Read full description

Mind Flow Sketch is an app you can play with your mind. Thinking is breathing with your body and mind, always. When you inhale, feelings start circulating throughout your body. When you exhale, words are evoked from your mind, like tiny foams bubbling up from the deep deep water and scattering away to vanish... Yet, your thoughts will never vanish. Thinking keeps fermenting and maturing. And, one day, by an unexpected way or timing, your thoughts reconnect with your mind and new feelings and words are triggered, consciously or subconsciously. That is the beauty of human thinking: There exists "a sense of appreciating the serendipity", which today's machines cannot enjoy. Like drawing a sketch, write down words bubbling up from your mind. Take a moment to savour your thoughts. Let your mind be playful. NOTE: Daily journal, morning pages, new ideas....write anything you want, anything you feel. You can tag the note with themes. VIEW: Timeline: Daily view of your notes. You can enjoy the current of your thoughts flowing in your mind. Themes in the sky: Let's dive into the clouds of your thinking and enjoy the bird-eye view of what has been on your mind (themes you have created). PLAY: Yin-Yang: Yin-Yang (ι™°ι™½) is a conceptual system of two opposite, but interconnected elements. Choose your yin-yang themes and see how your thoughts are associated. You may discover hidden, subconscious connections or even a fresh perspective of your thoughts. Mind-Haiku: Haiku (δΏ³ε₯) is a Japanese style of poem, which consists of three lines. Because of this simplicity of style, Haiku gives us so much freedom or space for your imagination and inspiration between the words. Mind Flow Sketch creates a Haiku poem with the words you have spun. Enjoy the Haiku by your mind poet.
