The iPhone podcast app Castro has a lot more competition in the market nowadays since I first reviewed it back in 2013. Arguably, Castro is still the most visually appealing of the current crowd and the developers are currently working on the next major version of the app, Castro 2. In the meantime, the developers have released Castro 1.5 with some new features and a new pricing model. Following Overcast’s lead, Castro is now completely free for all to download. The company is moving to a patronage model.
