Tolera

Tolera helps people following a low-FODMAP plan keep meals, symptoms, protocol steps, and Apple Health context organized in one private app.

It is designed for people working with a doctor, dietitian, or other healthcare professional who want a clearer way to record what they eat, how they feel, and where they are in a structured low-FODMAP process.

THREE-PHASE LOW-FODMAP ORGANIZATION
Tolera gives you a place to track the phases commonly used in low-FODMAP care:
* Elimination - record meals and symptoms during your initial low-FODMAP period
* Reintroduction - organize food challenges by FODMAP subgroup
* Personalization - keep notes as you review possible tolerance patterns over time

FODMAP STACKING VIEW
Track daily intake estimates across six FODMAP subgroups: excess fructose, lactose, fructans, GOS, sorbitol, and mannitol. The budget view helps you see how logged foods may add up across a day.

SIX WAYS TO LOG MEALS
* Snap a photo - AI-assisted food and portion entry
* Pick from your library - analyze an existing meal photo
* Scan a barcode - look up packaged foods using Open Food Facts and USDA data
* Voice - describe your meal, with on-device transcription preferred when available
* Recipe URL - import details from a recipe page
* Manual - search 429 foods with FODMAP estimates and subgroup details

PATTERN REVIEW
Tolera can help you review possible relationships between meals, symptoms, protocol phase, and optional Apple Health context such as sleep, HRV, exercise, and cycle data. Results depend on the information you enter and should be interpreted with your healthcare professional.

PRIVACY BY DESIGN
* No account required
* Your meals, symptoms, and protocol data stay on this device in the current release
* Cross-device sync is not available in this version
* HealthKit data is read on-device only, never transmitted

WHO IT'S FOR
Tolera is built for people who:
* Have been advised by a doctor or dietitian to try a low-FODMAP diet
* Want a structured place to log meals, symptoms, and protocol progress
* Want to review possible patterns from their own entries over time

Tolera is not a substitute for medical advice, diagnosis, or treatment. Talk to your healthcare provider before starting any elimination diet, especially if you have other dietary restrictions or health conditions.
