I really like the layout of this app BUT the developer should make it clear that the option to transfer data to Money Pro, this is one way only, from Checkbook to MP. This creates problems if you enter transactions in MP too, they do no sync, they duplicate. The first thing the Checkbook does on opening for the first time is offer that option, without an warning that this is not a sync, as most people would think.
