Do you use the apps in your smartphone everyday? We know smartphone apps have many useful functions（功能）. Here are two apps.
Warning: Earthquake is coming!
A new app called EAS（Earthquake Alert System） gives users all the first— hand information about earthquakes around the world. It also provides a guide for self— rescue（自救）in case an earthquake happens near you.
But the best part of the app is that you can turn on its alarm system（警报系统） before you go to sleep. If an earthquake happens during the night, you'll be woken up by your phone and have a chance to get to safety
You can buy this app on Apple's app store for only 2 yuan per month, which seems a small price to pay to protect your life. But It's a pity that it can't be used on Android phones, such as Samsung phones and Huawei phones.

Snail Sleep — An app that improves your sleep, spends the night with you and helps you develop a good sleeping habit. It records your sleep information and gives a report to help you learn more about your sleep.
