When you’re new to a school or campus, your smartphone will be your new beat friend. Here are four kinds of apps to help you get started in the US.

1. Social media: 1. You can use Facebook to communicate with various groups or people that share a common interest. Apps like Snapchat are more for close friends. Instagram focuses on photos you share. Twitter limits you to 280 character per “tweet,” or post. 2.

2. Ride-sharing: Need a ride? 3. Then you will find out how far the nearest ride is to your location and how much it will cost to get where you want to go. The app is linked to your bank account, so you don’t have to worry about carrying cash.

3. Eating: Don’t want to get off the couch（沙发）or move away from your desk? Order from almost any nearby restaurant, pay online, and wait for a delivery driver to bring it to your front door through Grubhub, UberEats or DoorDash. 4.
