Tolerance, re-imagined
One app. Eight intolerances. Zero guesswork.
Scan the barcode, see your personal traffic-light — based on your profile, not an average table. Over 400 researched trigger ingredients, seven languages, offline.
Not a substitute for medical advice — complements your therapy.
The problem
Every ingredient list is a riddle.
Tolerance depends not just on whether something is present — but on how much, in what position, with which enzymes, and at what severity.
From barcode to traffic-light in a second.
Three steps, one score. Toleah identifies the product, matches it against your profile, and shows you a personalised traffic-light — completely offline.
Toleah reads the ingredients and checks every trigger.
Personalised traffic-light and tap for details.
What the engine does — and what it doesn’t.

Markus & Sarah

Dr. Miller
Dietitian, own practice in Cologne
Clients report in-session what they remember. Real-life daily data is missing — guidance stays partly guesswork.
Clients voluntarily share scan history via QR-consent. Practice dashboard in preparation (v1.2).
- Scan history as a conversation basis in consultations
- PDF notes export for personal records
- GDPR Art. 9 compliant, audit-logged, revocable
"Toleah gives me a first glimpse into what my clients eat between appointments."

Data shared with her dietitian
Sharing enabled, 30-day access. Guidance now grounded in real daily life, not a paper questionnaire.
Lena is an archetype, not a script. Toleah adapts to your life, not the other way around.
Your traffic-light, not anyone's.
Toleah starts at one hundred points. Each ingredient is checked against your active intolerances, weighted by its position, multiplied by your severity, and — if you take the matching enzyme — adjusted upward in a scientifically conservative way. That's why two people see different traffic-lights for the same product.
Aged parmesan
Your score 58 With consideration
One product — two profiles, two traffic-lights.
Toleah does not compute an average rating. Every scan runs through your own profile — intolerances, severity, enzymes you take. Two people, the same product: potentially two different traffic-lights. That is what sets Toleah apart from "database apps".
One scan. The whole family.
Kid lactose-intolerant, partner histamine-intolerant, you react to sorbitol? Toleah scans once and returns a separate traffic-light for every family member. No parallel apps, no mental arithmetic.
Patterns you can't see alone.
A cramp three hours after lunch. Was it the bread, the cheese, the sorbitol jam? The symptom diary links your entries with the products you scanned and turns single signals into a pattern.
- Bloating
- Fatigue
After lunch at the office — bread with cheese.
- Cramps
Two hours after dessert with sorbitol jam.
- Headache
How people use Toleah.
-
I'd spent years guessing what triggers my migraines. With the diary plus scans it took three weeks to see it: aged cheese plus red wine on weekends. My list is now specific instead of vague.
-
Two kids, my husband, all three sensitive in different ways. A family shop used to take thirty minutes. Now I scan once, see three traffic-lights at the same time — the cart is full in ten.
-
Patients used to bring me lists from the internet that we'd have to sort through together. With practitioner sharing I can see the scan history and the symptom diary directly — the first consult is grounded so much faster.
