If you’re one of the lucky ones to be attending the Olympics this year in London, but are a little nervous about navigating a foreign city—particularly during what will very likely become a rather chaotic time with the huge influx of travelers and athletes—there are a few apps out there that can help you out. (And most of them will still be useful outside of London, after the Games are long over.)

London Tube Deluxe Navigating public transportation can be confusing, but this app clears everything up. Not only does it tell you how to get from A to B, it provides updates on service interruptions, high-res maps, and train departure times. iOS; $.99.

London Olympics 2012 Ultimate There’s a lot going on at the Olympics. There’s no way you’ll be able to see everything you want. But that doesn’t mean you can’t keep yourself updated. This app lets you read updates (and be automatically updated as your favorite countries win/lose), keep up with the medal count for each country, see a full schedule of all events, and more. Android; free.

Tagwhat Don’t take for granted that you’re in a strange city in a foreign country. Take in all you can! This app is great for learning about everything that’s surrounding you. Just open the app, and discover that the street you’re walking on was actually one that your favorite musician filmed a video on, or that the café you were just going to breeze by without a second thought is actually the city’s best-kept secret. Android; iOS; free.

XE Currency App Be prepared ahead of time, and then keep yourself up-to-date, with the exchange rate, so there are no surprises when you get home and see your credit card statement. The app also lets you calculate the most recently updated rates, even if you have no signal or internet connection. Android; iOS; free.
