What Toleah does. And why.

The eight core features

• Barcode scanner

  Camera-based on iOS and Android, directly in the browser as a PWA, manual EAN entry as a fallback. From barcode to traffic-light in under a second. Example: you stand in front of a wall of chocolate bars — one scan per bar, and in ten seconds you've sorted three options.

• Personalised scoring

  Over 400 trigger definitions, eight intolerances, three severity levels, seven enzyme profiles, position weighting, cross-intolerance detection. No rigid "contains yes/no", just a number that fits you. Example: you take lactase with meals. Toleah adjusts your traffic-light for lactose-containing products dose-dependently — where the evidence supports it.

• Family mode

  Up to twenty profiles with their own intolerances, severities and enzymes. One scan shows you in parallel who in the family tolerates what. Example: kids' birthday, ice-cream options. Three of the invited friends have intolerances. One scan per flavour, four traffic-lights per scan.

• Symptom diary

  Short entries with time, symptom and intensity. Toleah links them automatically with the products you scanned and surfaces correlations across weeks. Example: you log bloating for three weeks. The dashboard shows: on five out of seven days something with sorbitol was on the menu two hours earlier.

• Recipe book

  Curated recipes, automatically scored against your profile. Filter by prep time, difficulty, tags (vegan, gluten-free, meal-prep). Example: you open the cookbook, filter by "quick" and only see recipes that come out green for you. No post-cooking disappointment.

• Practitioner bridge

  Share your symptom diary, scan history and shopping list selectively with your nutritionist or practitioner. Every share is audit-logged and revocable at any time. Example: before your quarterly appointment you unlock the last four weeks. Your practitioner spots the patterns, you talk about next steps instead of trying to remember last month.

• Offline capability

  Seven-day local cache, five-step API fallback cascade. The scanner works where the signal doesn't. Example: the hotel Wi-Fi drops during your breakfast run. Your latest scans stay available, new products are checked against the cache.

• Seven languages

  German, English, Spanish, French, Italian, Dutch, Portuguese — not only the UI. Trigger definitions are curated per language. Example: holiday in Italy. The ingredient list is Italian — Toleah recognises "latte intero" as readily as "whole milk".
