An early morning delivery sends the candidates into the fast-paced world of technology. Lord Sugar challenges the teams to think big and go global as they must design, launch and promote a new mobile phone application. In the battle for downloads, the teams must create a mobile app and pitch it to three influential technology websites to become 'App of the Day', as well as attempt to convince a huge crowd of bloggers and software experts at a major gaming fair to support the application and increase downloads. With their apps downloadable for 24 hours, a dramatic result leads to a fierce boardroom battle, and one more candidate faces Lord Sugar's immortal words: 'You're fired'.
