How can we help?

An app that explains packaged food, drinks and beauty products. Scan a barcode to see a score from 0 to 100, the reasons behind it, the full ingredients and allergens, and a better product of the same kind when there is one.

Yes. Scanning, scores, product details, history, favourites, Better and the Basket Score are free with an account. Premium adds search, personal alerts for allergens, diets and ingredients you avoid, more Better suggestions and offline access.

In the UK, £0.99 a month or £9.99 a year. Both plans include the same features and start with a 7-day free trial, one per Nutivio account. You subscribe through the App Store or Google Play, and the app shows the price your store will charge before you confirm.

Out of 100, in three parts: nutrition (up to 65 points), additives (up to 20) and processing (up to 15). 80 and above is Excellent, 60 to 79 Good, 35 to 59 Poor and below 35 Bad. Every product page shows what raised or lowered its score.

From their ingredient list, checked against EU cosmetics rules and published safety opinions. Labels don't show amounts, so a flag describes the ingredient, not how much of it is in the product.

From Open Food Facts and Open Beauty Facts, open databases built by volunteers, used under the Open Database Licence, with photos under Creative Commons BY-SA. Our team corrects mistakes, and details sent by customers are only used after review. Every product page shows its source.

If too much key information is missing, Nutivio doesn't show a score at all. We'd rather say nothing than guess.

No. Scores are calculated the same way for every product, there are no adverts, and no brand or shop can pay to appear as a Better suggestion.

No. With Premium, your preferences appear as separate alerts on each product: Contains, May contain, or Can't confirm when data is missing. Nutivio never labels a product as safe, so always check the pack, especially for allergens.

With Premium, products you've scanned, saved or favourited stay on your phone, encrypted, for up to 30 days and up to 500 products. They're removed when you sign out. A barcode you've never scanned needs a connection.

You can send us a few photos of the pack from the app. Our team reviews them before the product is added, so the next person who scans it gets an answer.

So your history, favourites, preferences and Premium follow you to a new phone, even between iPhone and Android. We ask only for your first name, an email address and a password.

In your App Store or Google Play subscription settings, at least 24 hours before the renewal or trial end date. Deleting the app or your account doesn't cancel a subscription. You keep Premium until the end of the period you've paid for.

Yes, at any time, in the app under Account, then Privacy. You can export a copy of your data or delete your account.

No. Nutivio describes products, not your health. Always check the label, and ask a doctor, dietitian or pharmacist for advice about your diet or skin.
