A smartphone app which provides summaries of news stories soared to number nine in Apple's app store just two hours after its release in the US.
The app, called Summly, was designed by 17-year-old Londoner Nick D'Aloisio, and has received more than $1m in funding from investors.
High-profile supporters include Stephen Fry, Tech City CEO Joanna Shields and Newscorp owner Rupert Murdoch.
However some early reviewers have described the app as "confusing".
"Navigation unclear," wrote Oliver Devereux on the app store's review page, while another described it as "quite unintuitive".
But the app is still rating an average score of four out of five possible stars from users overall.
Mr D'Aloisio took time off school to develop his idea for a smartphone application that offers summaries of existing news stories published on the net.
The free-to-download app uses algorithms to process news stories into summaries which users can then swipe to see in full if they wish.
"We worked hard on an interface that looks like nothing else on iPhone," he told the BBC.
"We merged algorithm with beautiful design. It's summarising thousands of articles every minute."
