Culprit helps you find the foods connected to your symptoms β€” not by guessing, but by a structured 14-day elimination phase followed by a guided reintroduction. Each tested food becomes a clear pattern, not a wild guess. WHY CULPRIT IS DIFFERENT Most tracking apps dump a food diary on you and leave you to connect the dots. Culprit runs a proven protocol: remove likely triggers for 14 days, then test them one at a time with a 72-hour washout between tests. You get to the answer in weeks, not months. HOW IT WORKS β€’ Onboarding β€” tell us your symptoms and which food groups you want to test β€’ Elimination Phase (14 days) β€” log meals and symptoms; we calculate your personal baseline β€’ Reintroduction β€” one food group at a time, with 72-hour washout between each β€’ Pattern Report β€” ranked by how often each food appeared before your symptoms FEATURES β€’ 60+ foods in the built-in database β€’ Allowed vs avoiding foods filtered by your personal plan β€’ 8-symptom daily check-in with 0–5 severity β€’ Linked-meal timing β€” connect a symptom to the meal that came before β€’ AI pattern analysis (qualitative, never diagnostic) β€’ Local reminders for test days and washout completions β€’ No HealthKit, no tracking, no third-party ads CULPRIT PRO Unlock every trigger ranking in your pattern report, with a plain-language note for each food. Notes are written by AI when you allow it; otherwise fixed wording is used. β€’ Monthly β€” $7.99 β€’ Annual β€” $59.99 (save 37%) Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel in Apple ID Account Settings. IMPORTANT Culprit is a personal food and symptom tracker, not a medical device. It does not diagnose, cure, treat, or prevent any condition. Consult a healthcare professional for medical advice.
