Did you know that Chicago is home to the world’s largest collection of impressionist paintings outside Paris? Did you know that the city has the world's largest Tiffany dome, at the Chicago Cultural Center, or that the "Historic Route 66" begins in Chicago at the famous Grant Park? Discover all this and more with our professionally designed sightseeing tours. PocketGuide, the world’s leading audio city guide application, reveals the best stories, insider hangouts and must-see sights in more than 100 major cities and tourist destinations. PocketGuide turns your mobile device into a personal tour guide: The GPS figures out where you are, and a voice recording, made by a local guide, describes the sights around you. You don’t need to read text from your phone, just listen and enjoy a city’s attractions while your virtual tour guide explains it all and shares personal insights. PocketGuide works offline, so you save on roaming charges, and it includes an offline map and loads of critical reviews that help you decide where to eat, drink and shop. We also have fascinating themed tours, for those who want to go off the beaten path. Find the top tapas in Barcelona, get chic in NYC’s East Village or follow the trail of a 19th century serial killer in London. Whether you're interested in the main sights or "the road less traveled", PocketGuide is ready to take you there. Please note that continuous use of GPS running in the background can dramatically decrease battery life.
