MastCell Tracker

MastCell Tracker is a simple, supportive tool designed to help individuals living with Mast Cell Activation Syndrome (MCAS) better understand their symptoms, triggers, and daily patterns.
This app does not provide medical advice — instead, it offers an organized, user-friendly way to record how you feel and identify trends that you can later share with your healthcare provider.

Key Features

• Symptom Tracking
Log daily MCAS symptoms such as flushing, headaches, dizziness, fatigue, pain, itching, hives, and more.

• Trigger Logging
Record possible triggers including foods, environmental changes, stress, activity, medications, or exposures.

• Medication & Treatment Notes
Easily track what you’ve taken, when, and how you responded. This helps you understand what may be helping or worsening flares.

• Daily Diary
Write notes about how you feel each day — energy levels, flare-ups, lifestyle factors, sleep quality, and anything else you want to remember.

• Trends & Insights
View past logs to identify patterns over time, helping you understand your own MCAS journey.

• Clean and Simple Design
Built for ease of use so you can focus on your health, not complicated menus.
