If you’re a Snapchat user on your iPhone, there’s a good chance you’ve been using the app to take pictures and videos. But if you want to delete the app, there are a few steps you need to take. First, open up the App Store on your iPhone and search for “delete Snapchat.” Once you find it, tap on it and follow the instructions. Once you’ve deleted the app, be sure to close it out of your App Store account so that future updates won’t overwrite your data.
