CoParnt

Features
Read full description

CoParnt is the co-parenting app built around one idea: every change goes through both parents. Shared calendars are fine for keeping track โ€” but when plans change, a calendar entry doesn't tell the whole story. CoParnt adds an approval layer so neither parent is caught off guard. Request a schedule swap, explain why, and let your co-parent accept or decline. Everyone sees the same thing. No crossed wires. WHAT YOU CAN DO Shared Calendar See the full picture: which child is where, which parent has them tonight, and what's coming up this week. Add school events, appointments, sports, and activities โ€” linked to the children they involve, so nothing gets lost in a general family calendar. Handovers Log your regular custody schedule as recurring handovers, then add one-off changes on top. Each handover stores the time, location, and coordinates โ€” so getting directions to the drop-off spot is one tap away. Requests & Approvals Need to swap a drop-off time? Ask your co-parent โ€” with a reason, and a clear view of what's changing. They approve or decline. No ambiguity, no "I never agreed to that." Reminder Requests Ask your co-parent to handle something for the kids โ€” buy school shoes, pack the swim kit, return the library books. Reminders can recur on a schedule and track completion, so nothing falls through the cracks. Tonight at a Glance Open the app and immediately see which parent has the children tonight, any handovers for the day, and any requests waiting on your attention. Push Notifications Get notified when a new request comes in, and receive a morning summary of anything that still needs a response.
