One overnight calendar for two homes.

FamSync is a free co-parenting app for separated parents, built around one question: where do the children sleep tonight?

The FamSync overnight calendar: each night colored by the parent who has the children

The heart of the app: the overnight calendar

Both parents open the same calendar and see the same nights. Everything else in FamSync starts from it.

  • Each night takes the color of the parent who has the children.
  • The app counts each parent's overnights.
  • Changes don't become arguments: one parent proposes a swap, the other accepts or declines.
  • Each family picks a mode: collaborative, where either parent edits and the other is notified, or protected, where agreed nights change only with the other parent's approval.
  • Notifications reach each parent in their own language.

Holiday Plan: December 1–31, 2026

The holidays are when the calendar matters most. Our in-app event opens it on Christmas Eve, so parents can settle Christmas Eve, Christmas Day and New Year's Eve night by night. The event art has no text, so the same images serve every language.
