ThreeDay Calendar
Today, tomorrow, next day
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
ThreeDay Calendar is built around the next three days: today, tomorrow, and the day after tomorrow. Instead of opening a full month grid every time, you can scan what matters now in a simple 3-day timeline.
Key features
- See today, tomorrow, and the day after tomorrow at a glance
- Show events from calendars connected to your device, including iCloud, Google, Exchange, local, and shared calendars
- Create local events or save directly to writable device calendars
- Add title, start time, end time, repeat, location, reminder, and description
- Search titles and notes across local and device calendar events
- Hide calendars you do not need and rename calendar labels inside the app
- Use event templates for repeated forms of events
- Choose light, cream, or dark theme
- Premium: home screen widgets for today, tomorrow, the day after tomorrow, and event cards
- Premium: replace the ad area with a memo, photo frame, or D-Day display
Privacy and data
Your schedule data stays on your device. The app does not store your events on a separate server. Calendar access is used to show and write events through iOS device calendars when you allow it.
Note
Calendar sharing permissions are managed in Apple iCloud Calendar, Google Calendar, Exchange, or the calendar service you use; this app displays shared calendars that are already connected to your device.
