Discount designer etailer the Outnet.com will launch its first edition iPhone app this week, which rewards users with credit for introducing friends to the site.

The app, known as StyleCred, will launch on Thursday and allows users to share looks with friends and earn a £20 credit every time a friend new to the Outnet shops there for the first time.

The launch comes seven months after the Outnet, which is owned by Net-a-Porter.com, launched its mobile-enabled website allowing customers to shop online from any device.

The app, which is free to download, is automatically in sync with the Outnet website and is updated with the latest product arrivals every Monday, Tuesday and Thursday.
