Imagine your phone is like a smart friend who watches you every day. If it sees that you're staying up late, taking naps during the day, or not moving as much as usual, it might guess that you're tired and tell you to go to sleep. It uses little helpers inside, like sensors in your phone and watch, to learn about your habits and know when to suggest a good night's rest.
Examples
- You take a long nap during the day, so your phone tells you it's time for sleep later.
- Your phone notices that you move very little in the morning, like after a big party, and offers you a nap.
