MySouthWest manager Geoff Finlay said the directory was one of the most comprehensive directories in the state with more than 9,000 listings.

When you visit the website on your mobile phone there is a mobile setting that will make looking for your particular listing easier.

Mr Finlay said the application had search categories such as accommodation or business or you can type in a key word into the search engine.

The new app is also beneficial for advertisers as Mr Finlay said they could target key words to make sure their business comes up in the results.

Since the launch of the new app MySouthWest has seen a 200 per cent increase in traffic.
