A shared custody calendar that both parents trust
Most co-parenting conflict starts with calendar confusion. Who has the kids Thursday? Whose turn is the birthday? What time is the handoff? A single source of truth, owned by neither parent individually but visible to both, removes the most common trigger for arguments.
Must have: Custom custody patterns (50/50, 2-2-3, 5-2-2-5), automatic handoff alerts, holiday rotations, deviation logging.
In Two Paths: Built in. Plus GPS-verified handoffs so contested pickups are documented automatically.
DIY equivalent: Google Calendar works for very low-conflict situations. Falls apart fast when the schedule starts shifting.
