UNDERSTAND TIME AS A WHOLE Most calendars organize time into boxes. But time unfolds through rhythms and cycles. CircleTime is a visual calendar that reflects that reality. Plan your day, week, and month with a clear visual calendar that helps you understand time as a connected whole. 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. No tracking. No ads. Just clarity. INTEGRATIONS Works seamlessly with Apple Calendar, Apple Weather, HealthKit, and iCloud. Follow your schedule, your activity, and the natural cycles around you.
