Honest by design

What other scanners miss.

Most apps hand you a number. Chue shows the published decision behind it, and flags the hazards the others quietly skip.

Reflects each app's publicly described approach; features may change. Chue cites every decision in the app, so you can verify it yourself.

Illustrative example
A snack cookie with TBHQ and Red 40
14Chue ยท capped
A typical scanner marks the additives "risky" and moves on. Chue caps the score and cites the actual decisions: TBHQ is banned in Japan, and Red 40 carries an EU school-warning rule for 2027. You see who decided, and when.

Stop guessing at the grocery store.

Questions

Frequently asked.

What does "Chue" mean?โŒ„

It is true plus chew. Chue helps you see what is true about what you chew: an honest, regulator-backed score on every food and product you scan.

What does Chue actually score?โŒ„

Every product gets one number from 0 to 100. The score combines Nutri-Score (60 percent), additive risk (30 percent), and organic certification (10 percent). A hazardous additive or a Nutri-Score of D or E caps the result at 49.

Where does the data come from?โŒ„

Open Food Facts and Open Beauty Facts for product identity. Nutri-Score for nutrition. Regulatory cross-reference against FDA, EFSA, IARC, ANSES, JECFA, NTP, and California Prop 65. EPA SDWIS for tap water.

Is Chue free?โŒ„

Yes. Unlimited barcode scans, hazard flags, banned-abroad warnings, multi-source citations, save and blacklist. All free, no account needed for your first 50 scans.

Do brands pay to look good?โŒ„

No. Zero brand money. No sponsored scores. No verified-clean badges sold to manufacturers. Revenue comes only from Premium subscribers.

Why a hard cap at 49?โŒ„

Because a single hazardous additive (something a regulator has classified as carcinogenic, banned in another market, or restricted) is not redeemed by fortified vitamins elsewhere. The ceiling is the honesty signal.

What if a product isn't in the database?โŒ„

Chue falls back to photo search. Aim at the ingredient panel. You can also contribute the product to Open Food Facts in two taps so the next person scanning the same brand gets a hit.

What about my tap water?โŒ„

During onboarding you enter your ZIP. Chue pulls EPA Safe Drinking Water records for the public utility serving you and grades the last five years of violations on the same 0 to 100 scale.
