Summit Day Planner syncs with all of your calendars and creates a simple to-do list out of them automatically. It's also a powerful task manager, so you can plan everything in one place. You can drag & drop to reschedule (even multiple tasks/events at the same time), swipe to mark events complete, add checklists to appointments, see everything you've completed by day, prioritize tasks/events with a single tap and focus on the next step toward achieving your goals.
