What's really in that?

The UK calorie counter that catches hidden additives. Scan a barcode, see calories and macros alongside every E-number behind them, and spot what keeps making you feel off.

Most calorie counters tell you what's on the label. We tell you what's in it — every ingredient, every additive, what each one does if you eat it often. Log what you ate and how you felt after. After a few weeks you'll start seeing the patterns. No single-letter verdicts, no telling you off, no spreadsheet.

What changes after a month.

Six things you might start to notice. Pick whichever sounds like you.

i.

You'd read the back, not the front.

Scan a barcode and we'll show you every additive and what it does — the bits the marketing team would rather you missed.
ii.

You'd know where the week falls short.

Log what you'd eat anyway. We work out the vitamin and mineral gaps against UK NRVs and show you the trend, not a panic chart.
iii.

You'd see what keeps making you feel off.

Log what you ate, log how you felt after. The timeline shows what keeps cropping up. We don't diagnose — you just see the pattern.
iv.

You'd see your week add up.

Calories, macros, sets, reps, fasting windows — collected on one page. No second app. No spreadsheet.
v.

You'd stop guessing what's "ultra-processed".

Every food we scan gets a processing grade and we show the working — additives, ingredient count, refining steps. No letter pulled from nowhere.
vi.

You'd have something to take to the dietitian.

A clean record of what you ate and how you felt — useful for a dietitian appointment, useful before paying for an IgG test you don't actually need.
We don't tell you what's wrong. We help you spot the pattern.

§ 02  —  The four working parts

Scan. Read. Decide for yourself.

Four parts of the app. Each one shows you what's there. None of them tell you what to put in your trolley.

Point your phone at a barcode.

Scan any UK supermarket barcode and you'll see the full ingredient list, with every additive named and explained — including the bits the front of the packet wants you to skim past.

No single-letter verdict. No "avoid this" label. We just show you what's in there, what each ingredient actually does if you eat it a lot, and let you decide. Covers UK supermarkets: Tesco, Sainsbury's, Asda, Morrisons, Aldi, Lidl, M&S, Co-op, Waitrose.

Notice what keeps making you feel off.

Log what you ate. Log how you felt after. After a few weeks the timeline shows what keeps cropping up.

It's a journal, not a diagnosis. Anything acute is a GP job — anaphylaxis is 999. What we're good for is the slow stuff that's hard to spot in your own head, and a clean record to take to a dietitian when you go.

Composition panel No. B · reactions
  • Reactions logged by symptom, time and intensity
  • Co-occurrence timeline against recent meals
  • Suspected-trigger surfacing (Pro)
  • Export the lot for a dietitian appointment

Vitamins, without the spreadsheet.

Log what you'd normally log. We work out which vitamins and minerals the week's been short on against UK NRVs, and show you where it came from.

The vitamins and minerals printed on the back of a UK label, plus the ones the NHS actually publishes guidance for. No supplement upsell, no scare-chart, no red bars yelling at you. Just the trend, week by week — somewhere to check when you're wondering why you've been feeling rubbish.

Composition panel No. C · vitamins
  • Tracked against UK NRVs, not American RDAs
  • Days-achieved view instead of brittle daily averages
  • Source breakdown showing where each nutrient came from
  • Not a substitute for a blood test — see your GP if symptoms persist

One app for food, lifting and the fasting window.

A workout tracker that catches your PBs. A fasting timer with 16:8, 5:2 and the rest. An AI coach that's read your diary — not a generic chatbot.

All built on the same diary. The Coach reads what you logged today. The fasting timer remembers yesterday's window. The workout tracker auto-detects your PBs. One app, not five tabs of separate state.

Composition panel No. D · the rest
  • Workout tracker with rest timer, PB detect, Apple Watch
  • Fasting timer with 16:8, 18:6, 20:4, 5:2 and OMAD
  • AI Coach that reads your own diary (Pro)
  • AI meal scan for plated food without a barcode (Pro)

§ 03  —  In practice

Three things to do. Nothing complicated.

A scan at the shop. A few taps after a meal. A look at the week when you fancy it.

01

Scan a packet.

Camera at the barcode. We read the ingredients, name the additives, and tell you what we know about each one.

02

Log a meal.

Search, scan, or describe a plate to the AI. If you felt off afterwards, tap a reaction. Takes seconds.

03

Read the week.

Open it on a Sunday. The trends, the gaps, what kept making you feel off — all on one page.

§ 04  —  Questions, answered

Common questions.

We scan UK supermarket barcodes and tell you what's in the food — every E-number named, every additive explained, the processing grade with the reasoning shown. We don't issue single-letter verdicts. UK supermarkets: Tesco, Sainsbury's, Asda, Morrisons, Aldi, Lidl, M&S, Co-op, Waitrose. Free to use up to 25 scans a day, NutraSafe Pro £3.99/month.

Scan a UK barcode in our app. We identify every E-number in the ingredient list, name it, and explain what it does — and what it tends to do to a body that eats it often. E100s are colours, E200s preservatives, E300s antioxidants, E400s thickeners, E600s flavour enhancers.

Yes. Log what you eat and we'll track your vitamins and minerals against UK NRVs — the ones printed on the back of a label plus the ones the NHS publishes guidance for. Days-achieved view rather than a brittle daily target. Vitamin and mineral tracking is part of NutraSafe Pro (£3.99/month). Most calorie counters skip micronutrients entirely or charge significantly more.

Log what you ate. Log how you felt afterwards. Our reaction tracker shows you what tends to crop up next to what — over weeks, not minutes. It's a journal, not a diagnosis: useful for spotting slow patterns and for taking a clean record to your dietitian. For acute symptoms see a GP; for anaphylaxis, 999.

We're built for UK supermarket products — Yuka uses a French database. We track vitamins and minerals against UK NRVs; Yuka doesn't. We've got a reaction tracker, a workout tracker, an AI Coach that reads your own diary, and a fasting timer. We don't issue single-letter verdicts on your shopping.

NutraSafe Pro is £3.99/month against MyFitnessPal Premium's £15.99/month — about £156 a year less. We add UK-specific stuff MyFitnessPal doesn't: barcode additive detection, E-number explanations, vitamin and mineral tracking against UK NRVs, allergen alerts. No ads on the free tier.

The download is free. You can log up to 25 foods a day and 5 reactions on the free tier — enough to try it. NutraSafe Pro is £3.99/month and lifts both caps, adds the AI Coach, AI meal scans, fasting, full reaction history, the suspected-trigger view, and vitamin/mineral tracking against UK NRVs.
