Even when unexpected commitments throw off today’s plan, you don’t have to put your bigger goals on hold. Chrono Spark is an AI planner that helps you rethink your next steps when life disrupts your plans. For your bigger goals, AI creates a first draft of your monthly and weekly tasks. Keep a clear focus for the week, then adjust how you move forward when unexpected things come up. WHAT YOU CAN DO WITH CHRONO SPARK START WITH A MONTHLY AND WEEKLY PLAN Enter your goal and deadline, and AI creates a first draft of your monthly and weekly tasks. When getting started feels overwhelming, you can clarify what to work on first. KEEP MOVING, EVEN WHEN TODAY DOESN’T GO AS PLANNED Chrono Spark does not automatically assign daily tasks. When work, family, or another unexpected commitment gets in the way, a missed day doesn’t have to stop your entire goal. Reconsider what matters most for the rest of the week and keep moving forward. TALK TO AI WHEN YOU’RE UNSURE Not sure where to start today or how to approach this week’s tasks? Talk it through with AI Coach or AI Talk. Based on your tasks for the week, get help identifying what you can realistically work on today. ANOTHER REASON TO ENJOY A LONG-TERM GOAL As you complete tasks, a 50-episode story gradually unfolds, following its protagonists across all 47 prefectures of Japan. You are not the one taking the journey—the story is something to enjoy alongside your own long-term goals. FOCUS AND TRACK YOUR PROGRESS IN ONE PLACE Use the Pomodoro timer and tracking features to support the time you spend working toward your goals. WHO IT’S FOR • People with a big goal who get stuck when making the first plan • People who give up on the whole week when a daily schedule falls apart • People who want to organize what matters this week while adapting to each day • People working independently on certifications, creative projects, personal development, or reskilling • People who want a little story and enjoyment alongside their goals Make room for the unexpected without losing sight of what matters this week. Build a better way forward for your bigger goals with Chrono Spark. [Terms of Use (EULA)] https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
