The podcast app I use is Podcast & Radio Addict and I find it adds so much value to my life that I purchased the advert-free version. 

Having podcasts ready for those hours that would otherwise be quite empty, like long road trips keeps life interesting. You really can learn something new everyday. Remember: learning keeps you young! Having an open mind and listening ears is all that is required for becoming a podcast addict like me...

Bring rich and exotic conversations and ways of thinking into your days. You never know where an interesting new idea may lead you...

Let me know of any podcast recommendations you have! I am always eager to learn new things. 

Happy listening & learning!
