02 What lands in the diary when you scan

One barcode,
seven answers.

You point the camera, we look up the pack, and the diary fills in. Calories add to the day, additives get named, allergens get flagged, the vitamins move a few percent towards the UK NRV. Then you carry on with your shop.

i

Calories and macros off the panel.

Kcal, sugar, carbs, fat, protein, salt. We read what the manufacturer printed and add it to your day, against a daily calorie target you set.

ii

Every E-number, in plain English.

We check each ingredient against the additive library. What it is, where it shows up, and, where a concern exists, what the regulator has said.

03 What a real scan actually shows you

The nutrition panel comes off the back of pack. We pick out the additives in plain English, highlight any of the 14 UK allergens, and the calories add to your day against the target you set.

If a UK barcode exists in the food databases, the scanner reads it.

05 Questions people ask

Frequently
asked.

Nine questions we get in our inbox most weeks. Short answers, no flannel.

What is a food scanner?

A food scanner reads the barcode on a food pack and shows the ingredients, additives, allergens and nutrition panel for that product. We pull from the UK food databases that hold what the manufacturer printed on the label.

How does the food scanner work?

You point your phone camera at a UK barcode (GTIN or EAN). We look the product up, return the ingredient line, every additive in plain English, any of the 14 UK-declarable allergens, and the nutrition panel as printed.

Which UK supermarket products can I scan?

Any UK barcode. The big shops (Tesco, Sainsbury's, Asda, Morrisons, Aldi, Lidl, Waitrose, Co-op, M&S) and the brands they stock are all covered. Independents are hit or miss; we add missing items from in-app reports.

Is the food scanner free?

The download is free. The free tier covers barcode scanning, the full ingredient breakdown, the per-product grade, the public E-number library and up to 25 food logs a day. NutraSafe Pro is £3.99 a month or £34.99 a year on iOS.

What's the difference between a food scanner and a calorie counter?

A calorie counter totals the day. A food scanner reads what's in the pack before you eat it: the order, the additives, the allergens, the panel. We do both, in the same diary.

Does the scanner check for E-numbers?

Yes. Every ingredient is checked against the additive library (480+ entries). Each additive comes back with a plain-English line on what it is and where it shows up; where published evidence exists, what the regulator has said, with the source.

Can I scan restaurant food without a barcode?

AI meal scan lets you photograph a plate and get back an estimate of calories, macros and likely ingredients. Less precise than a barcode scan; useful for restaurant food, home cooking and takeaways. Pro feature.

Does the scanner work without internet?

Previously-scanned products work offline from the diary. A fresh barcode needs a connection to look it up.

What if a barcode isn't recognised?

Search by name, or send the missing pack through the in-app report. Most of the time we add it within a week.
