Culprit
Read full descriptionHide full description
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 0β5 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.

Verdict
The clearest difference is in-app purchases: Poop Tracker at none against Culprit's 2. Poop Tracker also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). Culprit's advantage is ads (none vs shown). On price there is nothing between them.
