This is how easy Moodflow works: Fill out a quick survey every day and gain insight into the WHAT and HOW it influences you over time. ◆ 1. Pick a rating for the day from 1 to 5. ◆ 2.

On the one hand, a Calendar will be filled with colors that reflect your emotional well-being. This will allow you to get an eagle-eye perspective on your life that you never had before. On the other hand, Moodflow comes with data-analyzing tools, that will help you find relationships between a plethora of different factors and your mood.
