Add a widget
On Mac, right-click the desktop and choose Edit Widgets. On iPhone or iPad, touch and hold the Home Screen, choose Add, search for InstaCal and select a size.

Widget choices
InstaCal’s nine designs are Next Event, Now + Next, Days Ahead, Week Map, Reminders, Today, Month, Up Next + Calendar and Countdowns. Available sizes vary by platform.
Month and Week layouts draw multi-day events as continuous bars. Agenda and reminder widgets keep date-only reminders as Anytime and leave due reminders visible until completed.
Countdowns can follow a calendar event or a standalone important date. Small and accessory families focus on one moment; larger families add more of the upcoming lineup. See Countdowns and Important Dates for setup.
Configure a widget
Long-press or right-click the widget and choose Edit Widget. Depending on the design, choose calendars or a Calendar Set, event and reminder visibility, list placement, size-specific density and theme.
Up Next + Calendar adds two per-widget controls. Privacy can show Full Details, Times Only or Busy Only, and Show Weather can keep forecast context on one placement while hiding it on another. These choices affect only that widget.
Countdowns lets each placement use Smart Upcoming or pin one saved Featured Date. Removing a pinned date safely returns that instance to Smart Upcoming.
Mac widgets can use System, Light or Dark independently of the Mac appearance so they remain legible on the wallpaper.
Act from a widget
Select an event to open it in InstaCal. Interactive reminder widgets can complete a task in place; tapping again during the undo period restores it.
Refresh and stale data
Widgets read a small shared snapshot instead of opening the calendar database on every refresh. If that snapshot is too old, the widget marks itself Out of Date rather than presenting stale information as current. Open InstaCal to refresh the shared data.
