Twitter's Periscope officially goes dark on April 1

As scheduled, Twitter will officially shutter its Periscope livestreaming service on April 1, though most of the app's core functions have already transferred to Twitter Live.

Twitter announced the pending shutdown in a tweet posted to the official Periscope account on Wednesday.

"This is it. Our final goodbye. Today is the last day the Periscope app will be available. We leave you with our gratitude for all the creators and viewers who brighten the Periscope community. We hope to see you all live on Twitter," the tweet reads.

Twitter in December announced plans to shutter Periscope this month citing waning usage and increasing maintenance costs. At the time, the company said Periscope was quickly becoming unsustainable as its user base had declined over the past couple years.

Periscope was purchased by Twitter in 2015 and the app went on to win an App of the Year award from Apple.

Once Periscope shuts down, the service's website will transform into an archive of past broadcasts. Users can also download a full archive of their own data and video clips, Twitter said.

Though Periscope will be no more come Thursday, the service's core capabilities will live on in Twitter Live.
