6. London Olympics 2012 - 50p

Android

This app gives you a whole bundle of useful info if you're heading to the Games – even at venues outside London. As well as weather forecasts, live traffic information and a venue-by-venue or day-by-day fixture list, it's got an Explore section, containing places to visit, stay, eat, drink and party in between watching the sporting events. The only downer is that the Underground map it contains is several years out of date, and so is missing some of the new rail links around the Olympic Park.

8. London Tube Deluxe - 69p

iPhone, iPad

If you're going to the Olympics in London, chances are you'll be using public transport. To help you plan your journey and keep on top of any disruptions around the capital, get yourself a copy of London Tube Deluxe, which has Underground, Overground and National Rail maps of the capital (all of which work without an internet connection), as well as a route planner and live line updates. While you'll need an internet connection for the latter services, remember that increasing numbers of Underground stations now offer Wi-Fi deep below the surface.

9. London Bus Buddy - Free

iPhone

If you'd rather see a bit more of London on your way to or from your Olympic events, why not take the bus rather than squeezing onto a packed Tube train and travelling in dark tunnels? London Bus Buddy uses Transport for London's data to give you live departures from any bus stop in the capital, route information and a journey planner – which will work offline as well as online.
