Show HN: Toutday for iPhone, simpler mood tracking

Toutday (pronounced "too-day" -- names are hard) is an iPhone app designed to make it easier to keep track of daily mood trends. The interface revolves around answering a simple question, "How was your day?", once a day.

More fine-grained data entry is available once an overall mood is selected, including qualitative weather reporting, socialization, and a daily journal.

Any feedback would be greatly appreciated, as this is my first app launch.
