Earlier this week, Yahoo launched a new iPhone app called Sketch-a-Search that allows you to trace an area with your finger to get restaurant results in a specifically defined region.

We had a chance to sit down with Director of Product Management Ariel Seidman for a demo of Sketch-a-Search, and got a window into future expansion of the app.

While limited to restaurant and cafe results right now — putting it in competition with apps like Yelp and Urbanspoon — expect more types of data to become available on Sketch-a-Search soon.

More regions in the U.S. will also be supported beyond the 32 major metro areas served currently, as well as international markets like the UK, Canada, France and beyond. Expect other platform support to come soon as well, with Android being top of that list to see a Sketch-a-Search app.

What apps do you use to get local information at your fingertips?
