    Deleted all Duplicate contacts with ease. Brought the pro version to support Dev as many more features available that were of use..

    Downloaded another contacts all and it couldn't find duplicates. This one found hundreds that I had because of google sync not working right. Thanks.

    Don't install this. It's total crap that will bug up your systems. Shovels mountains of dirt and worms it's way through your devices until everything is wonked up. Better off just bricking your phone.
