Checkly — Calendar Checklist

Your calendar and to-do list, finally in one place. Check off events like tasks — and get an urgent nudge if anything slips past its deadline.

Checkly turns your calendar into a checklist. Create events with your preferred reminder times applied automatically, mark them as to-dos, and check them off as you go.

• To-do events — check them off like a checklist. Completed items sync as DONE across all your devices' calendars. • Overdue warnings — unfinished to-dos stay on your list with a red warning and fire an urgent notification at their end time. • Automatic reminders — set your default notification times once (5 min, 30 min, 1 day before…) and every new event gets them. • Full event details — tap any event to view or edit title, dates, notes, and calendar. • Works with your existing calendars — iCloud, Google, and anything else in the Calendar app. Changes made elsewhere appear automatically.
