Back in the day I had an app that downloaded my podcasts to my iPhone 3S every morning over wifi before I listened to them on my way into work. Then Apple added podcatcher support to iTunes, which at the time was a program you ran on your Mac or Window PC to use to get music onto iPods or iPhones. Sadly, I'd just started using Ubuntu so that wasn't an option for me, besides the inconvenience of having to do that manually every morning. I put together a hacky solution in the short term, then moved to Android.
