The latest company trying to give online influencers a space on their fans' smartphone homescreens is Israeli startup Swiftic, which is launching its branded apps platform this week.

The company says it is targeting influencers with more than 50,000 followers on Instagram, Facebook, YouTube and Twitter.

The apps will keep fans updated with the stars' latest social posts, but will also help the latter launch their own mobile stores, and charge subscription fees for exclusive content.

YouTube musician Lenay Chantelle Olsen is one of the first to sign up, working with Swiftic to create an app that will be aimed at her 4.5 million subscribers on Google's video service.

For now, Swiftic's platform is invitation-only in closed beta: it's encouraging influencers to register their interest on its website.
