Twitter on Thursday officially launched Periscope, a competitor to Meerkat that allows users to livestream daily happenings – whether it’s a meal, a concert or a puppy playing – right to followers on the social network.

Followers can then comment and like the stream in real-time for the broadcaster. “Going live will instantly notify your followers who can join, comment and send you hearts in real time,” Periscope said. “The more hearts you get, the higher they flutter on the screen.”

The Periscope app had previously been in a closed beta stage following Twitter’s acquisition of the company earlier this month. After that move, Twitter cut off Meerkat’s access to its social graph, in a likely effort to promote users to use its own platform instead. Re/code explained that Periscope is different than Meerkat in that all engagement is reflected inside of Periscope instead of on Twitter.

You can find the app in the iTunes App Store for iOS now. It’s not currently available for Android.
