Is there an app for that?

I'm curious if anyone has found certain apps or tech toys helpful in caring for loved ones with medical problems like heart failure, COPD, and diabetes.

I myself use fitbit and the mapmywalk app to stay on top of my workouts, and it got me thinking -- there aren't that many apps for caregivers. At least that I'm aware of.

One of my friends makes iphone apps for a living and he asked me what my app "wishlist" is as a caregiver. The question got me thinking, so I thought I'd pass it along to everyone. What kinds of tech tools are you using now to make caregiving easier? What do you wish was out there?
