GutLedger

GutLedger is a mobile application designed for individuals managing IBS and those following a FODMAP diet, with a focus on privacy and data control. The app operates without requiring an account, does not send data to the cloud, and stores all information locally on the device. It is available for download on both the App Store and Google Play. The core functionality is free, while Pro features can be unlocked through a one-time purchase.

The app provides a comprehensive suite of tracking tools, allowing users to log meals, drinks, symptoms, mood, stress, stool, sleep quality, fluid intake, medications, and menstrual cycle details. Its food and drink diary enables users to record meals with descriptions, photos, and notes, while a built-in database of over 470 foods automatically tags items as low, moderate, or high FODMAP. Drinks are tracked separately to help identify potential triggers, and barcode scanning with offline caching is available as a Pro feature. Smart suggestions and trigger warnings assist in identifying problematic foods, and meal ingredient breakdowns are provided for more precise tracking.

Symptom tracking covers more than ten symptom types with severity and duration ratings, while mood and stress can be rated on a five-point scale. The app also supports period tracking, allowing users to correlate hormonal changes with IBS symptoms. Stool logs use the Bristol Stool Scale and include urgency tracking, with the option to attach private, blurred photos for medical consultations (a Pro feature). Sleep quality and fluid intake are tracked with customizable goals and progress indicators.

GutLedger includes a structured FODMAP elimination diet guide, following a three-phase protocol with guided reintroduction challenges and personalized tolerance tracking. Medication logging allows users to correlate treatments with symptom patterns. A daily gut score, calculated from recent symptom severity, sleep quality, stress, and hydration, offers a composite measure of gut health. Meal planning features help users build weekly meal plans and log entire days’ eating with one tap, supporting adherence to a low-FODMAP routine.

The app also integrates with sister applications, ListLedger and Settle, enabling users to share detected trigger foods directly to shopping lists or recipe planners on their device. All interactions remain device-to-device, maintaining the app’s privacy-first approach.
