Keep the plan going between appointments

Most of internal medicine happens between appointments: a routine to keep, a symptom to watch, labs to repeat. Writing down how you feel each day turns a vague "it has been fine, I think" into a clear picture at your next check-up. 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 internal medicine doctor appointment with Dr. Heiselman with a one-page summary and your questions ready.
