Best food scanner apps in the UK,
seven, compared.
A scanner is a fast way to read a UK pack: point the camera, get the ingredients, the additives and the nutrition panel back. Here are seven UK shoppers actually use in 2026. We start with ours because we built it. We mark that clearly throughout.
What a scanner does.
The barcode goes to a database; the database returns the ingredient list, nutrition panel and, depending on the app, a flag or a score. The differences are in the database, the flags and what the app does after the scan.
The database is the bit that matters
Coverage of UK supermarket packs varies. Some apps lean French, some American, some are community-built. We built NutraSafe around Tesco, Sainsbury's, Asda, Morrisons, Aldi, Lidl, Co-op and Waitrose own-brand plus branded.
The flag is what you read
Plain-English flags on additives and allergens beat letter grades. We surface the regulator (EFSA, FSA, NHS, WHO, IARC) on every flag, so a flag isn't an opinion.
Logging is the bit you forget about
Most apps add the food to a day total. The question is whether the totals are useful afterwards. Calories alone are one number. Calories plus macros plus vitamins plus minerals plus additives across a week tell you something.
The free tier limits set the test
Most apps have one. Read it carefully. NutraSafe's free covers 25 food logs a day and 5 reactions; Pro is £3.99 a month or £34.99 a year. Yuka's free is generous; Pro adds personalised recommendations. MyFitnessPal's free shows ads; Premium removes them.
The seven apps.
Picked because UK shoppers actually use them. Described as we see them, not graded.
1. NutraSafe (us)
UK iPhone app. Scan a pack, get the ingredient list, the additive flag in plain English, the Big 14 allergen check, calories and macros. Vitamins and minerals against UK NRV on Pro. Reaction diary, fasting, workouts, AI Coach. Free download. Pro £3.99 a month.
2. Yuka
French app, big global brand. Scans a barcode and shows a letter-graded score plus additive flags. UK supermarket catalogue is patchy; database leans French. Free with a paid tier for personalised recommendations.
3. MyFitnessPal
The category default for calorie counting. Huge user-generated database, which means breadth but also inconsistency. Barcode scanner reads UK packs; doesn't do additive flags or Big 14 detail. Free with ads; Premium tier paid.
4. Open Food Facts
Free, open-source, community-built. Anyone can add a product. UK coverage is genuine and growing. Plain-text ingredient list and additive list per pack. No AI, no coach, no diary in the same sense as a tracker.
5. FoodSwitch UK
Built with Action on Salt at Queen Mary University of London. Scans a UK barcode and offers swap suggestions for lower salt, sugar or saturated fat. Narrow but useful. Free. No reaction diary or vitamin tracking.
6. Nutracheck
UK calorie counter with a curated own database. Strong on UK supermarket coverage, smaller community than MyFitnessPal. Calorie + macro focus. Free Lite plus paid tier.
7. Lose It!
US-built calorie counter with a Snap-It photo-recognition feature. UK supermarket coverage exists, smaller than MyFitnessPal. No additive flagging, no Big 14 detail. Free with paid Premium.
Which scanner,
for what.
Pick by the question you're actually trying to answer.
"What's in this UK pack?"
NutraSafe (us), Open Food Facts, Yuka. NutraSafe and Open Food Facts are best on plain-English ingredient detail. Yuka adds a score; we don't.
"How many calories is this?"
MyFitnessPal, Nutracheck, Lose It!, NutraSafe. All four log calories from a barcode. MyFitnessPal has the biggest community; Nutracheck has the cleanest UK catalogue; NutraSafe joins it to vitamins, additives and reactions.
"Help me cut salt or sugar"
FoodSwitch UK is the specialist. NutraSafe shows salt and sugar on every scan against your day's UK NRV totals; it doesn't suggest swaps.
"All of the above in one app"
That's us. One diary; food, additives, allergens, vitamins, reactions, training and fasting in the same place. Free covers the basics. Pro £3.99 a month or £34.99 a year.
A 330ml can,
what we show.
Coca-Cola Original. The classic question: what's the E150d doing there? Here's the scan.
From the UK panel. Logs to your day.
Counts against your day's sugar total alongside everything else you log.
Sulphite ammonia caramel. IARC Group 2B (2013), possible carcinogen. We say so, source on the line.
None in the ingredients we have. Not "none in the product". Cross-contact lives on the pack.
Frequently
asked.
Pulled from the support inbox and the App Store reviews.
It depends on what you want to do. We built NutraSafe for UK shoppers who want barcode scanning, additive flags in plain English, allergen alerts and vitamin and mineral tracking against UK NRVs in one app. Yuka leans on additive scoring. MyFitnessPal leans on calories and a large user-generated database. Open Food Facts is community-built and free. Pick by use case.
Yes, several. NutraSafe is free to download with up to 25 food logs a day and barcode scanning. Yuka has a free tier. MyFitnessPal is free with ads. Open Food Facts is free and open-source. FoodSwitch UK is free.
Read a UK barcode, show the ingredient list and nutrition panel, flag additives and Big 14 allergens in plain English, and log the food to your day. Our app, NutraSafe, also tracks vitamins and minerals against UK NRVs on Pro.
Yes. Yuka and NutraSafe both flag additives. We check every E-number when you scan a barcode and surface the Southampton Six that carry the mandatory UK hyperactivity warning.
No. A scanner is a faster pre-check. The on-pack ingredient list is the source of truth. Manufacturers reformulate; "may contain" warnings are voluntary; a new batch may differ. We never say "no allergens in this product"; we say "none in the ingredients we have".
Scan any UK pack.
We tell you what's in it.
Free download. Up to 25 food logs a day on the free tier. Pro £3.99 a month or £34.99 a year for AI Coach, workouts, fasting and the suspected-triggers view.
