DualFlow is an application designed to help you easily discern and organize conversations with your unconscious mind and the archetypes within it. Inspired by the meditative practices developed by pioneers of Analytical Psychology like Carl Jung, DualFlow facilitates a mindful dialogue between your conscious ego and your unconscious. This is not about multiple personality disorder or anything of that nature. Rather, itβs a meditative act that allows you to explore the duality within yourself. During a session, you can seamlessly swipe between personas to switch perspectives without losing track of your conversation, experiencing the flow between your ego and unconscious mind.
