Travel Apps for London and Paris

Apple iPhone - Recommendations for Travel Apps for London and Paris

Any recommendations for apps that would be useful for a family vacation to London and Paris. Particularly apps that don't require wireless access to work as we don't want to pay the high roaming data rates.

Kids are 9 and 6.

But even more, use iTunes to download Rick Steve's podcasts, Rick Steves' Paris Audio Tours (particularly The Louvre, the Orsay, and Versailles, plus the neighborhood guides). You'll be able to bypass the rented audio guides and enjoy a professional tour of the museums' highlights.

In London, the podcast London's Best Free Walks offers you tours around a host of neighborhoods. Rick Steves also offers London Audio Tours, but they were released after my last London vacation, so I cannot vouch for them directly.

Thanks. Had already downloaded the Rick Steve's podcasts as we had gotten his paper guide book for London.
