I named it Digilore, available here: https://apps.apple.com/us/app/digilore/id6633130387

This app searches the Podcast Index https://podcastindex.org/ that's uncensored. Apple podcast search, what most apps use, removes 3 or 4 podcasts a day, according to the Podcast Index. Digilore also supports their new RSS tags such as for transcripts and live episodes. The namespace spec is here: https://github.com/Podcastindex-org/podcast-namespace

Digilore works on MacOS and iOS and will soon support Android. I've been a backend Java services developer for 15 years and recently ventured out into mobile apps. It is written using the Flutter SDK (Dart language) which is cross platform (iOS/Android/Mac/Win/Web). It's been a joy to use Flutter, and I highly recommend it. Granted, it's a Google product, so some people might be skeptical of it.

I am not monetizing this with freemium features or as a paid app. It follows the "value for value" model of funding where users are asked to consider the amount of value it brings to them and contribute that amount, via in-app-purchases. It's a twist on shareware and many podcasts follow this model which was my inspiration that you can read more here: https://value4value.info/about/
