Use Check In in Messages with a trusted person who agrees to receive it. Choose an arrival-based journey or a timer. If you do not complete the check and respond to prompts, the data shared depends on your choice: Limited includes current location, network signal and battery details; Full adds the route and device-use details. Compatible iOS versions are required, and a notification is not a safety certificate.

Choose a journey or a timer
Apple describes two modes. When I Arrive uses a destination and travel method; it completes when the iPhone arrives, and lack of progress or an unexpected arrival delay can trigger prompts. After a timer suits a period such as meeting someone new. If you do not end the check or respond as expected, the chosen details can be sent to your recipient. Choose the mode for your own plan, not to monitor the person you meet. [Apple iPhone Guide: Check In]
Read Limited and Full before sending
Limited shares your current location and the network signal and battery details of your iPhone and Apple Watch. Full includes that information plus the route traveled and the last time you unlocked your iPhone or removed your Apple Watch. These are the details available if the check is not completed as expected. Limited does not mean only a destination or a time. Review the choice with your trusted recipient before starting.

Plan for changes and connection limits
Apple provides ways to add time or cancel an active Check In. If the iPhone loses service or powers off, the recipient may receive an early or delayed notification and may be able to view the information you chose to share. Both participants need compatible iOS versions. Agree what a recipient should do if a notice is confusing; do not treat a notice as proof of danger or safety. [Apple iPhone Guide: Check In]
Agree on the human follow-up
Before the date, tell your trusted person the venue and planned time in an ordinary message. Explain whether the Check In covers the journey or a timed period and agree how they should try to reach you if needed. If the feature is unavailable, use a mutually agreed message or call plan. Keep your own transport and ability to leave. These are planning suggestions, not a guarantee that any app or contact will respond in time.
- Choose someone you already trust and who expects the check.
- Review the actual data choice on your own device.
- Explain a changed venue or time directly, as well as updating the feature.
- Keep a plain-message fallback.
A couple more questions
Should I send a first-date Check In to the person I am meeting?
No. Check In is a travel update for someone you already trust, not a way to monitor the date. Send it to a friend or family member and keep the date itself a normal social interaction.
What happens if my phone loses power during a timer Check In?
Apple says the recipient may receive an early or delayed notification and may be able to view the details you selected. Agree a follow-up plan beforehand rather than inferring an outcome from notification timing.
Can a Check In tell my trusted person that I am safe?
No. It concerns the iPhone’s arrival or your response to prompts, with data shared according to the selected setting. It does not certify personal safety.
Does the recipient need a newer iPhone too?
Check In requires compatible iOS versions on both devices. If the recipient's device is not compatible, use a simple agreed message instead and confirm the plan before the date.
