OT - What's your favorite app?

What are some of your favorite apps that you use every day or almost every day? Inspirational, productive, business, health, etc..I know there are good ones out there, but when I'm searching I usually end up downloading apps that I delete shortly after.

I read in a Crohns magazine, while waiting to see my GI, that there are some great new apps out there for us with GI issues.

Some of these are: gps bathroom locators, stool trackers, diet trackers, specialty diet apps, and really common these days symptom trackers (ie. web MD)

I forgot to look into these until I seen this thread. Technology...gotta love it :)
