User reviews

Very useful

Setting up MCAS Tracker was quick and straightforward, and I was logging symptoms, meals, and medications within minutes. The trigger correlation feature has been the most helpful for me because it helped me notice that certain high histamine foods and stressful days were often followed by flushing and headaches. I use the app daily to track different symptoms like skin reactions, digestive issues, fatigue, sleep, and medication responses, and the reports make it much easier to understand patterns over time.

App review

I just want to say I’m really mind blown about this app already, and I just got started. They say health is wealth, which it true and very important. I have a feeling I’m going to have a great time with this app. Amazing job developers.

Response from developer

That kind of energy right out of the gate is always great to hear. You are absolutely right that health is wealth, and the real value kicks in once you start building a consistent habit with your symptom tracking and daily logs. After a couple of weeks of check-ins, the patterns and correlations start to surface, and that is where things get really interesting. Enjoy the journey, and welcome aboard.

Needs Improvement

The tracker keeps deleting my information. I have completed my profile at least five times now. It’s deleted again. Also it keeps deleting the medications in the medication tab.

Response from developer

This isn't expected behavior, and we'd want to look into your specific account to understand what's happening. Updating to the latest version from the App Store often resolves sync-related issues with older builds. If your tracking data still isn't holding after updating, reach out to us directly so we can take a closer look.
