporting cards before drawing conclusions.

The most practical way to use a score is to open the detail behind it. Check the product name, serving context, ingredients, nutrition panel, and any data-quality message. If the package in your hand differs from the record, trust the package and consider scanning it again. Formulas, portion sizes, and marketing claims can change. Blurrix can help organize the information, but it cannot see a reformulation until new record data reaches the product record.

Scores are therefore best used as a comparison prompt. When choosing between similar products, look at the total and then at the dimensions that matter to the choice in front of you. When a result surprises you, inspect the inputs rather than treating the app as an control that ends the conversation. The useful outcome is a clearer product decision and a better question for the label, not a rule for your body.

The model can be updated as the app changes, so a score also belongs to a model version and to the data available at calculation time. A rescore may follow a newer FoodScore rule or more complete source data. That does not mean a product suddenly became a different object; it means the recorded inputs or calculation changed. Read a changed score with the record context, especially where the detail page identifies incomplete data, warnings, or a category-specific rule.

Use the score to narrow a busy label into questions you can answer. Which dimensions explain the total? Is the ingredient list present? Does the displayed variant match the pack? Those checks preserve the useful part of a summary without asking a number to settle choices that depend on price, taste, culture, availability, or how you intend to use the product.
