Google Calendar: best for a mixed iPhone and Android couple
Google Calendar is free and works in a browser, on iPhone and on Android. You share a calendar by adding your partner's email, and you choose a permission level: free/busy only, see event details, make changes, or manage sharing. It is a general calendar, so tasks, spending and relationship check-ins live in other apps.

Apple Calendar: best for two iPhone users
Apple Calendar is already on your phones, and iCloud calendars can be shared. If one of you uses Android, you need a different tool.

TimeTree: best for a calendar-only group tool

Its Premium plan was listed at $4.49 per month or $44.99 per year, with ad-free calendars and file attachments.

Tandem: best when the calendar is part of shared life
Tandem: Couples Organizer is made for two paired partners. The calendar shows shared events and your partner's events, with colours, repeating events and reminders. You can also show events from your phone calendar to your partner (they see them read-only). The same app holds shared and private to-do lists, shared expenses with a "who owes who" balance, and a Weekly Sync. Widgets for iOS and Android show upcoming events.
Choose Tandem if: you want one app for two people. Look elsewhere if: you need to share a calendar with more than your partner, or you want a pure calendar with no other features.
See the shared calendar for couples feature page.
One shared calendar or two?
Keep your own calendars for work and personal plans. Add one shared calendar for things that involve both of you: dinners, travel, appointments, visits, bills due. If everything goes in the shared one, you will stop reading it.
Three rules before you start
- Who adds events? The person who learns about it adds it, right away.
- Colours. One colour per person and one for "us".
- Private time. Mark it as busy, with no details, so the other person can plan around it.
