After trying 2 transfer programs on PC, iTunes, cloud, drop box, and 2 other apps this one finally worked. The best thing about this app is how easy it is to use. Create account, log in, upload contacts, log in on other device, download contact list. It literally took me longer to write this than it did to transfer my contacts. 3 hours of frustration alleviated by 2 minutes of ease with this app. Thank you
