Mood tracking

There are a lot of mood tracking apps out there and most are free, but I have yet to find one as easy to use and well-designed as Moodnotes ($4.99, iPhone). You can customize to the app to check in with you as many times a day as you want, and your level of participation can be as little as adjusting a smiley face from frowning to grinning, to journaling and learning about common “thinking traps” and practices to avoid them. It also provides insights/stats about your moods over time. — CD
