Staff at Jobcentres will help customers use the free computers
Jobseekers will be able to find out about vacancies on their mobile phones thanks to a new free downloadable app.
Employment Minister Jim Knight said the app would make it easier for people to look for jobs in their area.
It will be available in England, Wales and Scotland on the iPhone, iPod touch and Google phones.
Mr Knight also announced a pilot scheme to install 200 computers in 50 Jobcentres to help those looking for work search online and compile a CV.
He said Jobcentre Plus staff would help those customers unfamiliar with computers to use them.
About 350,000 vacancies - 13% of the total advertised by Jobcentres - now only accept electronic applications.
Speaking at the National Digital Inclusion Conference, Mr Knight said: "In this digital age, being online is not a luxury, it is a basic right."
He added that work was currently being carried out to make the app available on other phones.
