I don’t have to worry about losing great podcasts if the channel or podcasts are no longer available.

by Ru*****, 2026-08-21

Hello, I really like this podcast app. It is the best podcast app that I have found and I really like the UI. I just bought the app. Whenever I go to download an episode, the progress bar reaches 100%, but then the episode says that it is not downloaded and it shows that I can download it again. I click the download button and it does the same thing. Also, when clicking the transcribe or generate chapter buttons, they stay greyed-out, and nothing resolves. I’m unsure if this depends on the podcast episode being downloaded or not, but the transcription and generate chapter buttons do not seem to work. I don’t know if they have progress bars to monitor them, but if they do not, could you add that feature? EDIT: I did figure out that I needed to enable “AI Processing on Battery”. However, I am still unable to generate chapters on battery. Even if it is not recommended for one to do this, could you add the ability for one to do so? Also, I’m unsure if the SOTA models are less intensive. Also, I have bought the podcast app Aisten as well. It does a wonderful job in transcribing podcast. It uses the SOTA V1, V2, and V3 engines to transcribe the podcasts. I was wondering if you could also add these as options to select to do the transcriptions? It also has a feature to both bookmark (saved only when viewing that specific podcast) and favoriting (a global way to view all favorites across all podcast) different lines of texts within the transcription. Could you add a feature similar to this? It would also be nice to have bookmarks for specific time codes. It would be nice to have a way to add notes to time codes, as well as having a note section for the given episode. I would like to use this app to do a little research. Another feature that would be cool is to be able to export a selected segment of the podcast’s audio. Thank you for your efforts. This podcast app is amazing. If there are other features I think of, I will update my review. Thanks
