Cardiology care is mostly what you do between visits. Patterns in heart rate, blood pressure and symptoms over weeks tell your cardiologist far more than a single reading in the office. Apple Health already records much of this; the trick is seeing it next to how you felt. Emerge Care, free to download on iPhone, is built for exactly that: tell it how you feel in your own words, get plain answers with the source behind every fact, and walk into your next cardiologist appointment in Pennsylvania with a one-page summary and your questions ready.
