The app is no longer developed - don't buy it.
Used to be a great app, but it is no longer being actively updated and has fallen behind the times.
Unfortunately, this app is no longer being developed and improved to keep up with iTunes podcast requirements. For example, iTunes now requires higher quality images that are 1400x1400px. This app, however, downgrades the podcast images to 600x600 and 144x144. I just had my 243 episode podcast (nearly 5 years worth of podcasts) rejected and removed by iTunes for this reason and possibly others. It's really too bad the developer of this software isn't keeping it updated to iTunes required settings.
I've sent him numerous support emails over the past 2-3 years and they have all gone unanswered. I wish someone would purchase the app and give it a good update because there isn't any other Mac software out there that does what this app used to do quite well.
I cannot recommend this app any longer. Don't waste your money buying it. Try the trial and then try to submit to iTunes and you'll see that you won't be accepted.
