When commuting home late at night, traveling on solo road trips, or walking across a university campus after dark, loved ones frequently ask: “Text me when you get home safely.” However, after long journeys or tiring shifts, people often forget to send that confirmation text, causing unnecessary worry for parents, partners, and friends.
To provide peace of mind and enhance personal safety, Apple introduced Check In natively into the Messages app on iPhone (iOS 17 and newer). Check In automatically detects when you arrive at your designated destination and sends an automated notification to your selected contact. If your journey stalls unexpectedly or you fail to respond to safety prompts, Check In securely shares your route, battery level, and cell signal with your trusted friend. This guide explains how to set up and use Check In on iPhone.
How Check In Protects You Technically
Check In utilizes your iPhone’s onboard sensors and location services:
- Automatic Arrival Detection: Once you enter your home or destination address boundary, your iPhone sends an instant, end-to-end encrypted notification confirming: “Arrived safely.”
- Delay Prompts: If you stop moving unexpectedly or your progress deviates significantly from your navigation route, your iPhone chimes and displays a 15-minute prompt asking if you are okay.
- Emergency Escalation: If you do not respond to the safety prompt within 15 minutes, Check In sends an alert to your contact containing your last known location, battery percentage, and cellular connectivity status.
Step-by-Step: Starting a Check In on iPhone
- Open the Messages app on your iPhone.
- Open the conversation with the family member or friend you want to notify.
- Tap the Plus (+) button to the left of the text input field.
- Tap More and select Check In.
- A yellow Check In widget appears in the message draft. Tap Edit on the widget to customize your settings:
- When I arrive (Destination Mode): Select your destination (e.g. Home, Work, or a friend’s address). Choose your transportation method (driving, transit, or walking). iPhone automatically estimates your arrival time and adds an arrival buffer.
- After a timer (Time Mode): Ideal if you are going for a 45-minute jog or meeting someone new. Set a countdown timer; if you do not cancel the timer before it expires, your contact is notified.
- Tap Done.
- Tap the blue Send arrow to initiate the Check In session.
Configuring Check In Data Sharing Levels
You can control how much personal diagnostic information your iPhone shares if you fail to check in:
- Open Settings on your iPhone.
- Scroll down and tap Messages.
- Tap Data under the Check In section.
- Choose between:
- Limited: Shares your current location, network signal, and battery level for your iPhone and Apple Watch.
- Full: Shares all Limited data plus your complete travelled route and the exact location where your iPhone was last unlocked.
Privacy and Security Safeguards
| Security Parameter | Check In Implementation | User Benefit |
|---|---|---|
| Encryption | End-to-end encrypted with Apple | Only your selected contact can view location data; Apple cannot read it |
| Arrival Automation | Stops automatically upon arrival | No need to remember to text or open your phone |
| Battery Warning | Alerts friend if battery dies | Prevents loved ones from panicking if your phone simply ran out of charge |
Adding Extra Time During Travel
If you encounter unexpected traffic delays or stop for petrol during your journey, swipe down your iPhone Lock Screen, tap the Check In alert, and select Add Time (adding 15 minutes or 1 hour) to prevent false alerts from triggering.
