Update 2 (July 12, 2014; v. 1.2.2): Updated version of the app, still very spotty functionality. Sometimes it can transfer files (half the time), other times it cannot. Sometimes it crashes for no reason, other times not. Sometimes it allows you to actually delete one file (with the message “this will remove 1 file”), but most of the time it will give that message and then proceed to delete all files. Has the developer ever tried using this app himself? It’s pretty obvious where its multiple shortcomings undermine its promise. I keep coming back every few months to see if he’s fixed it so as to make it a reliable solution. The answer is: not yet. Avoid for now.
Update 1: Still crapware with version 1.1.0 at least on Mountain Lion and iOS 7 (both fully patched). The iOS device never connects to the iMac to, you know, actually transfer the file. Developer also finds it too burdensome to respond to inquiries about this core functionality failure.
I used the beta versions of this app for months, and while not perfect they were generally fine. This v. 1.0.1 of is a step backward into non-functionality. Im unable to transfer files at all, despite having changed nothing on my computer or network since the beta versions worked. Wait for another version with a major fix or find an alternative.
