Constellation

Constellation helps you track their dreams, allowing you to discover more about yourself. 

This app is designed to do more than a standard journal by categorizing the information of each dream. The tag feature allows for easy sorting, this can be used for comparing dreams of a similar type (e.g. someone looks through all their nightmares to find a repeating theme). The analysis box being separate allows people to come back later and re-analyze their dreams with a new perspective. 

Dreams have been proven to hold a lot of information that can't be accessed by the conscious mind, which this app will utilize to help you learn more about your unconcious mind.  Learning about their unconscious mind will also help you understand your emotions instead of simply reacting to them.
