Worked Perfectly
I have iPhone 4 and iPad 3rd gen. Tried syncing between iCloud and didnt like it...too squirrely...so went back to syncing both with my laptop. When I got rid of iCloud I made the mistake of saying keep the contacts on the phone and ended up with double entries. For some reason, syncing to laptop didnt result in doubles there and using iTunes to overwrite the contacts file didnt work either. This app cleaned up 700+ duplicates--easy as pie. I did notice that it appears to stop or pause when the phone went dark but a quick touch on the screen followed by a couple more to keep it awake was all it needed. Great app!
