iOS: Happiness seems like a simple enough emotion, but it can actually be a pretty complex concept.

Track Your Happiness aims to understand happiness a little better by analyzing yours.

The app is actually part of a research project, launched by Harvard researcher Matt Killingsworth.

Its more than just atraditional mood tracker; its more like a moodanalyzer.

The aim of the app (and the project) is to better understand what causes your own happiness.

To use the app, sign up with your email address.
