Scan · Decode · Decide

Scan any barcode. Know what’s inside.

CheckIT turns food labels into plain English. Teaspoons of sugar. Sachets of salt. Traffic-light reading tuned to your lifestyle preference if you’ve picked one — Watching my sugar, Watching my salt, Watching my caffeine, or just General. Free. Works offline. No account needed.

The CheckIT Crew at work in a supermarket aisle — KiP, the red-apple explainer, holds a magnifying glass over a salt molecule and a phone showing a nutrition scan; Dr RooT, the tree-rooted analyst in a lab coat, holds a tablet showing a Food Nutrition Chart; SaK, the green-pear scanner, points a barcode scanner at a product flagging SALT DETECTED. Behind them, the CheckIT wordmark glows as a neon sign — Check in amber, IT in emerald.

How CheckIT works

3 taps then the result.

Point your phone’s camera at any barcode. CheckIT reads the label, decodes what’s really in it, and tells you in plain language — not industry jargon. The whole loop takes about five seconds.

Step 1

Scan

Open CheckIT, point at the barcode. Works offline once you’ve scanned a product before. No login, no sign-up.

Step 2

Decode

Sugar in teaspoons. Salt in sachets. Traffic-light reading (green / amber / red) tuned to your lifestyle preference if you’ve picked one — Watching my sugar, Watching my salt, Watching my caffeine, or General.

Step 3

Decide

Tap Buy, Put back, or Just looking. CheckIT remembers what you decided, no judgement. Your scan history is yours.

What CheckIT shows you

The label, decoded.

Most food labels are written for regulators, not for you. CheckIT translates them into the language your body actually speaks — and surfaces the things the front of the pack doesn’t want you to notice.

Sugar visual

Teaspoons, not grams

4g of sugar = 1 teaspoon. CheckIT shows you the actual teaspoons hiding in a serving. A “low-fat” yogurt with 16g of sugar is 4 teaspoons.

Salt visual

Sachets, not milligrams

0.6g of salt = 1 standard McDonald’s sachet. CheckIT shows you how many sachets are dissolved into a serving. A bowl of soup can be 4 sachets.

Traffic light

Green / amber / red, tuned to your preference

Pick a lifestyle preference and the thresholds tighten on the thing you’re watching. Watching my sugar tightens on sugars; Watching my salt tightens on sodium; Watching my caffeine tightens on caffeine content. General leaves the standard FSA traffic-light thresholds in place.

Hidden sugars

60+ hidden sugar names

Sucrose, maltodextrin, dextrose, agave, glucose syrup, invert sugar, fruit-juice concentrate, and 50+ others. CheckIT catches every one of them and adds them up.

SaK alternatives

SaK suggests better swaps

When CheckIT flags red, SaK (Scan and Know) looks for alternatives in the same category that beat the original on sugar or salt — including products from the I500 community-shop network.

Decision Record

Your taps build the evidence base

Every Bought / Put back / Just looking tap helps the I500 hit-rate evidence base grow. Anonymous by default. No name, no location, just the choice. Read the privacy posture →

Lifestyle-preference profiles

Pick what you’re watching.

Three lifestyle-preference profiles plus a General default. Pick one and the traffic-light thresholds tune to the thing you’re reading for. Switch any time. None of these are medical settings — they’re reading lenses.

Sugar

Watching my sugar

Tighter sugar thresholds. Hidden-sugar names highlighted at every scan. Free-sugars vs. naturally-occurring distinction surfaced where the label allows.

Salt

Watching my salt

Tighter sodium thresholds. Sachets-per-serving framed visibly. Hidden-sodium names (e.g. monosodium glutamate, sodium nitrate) flagged at the ingredient level.

Caffeine

Watching my caffeine

Caffeine content surfaced where labelled (UK regulations require declaration above 150 mg/L). EFSA daily-limit context available via Knowledge Library tap-through.

General

General (default)

Standard FSA traffic-light thresholds. The reading lens you start with before you pick a watch. Always available; never locked.

The Crew of CheckIT

Three voices in your pocket.

CheckIT isn’t a single app voice. The Crew is three characters with three jobs — the explainer, the suggester, and the analyst. Each shows up at the right moment in your scan.

KiP
The explainer
Knowledge is Power. KiP carries the headline verdict at every scan — the teaspoons, the sachets, the traffic light. Plain language. No jargon. Always your first point of contact.
SaK
The alternative-finder
Scan and Know. When the verdict flags red, SaK looks for better swaps in the same category — including products verified at independent shops in the I500 community network.
Dr RooT
The analyst
When you want the deep answer — what does this nutrient actually do, why does the threshold matter, what does the research say — Dr RooT pulls the analysis without making medical claims.
What CheckIT is, and isn’t

A food literacy tool. Not a medical app.

CheckIT is built to help you read food the way it’s actually written. It tells you what’s in the package and what those numbers mean. It does not diagnose, prescribe, treat, or replace clinical advice.

If you’re managing a clinical condition, CheckIT works alongside your GP, dietitian, or specialist nurse — not instead of them. The verdicts it shows are calibrated against published nutritional thresholds; the product advice you should follow is the advice your clinical team gives you.

SCANSMART Ltd does not hold or process medical records. Your lifestyle-preference profile is a reading lens, not clinical data. Per the published privacy posture, CheckIT captures what you scan and what you decide; it does not capture who you are. Full privacy posture →

Open CheckIT. Scan something. See what’s actually in it.
