What a food health scanner does
A food health scanner turns the label you can barely read into an answer you can act on. You point your phone at a product's barcode, the app looks it up in a food database, and in a second or two you see what's actually inside: the ingredients, the nutrition, often a health score, and any allergen or additive warnings. Instead of squinting at the back of two packets in the aisle, you get a clear read and can pick the better one.
An app is only as good as its data and its scoring, and both vary a lot. Scrannr runs on Open Food Facts — a free, open, community-built database often called the "Wikipedia of food" — with real UK coverage, and it turns each product into a single 0–100 health score you can compare at a glance.
A health score
One 0–100 number from a product's nutrition and ingredients, so you can compare two packets fast.
Full nutrition
The nutrition breakdown, including the salt, sugar and saturated fat UK guidance suggests limiting.
Allergen data
The allergens on file, surfaced on every scan so you can spot what to avoid.
Additive flags
The additives and E-numbers worth a second look, flagged in plain English rather than jargon.
An honesty note. A food health scanner is a fast way to compare products, not a medical verdict. The score is guidance built from nutrition and ingredients, and allergen data can be incomplete — so if you have an allergy, always read the product label.
What you see
Everything a health scan shows you.
One scan unpacks a product four ways — the score, the nutrition, the allergens and the additives — so you're not decoding tiny print in the aisle.
Allergen data on every scan
Every scan pulls out the allergens recorded for that product, so what to steer clear of is right there.
Full nutrition breakdown
See the nutrition behind the score, including the salt, sugar and saturated fat UK guidance suggests keeping an eye on.
Additive & ingredient flags
The additives and E-numbers worth a second look, named in plain English instead of code.
Are additives safe?

The score
How Scrannr scores food 0–100.
One number, so you can compare two products in the time it takes to pick one up.
Every scan gives you a single number from 0 to 100, and higher is better. The score is built from two things: the product's nutrition and its ingredients. Broadly, a product scores better when it's lower in the nutrients UK health guidance suggests most of us should cut down on — such as saturated fat, salt and sugar — and when its ingredient list is simpler, with fewer additives flagged. Alongside the number you get a short, plain-language verdict.
The score is a way to compare products quickly, not a formula we publish or a medical judgement. It doesn't know your portion size or the rest of your day, and — like any scanner — it's only as complete as the underlying data. See exactly how the health score works.
Built for UK shopping
Plenty of food scanner apps are built for US shelves and fall flat in a British supermarket — many of your weekly-shop products simply won't scan. Scrannr is made in the UK and built around British products and supermarket own-brands, so the everyday items in your trolley are the ones it recognises.
It runs on Open Food Facts, which holds around 190,000 UK products, and coverage keeps growing as the community adds and improves entries. Your scan history stays on your device, and you don't need an account to start — so you can check your food without handing over personal data.
FAQ
Food health scanner, answered.
What is a food health scanner?
A food health scanner is a phone app that reads a product's barcode, looks it up in a food database, and turns the small print into something you can read at a glance — usually a health score, the nutrition, the ingredients, and any allergen or additive warnings. Scrannr gives every scanned product a clear 0–100 health score built from its nutrition and ingredients.
Is Scrannr free?
Yes. The core app is free — five full analyses each month, with nutrition, allergens, product search and dietary profiles always free and no account required. Premium (£2.99/month or £14.99/year, 3-day free trial) removes the monthly cap for unlimited analyses.
How accurate is the health score?
It's built from each product's nutrition and ingredients using Open Food Facts data, and it's meant for comparing products at a glance — not medical or nutritional advice. Where a product's data is thin, so is the score. See how the health score works.
Does the food health scanner work in UK supermarkets?
Yes. Scrannr is made in the UK and built for British shopping, including supermarket own-brands. Product data comes from Open Food Facts, which holds around 190,000 UK products, and coverage keeps growing as the community adds and improves entries.
Which foods can I scan?
Most packaged food and drink with a barcode. Scrannr looks products up online, so you need a connection to scan something new; products you have already scanned stay in your history.
Is my data private?
Yes. Scrannr keeps your scan history on your device and needs no account to start, so you can check your food without handing over personal data.
