The short answer
Yuka says its food score weights nutritional quality at 60%, additives at 30% and organic status at 10%, with a cap when it identifies a high-risk additive. Optimally is a primal-inspired food guide that scans barcodes, photographs labels and meals, and explains its editorial food-quality rating alongside meal ideas and food logging. The apps use different lenses; neither score is a clinical verdict. Optimally publishes this comparison itself, so use the feature descriptions and your own products to decide what fits.
The scoring approaches
Yuka’s help page describes a nutrition-led formula using Nutri-Score for 60% of the food score, additive presence for 30%, and an organic dimension for 10%. It says products with additives it classifies as high-risk cannot score above 49. These are the criteria Yuka publishes about its own app.
Optimally’s rating applies its editorial criteria to available ingredient and nutrition information, within a primal-inspired focus on whole foods and micronutrients. It explains its results but is not a clinical scale or a comprehensive nutrient calculation. The app does not check strict Primal or Ray Peat compliance.
What you can do in Optimally
Optimally supports barcode scanning, ingredient-label photos and meal photos. It also offers whole-food meal ideas and a food log, with available vitamin and mineral context. That makes it useful when you want to move from “what is in this package?” to “how might I build a meal I enjoy?” The data may be incomplete, so check the label and treat missing values as unknown.
Try the same packages in both apps and see which explanations are most useful to you.
A fair comparison uses a real shopping example
Try a plain and a flavoured yoghurt, or two packaged sauces. Scan each barcode where possible and compare the ingredient details with the actual package. Ask whether you want a nutrition-and-additives score, an ingredient explanation, meal ideas, or a place to log what you eat. Include serving size and any allergies in your decision; the FDA notes that Nutrition Facts amounts refer to the stated serving, and allergen checks belong on the current package.
Optimally is a paid iPhone app, and current availability and purchase details are shown in the App Store. Yuka’s pricing and feature availability may vary by market and plan; check each app’s current listing rather than relying on dated claims.
Limits worth keeping in view
A score cannot tell you whether you have a nutrient deficiency, guarantee allergen safety or predict a medical outcome. Optimally’s scores are editorial, not clinical; Yuka’s formula is its own published method. Neither app replaces the physical package or individualized medical advice. Optimally is built for people who want food explanations, meal inspiration and a micronutrient-aware, primal-inspired direction—not a universal ranking of every scanner.
