User reviews

Loved it, then it wiped my info

I loved this MCAS tracker until I logged in today to see all of my information was wiped, the app had changed completely and no longer tracks the same way and it’s now not collecting the symptoms they way I need to. I liked the old version better but like the calendar and time update only. Please go back to the previous version but only keep the ability to edit the time and date.

Response from developer

Thank you for sharing this. We’re sorry your data appeared missing after the update. Originally, Mast Cell Tracker only stored data locally on device because we wanted to prioritize privacy and avoid sending health information to a server. After hearing this feedback, we developed optional account sync/backup so data can be saved and restored more reliably. We also restored fuller symptom tracking while keeping the calendar and editable date/time improvements. We appreciate the detailed feedback and used it to guide this update. If the new version better supports your tracking needs, we’d be grateful if you’d consider updating your review. As a nonprofit, thoughtful reviews help people find the app since we do not rely on advertising or marketing.

Glitch

I really want to use this app and promote it on all my MCAS Facebook groups if it’s good but I can’t get past the first page. It’s too large so I can’t see any next button. I select the top three things and then I’m stuck

Response from developer

Hi! Thank you so much for taking the time to leave this review and for your willingness to share MastCell Tracker with your MCAS Facebook groups — that truly means the world to us! We're so sorry to hear you're having trouble getting past the first page. We want to get this fixed for you as soon as possible! Could you help us out with a few details? - What phone model are you using? (e.g. iPhone 15, Samsung Galaxy S23, etc.) - What operating system/version? (e.g. iOS 17, Android 14) - What screen size or display settings do you have — do you use any accessibility settings like larger text or zoom? - Can you describe exactly what you see on the first page — is the "Next" button cut off, hidden below the screen, or just not visible at all? Your feedback is exactly the kind of thing that helps us make this app truly accessible and functional for the entire MCAS community. We are committed to resolving this and would love your help testing once we push a fix. Thank you again for caring enough to reach out!

A truly helpful app for managing MCAS

I’ve been waiting for an MCAS tracking app like this for a long time, and I’m so happy someone finally made one. MastCell Tracker makes it really easy to log flares, triggers, and symptoms in a simple, organized way. The design is clean and the data insights are actually helpful for understanding patterns over time. It’s great to finally have a tool built specifically with MCAS in mind.
