Liketu

According to the liketu website, this dApp is:

A new state of the art social media platform that is going to change the way you and your family and friends use social media!

While they may not be first to market with a Steem powered Instagram-like interface for Steemit, if the user experience is as lovely as the screenshots of the UI, this will surely be an absolute game changer!

Be sure to follow this project on Steemit at @liketu to be notified when the mobile apps hit their respective store.
