| What needs to be coordinated | Justoo is focused on a shared view of co-parent hand-offs. | A shared calendar is a general way to view appointments, events, and recurring plans. | Choose a hand-off workflow when the exchange itself needs a shared state; choose a calendar when schedule visibility is the main need. |

| Handoff state versus event time | The product description refers to whether a drop-off is unstarted or unconfirmed. | A calendar event communicates timing but may be enough when no separate hand-off state is needed. | Decide whether a time on a calendar answers the question your family is actually trying to resolve. |
|---|
| Private family data model | The current store summary says the shared information is stored in each family's own encrypted iClouds. | Other calendar products have their own account, sharing, retention, and privacy models. | Read the current privacy and sharing terms for the exact product you choose before putting sensitive family information in it. |

| Notification meaning | A support signal about an unstarted or unconfirmed hand-off is coordination information. | A calendar reminder is a scheduling prompt. | Neither signal verifies arrival, location, safety, consent, or what happened in the real world. |
|---|
| Records and disputes | A coordination tool can help a family stay aligned on its own process. | A calendar can preserve planned events for ordinary planning. | Use the records and professional support required by any agreement, court, school, or local rule; do not assume an app creates an official record. |
