Washington: Facebook launched a mobile messaging application for Apple`s iPhone and Android devices.
Facebook engineer Lucy Zhang said Facebook Messenger can be used to exchange messages with Facebook friends but also with other people in a user`s telephone contact list.
Zhang, in a blog post, highlighted Messenger`s group messaging capability.
"When you`re on the go, coordinating a bunch of people can be tricky, especially if plans change at the last minute," she said. "With Messenger, you can quickly start a group conversation and message everyone at once."
Facebook said Messenger also has location- and photo-sharing features.
"If you choose to add your location, the people you`re messaging with can easily find each other on the map," Zhang said. "You can also attach photos, so everyone else can see and comment on what you`re looking at."
Messenger integrates text messages, instant messages and emails.
Zhang is a co-founder of Beluga, a startup founded by former Google employees that allows users to send group messages to family or friends.
Facebook acquired Beluga in March.
