Synching podcast app

Looking for a podcast app: I want:

1. to 'control' podcasts from my iMac (10.9.5)… subscribe, add, delete and download etc


2. to synch from either Mac or iPhone (6 Plus, iOS 8.1) and have the podcasts which I've downloaded at home available on my iPhone


3. not to have to stream podcasts via cellular data

iTunes/Podcasts.app is buggy; InstaCast doesn't allow transfer from iMac to iPhone; DownCast doesn't synch properly - at least not until Yosemite.



Any suggestions, please?



TIA!
