Instagram is gearing up to take on Vine by offering a new video sharing service, according to a source familiar with the plans. The move is expected to be announced on Thursday, June 20, during a mysterious Facebook press event at its headquarters in Menlo Park, California.

Vine, the six-second video sharing service from Twitter, is finally available on Android, more than four months after it made its debut on iOS. The app is ready to download now from Google Play, and it gives users the ability to share their clips with the 13 million people already using the service.

The app also has a new feature that’s unique to Android.
