I purchased this while facing the daunting task of transferring my wifes contacts from her Samsung Magnet to her new iPhone 5. I had already figured out how to make the .csv using Samsung PC Studio, and this app did the second part very nicely. Directions were easy to follow and even though I have tinkered with mapping fields in different scenarios before, this app walked me through the steps and graphically displayed what was happening where appropriate. Very easy to use; about as easy as you can make this moderately technical task.
