What is snapchat added by phone?

Snapchat is a mobile messaging and multimedia application that allows users to send and receive photos and videos that disappear after being viewed. The app was first created in 2011 and has since grown in popularity, reaching over 500 million active users each month. One of the app's unique features is the addition of augmented reality filters that can be applied to photos and videos, adding animations and interactive elements. Snapchat also offers chat and messaging features, including voice and video calls. The app is available for free on both iOS and Android devices. Users can create a Snapchat account by downloading the app, registering with their email address or phone number, and creating a username.
