Tired to jump from one app to another when you use location based search app? iFound is another one, not just that. It has the gas price in US, it has the map view and directions in the same app. You can just back when you want to look for another result, you don't have to quit to another application and jump back back. Using the iPod touch or iPhone 1G, not accurate enough to get the location? Goto the current location map, adjust it yourself. And just one tap away to most recent locations, search histories make it easy to use.
