The iPhone has an emergency SOS feature for when you're in a dangerous situation and need help ASAP.
For iPhone X or the iPhone 8 models, press and hold the side power button and one of the volume buttons until the SOS appears. Drag the SOS button to the side and the local authorities will be dispatched to your GPS location.
For iPhone 7 or earlier, press the side power button 5 times, rapidly. The SOS logo will appear. Drag to dispatch help.
You can also program other emergency contacts through the Apple Health app already on your phone. These contacts can show up on the screen, as well, and you can call them for help if desired.
If you bring up the SOS and need to cancel, there is a cancel button at the bottom.

The iPhone has a secret mode which locks the user into a single application. You can use it whenever you hand your phone to one of your kids to ensure that they stay in the game or video that you are letting them see without allowing them to get into other apps.
