Seeking a Good Podcast App That Will Synchronize Between iPhone and Mac

I am in the process of looking for a new podcast app for my library, and I was wondering if anyone had any suggestions. I was using iTunes on my mac and Apple's iOS podcast app, but I am looking for alternatives.

The most important features to me are that subscriptions, and play back positions sink between my iPhone and mac, and that the apps can handle my massive library.

I am trying to make Downcast work, and there are things I like about the iOS and mac apps, however they both seem to be very laggy and slow to refresh. I believe this is due to the fact that I am subscribed to over two hundred and thirty podcasts, even though Apples default offerings can handle my library.

I would appreciate any suggestions or experiences.

#1 I use downcast and overcast.

I use downcast and overcast. I love overcast, but I don't like the way you cannot do batch features like deleting of podcasts and downloads you accidently started.

#2 iCatcher

My app of choice is iCatcher. It does everything I want. I do not know if it sync's with a Mac as I only use my phone for podcasts.
