Mapping App

I have come to know this forum as an expert for my iPad addiction, so I hope for a suggestion of one of the brilliant contributors.

On my PC, I use a program called Microsoft Streets and trips. Its a program useful to import a list of addresses on a worksheet and remove the as pins on a map to see a more visual representation of the place where in space that they are.

I have a list of new customers of perspective that I want to do it with for convenience however hoped to do on my iPad. Someone has a suggestion for an application which will complete this need?

Thanks in advance.
