"While the app enables health plans to deliver Warm Health’s care management programs, its distinguishing feature is a live chat channel, called Warm Chat, that enables health plan staff members, like those on a care management team, to have real-time conversations with their members. The app also offers a mood tracking journal, called Warmth Factor Journal."
Just one more small (?) example of how technology is transforming health care. No, I don't know what the "mood tracking" is about.
