wow...I am so happy to read all of these comments! I just published Mood Pulse https://play.google.com/store/apps/details?id=moodpulse.com and I am thinking about taking the three moods (happy, just ok, sad) to nine choices. reading all of your comments makes me wonder if this is a good move considering that my initial goal was to have a very simple app to record the user's mood over time.
