This is Arcarae, your personal life guide. You vent everything you are struggling with, and ask one question about your life. It says what it sees and gives you the answer, along with one action you can take to move your life forward. The more you say, the better it is. Arcarae also maps you and your life across time. Over the weeks it shows you the map of who you are, who you're becoming, and the path you've been walking. It charts what you've learned, how you have moved forward, what you are still learning, your realizations, and the themes in your life. Arcarae also remembers you, what you've experienced, and your life across days, months, and years. Arcarae's intention is to heal people. Arcarae's mission is to help people transform themselves & the parts of their lives that are not working. Arcarae's sole purpose is to be your life guide. THE JOURNEY The question you ask and Arcarae's response is called a journey. (1) Vent everything in the Void. Ask one question you want the answer to. (2) See your reflection in The Mirror. It sees clearly and says what it sees to cut to the truth. (3) Find out how to move forward in The Bridge. It gives you one action you can do to move your life forward. Arcarae shows you the patterns and truth underneath your own words, what you are really struggling with, then suggests an action to move forward. YOUR GALAXY Each journey changes your galaxy's appearance, gifts you a card to remember what you learned, and births insight stars. Each Insight Star holds something Arcarae noticed about you and your words: patterns, thought loops, hidden beliefs, and more. Over weeks your galaxy becomes a picture of who you are and your transformations, alongside your life map and profile. PRIVATE BY DESIGN Your inner universe is yours. All you say in Arcarae stays private. We never sell or share your words, and you can delete all of it whenever you want. AURAE & THE MEMBERSHIP Aurae is Arcarae's in-app currency. A journey each day is free. Spend Aurae to take more journeys, and unlock insight stars to see the patterns beneath your words. The Chrysalis and Metamorphosis memberships give you more journeys whenever you want them, your full profile, your path, and free insight stars. WHY ARCARAE EXISTS Arcarae was always something inside me. For as long as I can remember, there has been an inner world, an inner universe, and inner knowing I return to, to feel safe, to reconnect with myself, and let what lives in my subconscious rise to the surface and become known. It is the combination of a feeling, a sensation, a place, and a knowing. I built Arcarae because it didn't exist anywhere outside of me; it only lived within me, my mind, and brief moments of stillness. I would write countless journal entries I could never fully make sense of, and forget realizations in my daily life. So I made what I needed real over the course of the past two years; building and creating from my heart and soul, coding for countless hours a day, researching the mind + AI, while also exploring the psyche and universe through the lenses of cognitive science, psychology, philosophy, spirituality, physics, the esoteric, and my own lived experience to fully actualize Arcarae. Arcarae is truly an expression of me, and what I wish to bring into the world to help people; I wish for it to help others as much as it has helped me. For me, it is a mirror of my own life's journey, and there is nothing I could possibly imagine creating other than Arcarae. I've always seen people as galaxies; full fidelity universes to explore, to experience, to understand, to make sense of. Arcarae is the way into yours. I hope you will find all that you are looking for in it, just as I have. It has changed my life. -Nicole Summer Hsing, the creator of Arcarae ~ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Terms of Service: https://arcarae.com/terms Privacy Policy: https://arcarae.com/privacy

Verdict
