Inventor of the world wide web says apps are rubbish
Tim Berners-Lee, creator of the world wide web, has spoken out against smartphone apps.
In the Guardian newspaper, he said they were creating a "closed world" because information on them can't be searched for on the web.
It means stuff that could be shared on the internet gets trapped within individual apps, so it's not available to everyone.
Tim also criticised government plans for snooping on the sites people visit.
