During this stage you may need to update watchOS or iOS; follow on‑screen prompts and keep the devices near each other until syncing completes.
Step 3 – Sign in with Your Apple ID and Create a Passcode
You’ll be prompted to sign in with your Apple ID. This step ensures access to iCloud services, app purchases and Activation Lock. Next, create a passcode on your watch.

Medications, Mindfulness and Cycle Tracking
The Medications app helps track medications, vitamins and supplements. Add your medications to the Health app on your iPhone and log them on Apple Watch. The Mindfulness app lets you log your state of mind and encourages mindful breathing; open Mindfulness, tap State of Mind and record your moodsupport.apple.com. For users who menstruate, the Cycle Tracking app allows logging of periods and symptoms and uses heart‑rate data and wrist temperature to predict fertile windows. Keep in mind that retrospective ovulation estimates may be unavailable in some regions.
Vitals and Health Status
watchOS 10 introduced the Vitals app, which displays overnight metrics such as heart rate, respiratory rate, wrist temperature, blood oxygen and sleep duration. When you wear your watch to bed, the app establishes a typical range for each metric. If multiple metrics fall outside your typical range, you receive a notification with context like medication changes or illness. Some models sold in the United States after January 2024 have blood‑oxygen measurements disabledsupport.apple.com.

Setting Up Safety Features
Medical ID
A Medical ID stores critical health information (allergies, conditions, medications) and emergency contacts. Set up your Medical ID in the iPhone Health app; details automatically sync to your Apple Watchsupport.apple.com. To view your Medical ID on the watch, press and hold the side button until the sliders appear, then slide the Medical ID slider to the right. You can also open Settings > SOS > Medical ID on the watchsupport.apple.com.
Emergency SOS
Emergency SOS lets you call local emergency services and alert your emergency contacts. When you make a call with Emergency SOS, your watch automatically dials the local emergency number and shares your location with responderssupport.apple.com. After the call ends, the watch sends your contacts a text message with your location and continues to update them for a period of time. To call emergency services, press and hold the side button until the Emergency Call slider appears; on Apple Watch Ultra models you can press the Action buttonsupport.apple.com. You can drag the Emergency Call slider to start the call immediately or keep holding the side button until a countdown finishes. Crash Detection and Fall Detection can also automatically call emergency services on supported models. If you accidentally start a call, release the button to cancel the countdown or, if the call has connected, inform the responder and cancel the text notification.
Optimize Emergency SOS Settings
To prevent accidental calls, open the Watch app on your iPhone, tap My Watch > Emergency SOS and turn off Hold Side Button to Dialsupport.apple.com. You can still use the Emergency Call slider when needed. International emergency calling is supported on Apple Watch Series 5 and later (GPS + Cellular) and Apple Watch SE or Ultra models; when traveling abroad the watch calls the local emergency services but may not send your location or text message.
Setting Up Apple Pay
Apple Pay on your watch lets you pay with a double‑click of the side button. To add cards, open the Watch app > Wallet & Apple Pay > Add Card; follow prompts to add credit or debit cards, store cards or transit cardssupport.apple.com. Alternatively, open the Wallet app on your watch, tap More Options (•••) and Add Card. You can set a default card and reorder multiple cards by tapping Edit and dragging the three‑line handle. If you need to remove a card, swipe left on it and tap Delete.
Real‑world example: Suppose you’re at a coffee shop and your hands are full. Rather than fumble for your wallet, double‑click the side button on your watch and hold it near the payment terminal. The watch vibrates to confirm the transaction. Because you set up a passcode earlier, Apple Pay remains secure even if your watch is stolen.
Real‑World Examples of Apple Watch Use
Fitness and Health Monitoring
Sarah, a 35‑year‑old marketing manager, used the Activity app to reach her Move goal of 500 calories per day. She adjusted her goals after an ankle injury and used the Workout app to track low‑impact yoga sessions. Thanks to sleep tracking, she realised she was sleeping only 6 hours a night; by adjusting her bedtime, her sleep score improved and she reported feeling more energised.
Safety Success Story
While hiking, James tripped and suffered a hard fall. His Fall Detection (on Apple Watch Series 8) detected the impact and displayed a slider to call emergency services. When he didn’t respond, the watch automatically dialed emergency services and sent his location to his wife. Within minutes, help arrived. This feature can be lifesaving, particularly for athletes and older users.
Productivity and Connectivity
Linda uses her Apple Watch to manage meetings and messages. She asks Siri to “Send a message to Alex: I’m running five minutes late,” using voice dictation and a quick check of the Smart Stack widgets for upcoming appointments. She also uses Apple Pay to board public transit. When her watch battery dips, she opens Control Center to enable Low Power Mode.
Additional Tips and Ongoing Maintenance
