To help you make the most of your time in London while you're at the Olympics, we have launched a new version of our interactive guide to the city compiled by Guardian writers, bloggers and local experts. As well as all the good stuff we've been adding in the build-up to the Games – such as Tony Naylor's guide to the best budget eats around the main Olympic venues – we'll also be adding 100 new tips featured in this Saturday's Guardian, and have mapped an extra 50 things to do for free in the city.
But the biggest bonus is that you will now be able use the guide while you're out and about on your smartphone device or tablet. This responsive version of the guide has a location-aware function and serves up tips based on the user's current position. It also allows you to filter your search by themes – where to stay, shopping, nightlife, arts etc. How to get it: go to guardian.co.uk/travel.
