Chat Apps are increasingly being used to replace SMS text messaging where it is free, offers group messaging and photo/video sharing.
Snapchat is a video messaging application. Users can take photos, record videos, add text and drawings, and send them to a controlled list of recipients. These photos and videos are known as ‘Snaps’. They delete automatically after a set amount of time unless the other user chooses to screenshot the snap. When a snap is posted the chosen recipient gets a notification.
Yik Yak is an app that allows people anonymously to create and view “Yaks” within a 5-mile radius. All users have the ability to contribute to the stream by writing, responding, and “voting up” or “voting down” (liking or disliking) yaks.
Other examples include:
- Kakao Talk
- Facebook Messenger
- Google Hangouts
If you want total privacy, Telegram is an app where messages between users are free and private, and you can initiate a secret chat, which heavily encrypts messages user-to-user with a unique key, to avoid interception.
