DayBay: Shared Calendar
Productivity
Free
DayBay is a shared calendar for couples, families, and the people closest to you.
See everyone's plans in a clear monthly calendar, leave a note for a specific day, and keep everyday tasks such as shopping, chores, and things to bring in a shared to-do list. Personal and shared calendars are kept separate, so private information stays private.
Key features:
- Personal and shared calendars
- Notes for each day
- Shared to-dos and completion history
- Repeating events
- Event reminders and iPhone alarms
- Add multiple events at once
- Import from Google Calendar, Outlook, and device calendars
- Export events as ICS, and to-dos and notes as CSV
- Shared update history and emoji reactions
- Home Screen widgets
External calendar events are copied only when you select them. DayBay does not continuously sync with or write changes back to external calendars.
