Events, reminders, tasks, weather, daylight, moon phases, and activity come together in one connected view. The circular view gives clarity at a glance. You see when the day begins, when light fades, when routines fit, and when rest comes. Less overwhelm, more focus. Discover patterns that traditional calendars often hide. Understand how your plans, movement, and natural rhythms fit together throughout the day. Instead of switching between apps, lists, and trackers, everything is organized in a single timeline that helps you stay focused, reduce overwhelm, and plan with greater clarity. FEATURES • See your entire day, week, and month at a glance • Never lose track of events, reminders, or tasks • Plan with daylight, weather, and lunar awareness • Understand when your activity happens, not just how much • Stay focused with a visual timeline that reduces overwhelm • Keep your schedule close with widgets and Apple Watch PRIVACY FIRST Your data stays private on your device.
