British teenager Nick D'Aloisio has told Newsbeat that working on a new app with Yahoo feels like a "hobby".
The 18 year old sold his company to the internet giant Yahoo for a reported £20m in 2013 but says the money hasn't changed him.
He has just launched a new app with Yahoo aimed at changing the way we read news online.
Newsbeat's technology reporter Jonathan Blake spoke to Nick at Mobile World Congress in Barcelona.
