A complete iPhone calendar

The app shows the work instead of describing it.

Every core calendar screen shown here was captured from the current iPhone build with one consistent set of fictional sample data.

InstaCal Agenda on iPhone with events, reminders, weather and a Join button
Agenda

The entire day in one continuous view.

A mini month gives the date context; the agenda puts events, invitations and Apple Reminders in the order they happen.

  • Weather and moon information stay attached to the day
  • Live countdowns show exactly how close the next event is
  • Join Zoom, Meet, Teams, Webex and more without hunting for a link
InstaCal Reminders view on iPhone
Apple Reminders

Tasks belong beside the time they affect.

See due reminders alongside events, or open the focused Reminders view when the list itself needs attention.

  • Due time, list, notes and priority remain intact
  • Complete reminders from the agenda or an interactive widget
  • Create and edit reminders without switching apps
InstaCal Month view on iPhone with weather and event bars
Month

The month stays readable on a phone.

Event bars, weather and moon phases stay in the calendar grid, so the shape of a busy month is visible before you open a day.

  • Colored event bars preserve calendar context
  • Weather and moon information remain attached to each date
  • Tap any day to move directly into its schedule
InstaCal Month view on iPhone in dark mode with weather, moon phases and event bars
Dark mode

Every view is at home after dark.

InstaCal follows your iPhone appearance across the calendar, controls and event details while preserving useful color and contrast.

  • A true black calendar background feels natural on OLED displays
  • Event colors, weather and moon phases stay distinct at a glance
  • The same complete Month view, without a stripped-down night layout
Six views built for touch

Move from the next hour to the next three months.

Agenda, Day, Week, Month, Quarter and Year are separate native views — not one phone layout stretched into different shapes.
