About this app

Know what's in it, and what it means for you.

KaiScan scans any packaged food's barcode and instantly shows you two things: an honest, objective score for the product, and a personalised fit calculated for YOUR health conditions and country.

THE KAISCORE: one honest score
Every product gets a 0 to 100 score, graded A to E, blending:
• Nutrition, two thirds of the score (energy, sugar, saturated fat, salt, fibre, protein)
• Additives, one third (every E-number classified by risk, and explained, not just listed)
• Plus a genuine bonus for certified organic
The same score for everyone, so you can compare two products in a glance.

A SCORE MADE FOR YOUR BODY
The label is the same for everyone. You aren't. Tell KaiScan your health conditions once and every product gets a second score, yours, with a plain verdict: Good fit, Go easy, or Not ideal. It's calibrated to your country's daily guidance (WHO, EU, UK, US FDA, India's ICMR or AU/NZ), with WHO as the worldwide fallback. And it's safety-first: if a product is bad for even one of your conditions, your personal score stays low.

27 conditions supported: diabetes, hypertension, heart, kidney, high cholesterol, weight management, PCOS, IBS, thyroid, gout, fatty liver, pregnancy, and the major allergies (gluten, milk, peanut, tree nuts, soy, egg, fish, shellfish, sesame, lactose and more).

ALLERGIES, HANDLED HONESTLY
KaiScan tells "contains" apart from "may contain traces." A declared allergen is a hard avoid; a precautionary trace is a clearly labelled caution. Precise matching means a coconut is never mistaken for a tree nut: no crying wolf, no quiet misses. Always check the physical packaging too.

EVERY ADDITIVE, EXPLAINED
Tap any E-number for its category, what it does, any potential associated risks, and public sources (EFSA, IARC, ANSES, WHO). Educational and referenced.

YOUR KAISCAN COACH
A short, plain-language take on what a product means for you, grounded strictly in the rules, never hype.

SMARTER ALTERNATIVES
"Try instead" surfaces a similar product that's genuinely better for your conditions, never something that fits you worse, and never an item still unsafe for your allergy.

COMPARE • SAVE • TRENDS
Compare two products head-to-head for your profile, save a per-condition safe list, and watch your weekly scan trends.

EIGHT LANGUAGES
English, French, German, Spanish, Italian, Portuguese, Dutch and Polish.

PRIVACY-FIRST
Your health conditions are stored on your device only, never on our servers. We don't sell your data and we don't show ads.

FREE, WITH A FAIR TRIAL
The core score, nutrition breakdown, additive explanations and allergen flags are free. Premium (personalised fit, coach, condition-tuned alternatives, compare and trends) comes with a genuine 168-hour free trial: a full 7 × 24 hours counted from the moment you start it, so you never lose a day.

Educational, not medical advice. KaiScan draws on general dietary guidance from the WHO, FDA, NHS and ICMR. It doesn't diagnose or treat, and it isn't a substitute for a qualified clinician. Always read the product's own packaging, especially for allergies.
