The MastCell Tracker app is here — free on iOS and Android, and built hand-in-hand with the MCAS community.
Everything in one place
Living with MCAS often means scattered notes, half-remembered triggers, and appointments where it's hard to explain what a month actually felt like. The app brings it together: fast symptom logging, trigger identification, medication tracking, and AI-driven patterns you can share with your care team.
Works on its own — better with the MCT - 1
You can start today with manual tracking, no hardware required. When you're ready, pairing the MCT - 1 makes it effortless, filling your timeline automatically with continuous data.
