BellyMystery helps you notice patterns between what you eat and how you feel, without slowing down your day. Log a meal in under 30 seconds with a photo, and BellyMystery identifies the likely ingredients for you. Log a symptom or a stool entry (Bristol scale) in under 15 seconds. Add a quick note about illness, medication, or travel so those get factored in too. Behind the scenes, BellyMystery's statistical engine looks for correlations between what you've logged, entirely on your device. When it finds something worth a second look, an AI-generated summary explains it in plain language, and always frames it as a pattern worth discussing with your doctor. BellyMystery never diagnoses you. When you're ready to talk to a doctor, export a clean PDF summary of your patterns and full diary directly from the app to share however you like. Why BellyMystery: Fast logging: meals, symptoms, and stools take seconds, not minutes. Works offline: logging never waits on the network. Photos are analyzed when you're back online. Private by design: no account, no login. Your diary lives on your device. Only a meal photo (to identify ingredients) and a computed summary of your patterns (to generate narration) are ever sent off-device, and neither is stored afterward. No ads, no trackers, no data brokers. BellyMystery includes a short free trial. After that, a single one-time purchase unlocks the app for life. No subscriptions. BellyMystery is not a medical device and does not diagnose, treat, or cure any condition. It's a tool for noticing patterns in your own data to discuss with a healthcare professional.

  • This app hasn’t received enough ratings or reviews to display an overview.

Redesigned doctor report. The PDF now has a clearer overview: how many days you logged, your stool types on the Bristol scale, a summary of each symptom with how often it happened and how bad it got, and your daily water intake. One simple file to share. The report is now a single PDF, so it attaches cleanly to any email or messaging app. Smarter meal reminders. If you've logged a meal in the last two hours, the next reminder is skipped. No more nudges right after you've eaten. Better practitioner directory. Filter by country and then by state, search for individual dietitians inside a practice by name, and see each team member's photo and role. Faster meal photo recognition. Ingredients from your photos come back quicker.
