GPSmyCity app

iPhone users can load over 2,000 walking tours of more than 180 cities worldwide with GPSmyCity applications.

Each walking tour features still pictures of sights with text, turn-by-turn navigation and walking directions and a “FindMe” autotracker (so you know you’re headed in the right direction). The tech is not Internet based, so there are no roaming charges.

You can download a free demo sample before buying a city’s app ($2.99-$4.99, depending on the number of tours in that city’s package). Tour authors are required to have resided in their cities for at least six months. Visit www.gpsmycity.com.
