Discounted Time Out Travel Apps

Time Out has launched a range of iPhone travel apps for London, Paris, Berlin, Barcelona and Buenos Aires. The great thing about these apps is they work completely offline, so you won't receive any roaming charges.
They have received a great review from the Guardian and four are in Apple's Top 25 Travel Apps.
They’re on sale for £1.79 for a limited time, you can get them from Time Out’s website:
