Time/happiness diaries just got a lot easier: There’s now a Track Your Happiness app for the iPhone.  How does it work?

  1. Answer a few questions

    First we’ll ask you some questions for statistical purposes. This will
    take about 10 minutes.

  2. Track your happiness

    Using your iPhone, you’ll be notified by email or text message and asked
    to report how you are feeling and what you are doing. You decide when
    and how often you want to be notified.

  3. Your Happiness Report

    This report will show how your happiness varies depending on what you are
    doing, who you are with, where you are, what time of day it is, and a
    variety of other factors.

I’m still not sold, but if I do get an iPhone, this will be my first app to add.
