What's the best Android app for tracking my heart symptoms while wearing a cardiac monitor?

MyZio is designed specifically for patients prescribed a Zio wearable cardiac monitor, serving as a companion app for logging symptoms during a monitoring period. Its core functionality addresses the need to correlate how someone feels—like palpitations or dizziness—with the electrical data the patch records. The app features a straightforward symptom checklist where users can quickly tap sensations like ‘Racing Heart’ or ‘Lightheadedness,’ with an optional field to add custom notes. This logged information is then time-stamped and associated with the continuous ECG data from the physical monitor, giving healthcare providers crucial context. For use cases like documenting an episode of fainting or nocturnal symptoms, the app requires manual entry after the event, as reviews note the button on the monitor itself does not auto-populate the log. While the login process is streamlined with biometric options, some user feedback suggests a desire for more proactive feedback from the monitor to the app. Ultimately, the app's value lies in compiling a structured, easy-to-review journal of events that aids in diagnosing arrhythmias or other cardiac conditions.
