Yuka is the app that taught the world to scan groceries, and it deserves the credit: ~85 million users, fiercely independent, and genuinely free. If you want one universal read on a product, it's excellent.
Rootd exists because of the question Yuka can't answer: healthy for whom? A granola bar can be a great choice for a protein-focused runner and a poor one for someone cutting sugar with a nut allergy. One number for everyone means the number is personal for no one.
| Yuka | Rootd | |
|---|---|---|
| How scores work | One universal 0–100 for everyone | A personal 0–100 per user — your goals, allergies, and dealbreakers change the score |
| Score transparency | Single number with broad factors | Every score itemized point by point, so you see exactly why |
| Allergies & strict diets | Fixed diet alerts; explicitly not for allergy use | Allergen, religious, and diet conflicts hard-block to 0, with cross-contact warnings — and we still say: verify the label |
| Strictness | One-size verdicts | You choose relaxed, balanced, or strict — and the scoring genuinely changes |
| Education | Product ratings | A full lesson library with quizzes, citations, and a carrot DJ |
| Price | Free; optional premium (~$10–20/yr) | Free scanning; premium $4.99/mo or $39.99/yr with a 7-day free trial |
| Scale | ~85M users worldwide | Brand new — and personal by design |
Honest bottom line: if you want a quick, free, universal verdict, Yuka remains a fine choice. If your eating has rules — allergies, religious practice, specific goals, ingredients you avoid — you deserve a score that knows them. That's what Rootd was built for, by one person who used to be a devoted Yuka user.
