If you’re a Snapchat user on an iPhone, there’s a good chance that you’ve been using the app for years without realizing it. But if you’re like most people, you may have to update the app to keep it running smoothly. Here’s how to do it:

  1. Open the App Store on your iPhone and search for “Snapchat.”
  2. Tap on the “Update” button at the top of the screen.
  3. Type in your Snapchat username and password and hit “update.”
  4. The app will ask if you want to continue using Snapchat or update to a newer version. Choose “update” and follow the prompts to complete the process.
