Have not used the desktop sync program. I just copy the wallet to desktop as a backup. Never had any problems. Very happy to have an app that continues to be supported after initial purchase without having "add-on" purchases for previously purchased function. It is independent from other online services which I like. Note that I have had this app since the iPhone 4 and currently am using it with the 5s have not updated to iOS 10
