Find out what really doesn't agree with you. Food diary + symptom diary + AI pattern analysis. Private, honest, no diet pressure.
Find out what really doesn't agree with you.
Tago brings together a food diary and a symptom diary and shows you statistical links between what you eat and how you feel. For anyone who has lived with bloating, IBS, tiredness or skin problems for years and finally wants to see clear patterns — without expensive tests.
––––– WHAT TAGO DOES –––––
AI PHOTO SCAN
Point your phone at your plate. The AI recognises the ingredients and estimates calories and macros in seconds. Restaurant menus are captured in full too, including allergen warnings.
BARCODE SCANNER
Scan packaged products with your camera: millions of products from Open Food Facts, with ingredients and allergens. Allergens are recognised in English, French, Spanish, Italian and German ingredient lists.
VOICE INPUT
Just say what you ate — Tago turns it into diary entries.
SYMPTOM DIARY
Track stomach pain, bloating, diarrhoea, constipation, heartburn, headaches, tiredness or skin reactions — with severity, time and, optionally, the Bristol stool scale.
PATTERN ANALYSIS
After 14 days Tago finds first patterns: “On days with milk, stomach pain followed 3× more often.” With reaction time, confidence and lift values — transparent, not a black box.
ELIMINATION TESTS
Suspect an ingredient? Start a 7-, 14- or 21-day test. Tago compares your symptoms before and after and gives a clear verdict: confirmed, ruled out or unclear. No fooling yourself.
AI ANALYSIS REPORT
A detailed report: which intolerances are likely (lactose, fructose, histamine, FODMAPs), how solid your data is and which next steps make sense.
FOX ASSISTANT (PRO)
Your fox learns your tracking routine and gently asks when something is missing today. Runs entirely on your device.
APPLE HEALTH
Two-way sync: steps, workouts, weight and water feed into the analysis, and results go back to Apple Health if you like.
COACH & FRIENDS (PRO)
Share your diary with your coach, dietitian or partner. Chat, comments and shared insights in a private space.
