Castro was updated to version 1.5 today with some great new features like Spotlight search, in-app Safari, and support for 3D Touch. Another change that went live today? It’s now a free app, every feature is available without charge, and they added an optional non-renewing patronage model. Sound familiar? In my original Arment piece, ‘The Elephant in the Room’, I said: “What he is most certainly doing is increasing the odds that no other third party podcast app will feel viable in the market by charging up front for their offering.”
