Unlike — the top notch city guide website — has just released a killer iPhone app full of food, art, fashion, events and urban culture, as well as some other very useful features. Using the iPhone’s GPS, Unlike can pull up a map of attractions, making you an instant expert. Plan a tour, save all your info, and then go walk the city. Most of the locations are international, which usually means roaming charges or finding a wifi spot. But the Unlike app downloads all the necessary info, so no need for an Internet connection. Individual city guides include: Amsterdam, Barcelona, Berlin, Copenhagen and London (more cities coming soon). They’re $4.99 each, or you can the buy the whole enchilada in one app for $19.99.
