Read full description

A calendar reflects what you do with your time. Existence shows what type of person your time is actually creating. Existence is a Time Intelligence Platform that turns your time into data, your data into understanding, and your understanding into a life more precisely aligned with the one you intend to create. It guides you through the Time Creation Cycle. Each week, you Design your time with intention, Account for what actually happened, and Optimize based on what your record reveals. Each cycle moves you closer to the person you intend to be. DISCOVER THE REAL YOU Most people believe they know how their time is spent, yet the gap between what they think they do and what they actually do is wider than most realize. The Ideal You is the person you know you're capable of being, and the Real You is the person your time actually creates. Existence makes the distance between them visible. DESIGN YOUR WEEK Life is created week by week. Time Blocks structure your week across Work, Life, Health, and Sleep pillars, setting intentions for what you'll do, when, where, and with whom. Each week, you design your time with intention, block by block, projecting the Ideal You forward in time. ACCOUNT FOR ALL OF YOUR TIME Most time goes unaccounted for, and what goes unaccounted for can't be understood, changed, or optimized. As each Time Block passes, update it to reflect what actually happened. Over time, Existence reveals the quality of your experiences and where your life is most out of alignment with your intentions. ACCOUNT FOR ALL OF YOUR TIME Most time goes unaccounted for, and what goes unaccounted for can't be understood, changed, or optimized. As each Time Block passes, update it to reflect what actually happened. Over time, Existence reveals the quality of your experiences and where your life is most out of alignment with your intentions. INPUT YOUR DATA WITH EASE Calendar imports, recurring blocks, and predictive tagging make the practice lightweight. The more you use Existence, the more it learns, automating your Time Blocks so each cycle runs faster than the last. CONSULT YOUR PERSONALIZED AI Existence AI provides targeted insights based on your time data. Ask it why your energy drops mid-week, which environments make you most focused, or how the way you spend your days compares to the life you said you wanted. The more time you account for, the sharper its guidance becomes. LEARN FROM THE DATA Your Time Alignment Score reveals how much of your time is accounted for, how closely your actions track your intentions, and where the gaps are. That clarity is what moves you closer to the Ideal You. With the data you provide, Existence turns your record into understanding. That understanding becomes the input for the following week’s Design. Each cycle gets clearer, each adjustment more precise. Over time, the Real You and the Ideal You move closer together. Existence closes the gap between who you are and who you intend to become. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
