I have used SimpleFTP for a long time. I forget what I used in the mid-90's, but it was crude. Still, it sufficed for a long time. Eventually, it was rendered obsolete by OSX, as I recall. That's when I found Simple FTP. Never a glitch for many years. I'd transfer bookmark and prefs folders from one computer to the other, etc., and it always did exactly what I wanted, which was to provide a simple, stable, intuitive FTP interface.So, when I decided to upgrade to version 4 not too long ago, via the App store, I expected more of the same rock solid performance. And I got it - except for one odd glitch with one of my servers. I won't go into the gory details, but it made me nuts. I emailed these folks, thinking it was another snowball thrown into a black hole.I was pleasantly surprised to get a reply within a day. They analyzed what I told them and actually fixed the problem. Then, they told me that it would be bundled into the next version. That alone made me like them. Here, finally, was a company that cared about its customers. I was double pleased to have just gotten an email a short time ago, telling me that the new version was out! Now, THAT'S service. I just updated and, sure enough, it does work perfectly.Thanks again! Great FTP software and a great company.

The app crashed every time I tried to use it. Useless. Don't waste your money. It never works.
