MCAS is notoriously hard to see in a fifteen-minute visit. MastCell Tracker gives you continuous, longitudinal data and clinician-ready reports — so you can act on evidence, not just recall.
Continuous MCAS data, made for care teams.
Continuous biosignals and structured symptom logs reveal trends no single visit can capture.
Months of data distilled into a clean, shareable summary your patient brings to the appointment.
Trigger correlations and baselines help you reach targeted decisions faster — and spare patients years of guesswork.
Signals are validated against reference measures; patient data is encrypted, consented, and never sold.
We're a nonprofit working alongside clinicians, clinics, and researchers to make MCAS visible and care accessible. Whether you want to refer a patient, receive their reports, or explore a study, we'd love to talk.
It gives you objective, longitudinal data between visits — symptom trends, trigger correlations, and continuous biosignals from the MCT-1 — summarized into clinician-ready reports so appointments start with evidence instead of recall.
The MCT-1 and its algorithms are validated against reference measures, and we continuously monitor accuracy. See our Research page for the science behind the signals.
Patients export a clean summary report from the app and share it with you directly. No new system to log into — the data comes to the appointment.
We work with clinicians, clinics, and researchers on referrals, data-sharing, and studies. Reach out at Detailingformcas@gmail.com to start a conversation.
