How does Ethara calculate the scores?

From public ESG reports, vetted business press, sector NGOs, and moderated community reports. Every score is sourced, traceable, and reviewed twice a year by an independent editorial team.

Yes, entirely free. No ads, no affiliate commission. Funded by donations and an optional Pro subscription for advanced research.

Can a brand pay to change its score?

No. Ethara is strictly independent. No brand can pay to alter its score or remove an analysis. Without that independence, the score is worthless.

What if I think an analysis is incorrect?

Every detail screen has a “Report” button. The editorial team reviews each remark and can update a sourced score.

Ethara vs Yuka: what's the difference for your online shopping?

Last updated: 6 May 2026 · Author: Tugdual Launay, founder of Ethara

Ethara and Yuka are two French mobile apps that help consume better, but they don't cover the same scope. Yuka rates physical products (food, cosmetics) by scanning a barcode. Ethara rates websites and merchants on their overall practices (ecology, working conditions, taxation, dropshipping, animals, health, diversity).

When to use Yuka

Yuka excels at:

Checking the composition of a yogurt at the supermarket.
Identifying endocrine disruptors in a sunscreen.
Comparing two toothpastes in the hygiene aisle.

Limit: Yuka says nothing about the brand itself (working conditions, taxation, dropshipping). A Yuka-rated product scoring 100/100 can still be sold by a site that uses dropshipping or pays workers below local minimum.

When to use Ethara

Ethara excels at:

Checking an unknown online retailer before ordering.
Spotting dropshipping hidden behind a "trendy boutique".
Aligning e-commerce purchases with values (ecology, social, fiscal).
Finding better-rated alternatives in the same category.

Limit: Ethara doesn't evaluate the composition of an individual product. For that, Yuka remains relevant.

Are the two apps complementary?

Yes. Typical use case:

You discover a new online retailer → Ethara to verify the brand.
You evaluate a product in-store → Yuka to scan the barcode.
You buy a food or cosmetic product online → both, combined.

Differences on the ecological dimension

Aspect	Ethara	Yuka
Brand carbon footprint	Evaluated	Not evaluated
Product composition	Not evaluated	Evaluated (Eco-Score on food)
Packaging	Evaluated globally	Not evaluated
Production conditions	Evaluated	Not evaluated

Is there an alternative to Yuka for online shopping?

Yes: Ethara. Yuka doesn't cover general e-commerce. To evaluate a site before ordering a garment, furniture, tech gear, or fashion products, you need an app that rates the brand and merchant, not just the physical product.

Frequently asked questions

Does Ethara replace Yuka? No, they don't cover the same scope. Yuka = physical products. Ethara = websites and brands. Both are useful together.

Does Yuka rate brands? Yuka rates products, not brands. Two products from the same brand can have very different Yuka ratings.

Does Ethara rate food? Ethara rates food retailers (Carrefour, Picard, Greenweez…) on their overall practices. For a specific yogurt's composition, Yuka is more appropriate.

Are both apps independent? Yes. Neither Ethara nor Yuka accept payment from brands to change a score.

On which devices is Ethara available? iOS 16+ and Android 11+. A Chrome and Firefox browser extension is in the works for late 2026.
