Regional business news network TheBusinessDesk.com has launched a free-to-download iPhone app.

The smartphone application will complement the network’s three websites, which cover the north west, Yorkshire and West Midlands. To use the app, readers will have to be registered on one of the three sites.

“Having built up more than 35,000 registered users across our sites, it is important that we continue to innovate and make it as easy as possible for our users to access up to the minute regional news whether in the office or out and about,” says Chris Barry, north west editor of TheBusinessDesk.com, in a story on the site (registration required).

Launches for Blackberry handsets and other mobile apps are planned.
