Google's official app makes it easier for two users to communicate. Hangouts have replaced Google Talk with new instant messaging features.
In Hangouts, you can express emotions through different visuals, such as photos and emojis.
Hangouts show the user's friends online if they type/send a message. The user can switch from text mode to video mode. You can chat with up to 10 users at once in the program.
A feature of Hangouts is to start a conversation with any user on one device and end it on another. Also, there is no invisibility mode in Hangouts.
