Skobbler has unveiled GPS Navigation 2, a new sat nav app for Apple iPhone owners.

The app, which is priced at £1.49, offers both online and offline navigation for the whole world. When in range of a data connection, iPhone users can receive visual and audio navigation to a specific location. Alternatively, for a small fee, which starts from £2.49, GPS Navigation 2 users can install a specific map to their smartphone ensuring that loss of data connection doesn't result in a loss of navigation.

Just like Skobbler's previous app, Skobbler Lite and Skobbler Premium, GPS Navigation 2 uses OpenStreetMap (OSM), a Wikipedia of free maps, that currently has some 250,000 users creating and updating existing maps. Users are also encouraged to make corrections and update the maps, to make "outdated and poorly detailed maps a thing of the past".

Skobbler also says the app features a redesigned interface, the ability to remove maps as necessary, ideal for smartphone users that are reaching the storage limit on their handset, and has been streamlined for faster performance.

Users will also benefit from free driving" mode that ensures a map can be viewed without entering a destination, along with an "extensive range" of Point of Interests (POIs) marked on maps, co-ordinate based navigation and the ability to send your location to friends via email or Facebook.

"We're confident that GPS Navigation 2 is the future of sat nav," says Marcus Thielking, co-founder of skobbler.

"Giving users the option of utilising either online or offline maps, and choosing which to install or remove depending on their needs, is a big step forwards. It's like having a virtual map in your pocket, and with free driving and a browsable map mode our customers will never feel lost again."

Skobbler also revealed the £1.49 app is available for free until Sunday October 16.
