I haven't used iOS or Android, so I don't know what those apps are like, but I use BringCast. It remembers where you were in a podcast episode, so if I stop in the middle of one of my lower-priority podcasts because a new ep came out in one of my higher-priority podcasts, I can listen to the higher priority one, and then go back later to the one I was listening to, and it will take it from where I left off.
