Thank You...

As an indie developer, I want to first express my everlasting love and thanks to my two biggest supporters - my amazing wife and daughter. Both of them provided me some great feedback, patience during late night coding sprints, and overall have been my biggest cheerleaders to pursue this dream of building CastKeeper. My amazing wife even started getting more into podcasts just to show her support, and thank you honey! For my daughter, you may find her influence in our achievements section (she'll never tell the secret!).

Further, our excellent beta testers deserve a huge thank you for making this happen. They're support, feedback, ideas, and suggestions are everywhere in the app you will use today, and will see in the future. So as you enjoy CastKeeper, remember it took a lot of dedicated supporters to get us here, and continue to help with our journey.

CastKeeper is just getting started...

This initial launch is just the beginning of CastKeeper. In the future, CastKeeper will cotinue to grow its functionality and add more quality of listener features.

As usual, you'll find any future updates on this page, so be sure to subscribe to this page via RSS to get the latest updates.

CastKeeper Release Candidate Now Available!

CastKeeper is now in the release candidate phase. After months of development, weeks of testing, and a lot of help from family and friends of CastKeeper, the app is now ready to enter the final stages for App Store approval.

This past week the focus has been mainly on three things: Speed, Stability, and Engagement. Before release to the App Store soon, ensuring a fast, stable, and engaging experience is the top priority. In this Release Candidate, you'll find some things no longer in the same place you used to find them, a more stable experience, and an all-new way to track your podcast listening on CastKeeper.

Let's dive right into the changes, improvements, and fixes in this release:

• New Streamlined Full Player: The full player in CastKeeper has been streamlined to get you the information you need, or the actions you want to perform, with less buttons. In the Full Player, you can now swipe where the podcast image used to navigate between the episode's artwork, chapters, AI summary, hosts, and transcript. Alternatively, you can tap on the card image below as well to quickly jump between each.
• New Achievements: Check out our brand new Achievements in the Settings screen near your listening stats. Earn achievements by listening to podcasts, and see if you can earn all of our platinum level achievements. Also, you'll find some rare achievements that will unlock when completing specific secret missions. See if you can figure them out!
• Improved Episode Detail View. Increased performance with our Episode Detail screen, and moved the share button to the top right menu. Our previous layout was a little tight for those with smaller devices.
• Improved Overall Speed and UX Responsiveness. CastKeeper will feel more fluid from launch and throughout the interface.
• Improved OPML Imports. CastKeeper's OPML import has been improved significantly for speed and accuracy.
• Improved AI Chapter Generation for more accurate chapters.
• Fixed issue with requesting new Hosts or updating Host information.

What's Next?

The deadline to submit any more feedback will be April 13, 2026. This weekend, we will begin our App Store launch preparations, and address any critical feedback before our final submission to the App Store. If you haven't tried out all of CastKeeper's features yet, or were holding off telling a friend about the app, now's the time to do it.

Once CastKeeper has been submitted for App Store approval, this page will be updated with our launch details.

CastKeeper Public Beta 5 Release

Happy Monday! As CastKeeper continues to get closer to a public release, the focus has shifted now to quality of listener improvements and bugs. Since the last release, a lot of great feedback has been received, and keep them coming!

While the next CastKeeper beta release was scheduled for next week, a new release is being put out earlier to ensure the most quality experience for our testers, and upcoming users.

Improvements in Public Beta 5:

• Enhanced Search. Search results will now include two paths, Podcasts and Episodes. Entering a search term will return the podcasts where that term is found, as well as a new section called "Episodes" where users can find the specific episodes where the search term is found. Looking for just that one episode where something was mentioned, or an interview took place, use the Episodes filter. Episodes found can be quickly added to the "Listen Later" collection.
• Archive View Enhancements. The Archive page has been reworked to make filtering, ordering, and searching archived podcast episodes easier. Users can now filter by storage location, as well as change their sorting mechanism. A dedicated search bar has been added to locate a specific archived episode.
• Silence Trimming Improved. Continued to improve our silence trimming algorithm for better results.
• New Controls for Full Screen Video. You can now favorite, bookmark, or change output audio target for video podcasts when in full screen mode.
• UX Polishes. In the spirit of dyeing Easter eggs, CastKeeper has added some more polish with consistent color schemes and navigation throughout the interface, along with some UX changes to make finding important information easier.
• Speaking of Easter Eggs, there may be a little one hidden in the UX somewhere. Happy hunting!

Bugs fixed in this release:

• Fixed issue where Full Player did not show friendly names of archive locations when using archive button.
• Fixed issue where hitting skip chapter forward on the last chapter would restart last chapter instead of going to the end of the episode.
• Fixed issue where AI-generated chapters without a saved transcript would not show in the Full Player chapters picker.
• Fixed issue with RSS where episodes were not pulling in for podcasts.

That's all for today's release.

CastKeeper Public Beta 4 Release

This past week I've finally nailed the one last feature I was saving to make sure it was done right. With Public Beta 4, CastKeeper now supports Video Podcasts. While the podcast "purist" in me still prefers the audio experience, video podcasts are on the rise. To ensure our video podcasters get the same love as our audio-only feeds, I wanted to personally make sure this worked.

Here's the full breakdown of how video podcasts are now integrated into CastKeeper:

• The iTunes API doesn't allow multiple file types in a single podcast feed. So if you see a podcast titled "Video", that's your best bet.
• Despite being a video podcast, I've retained the ability to go "audio only" for those times watching isn't easy. Simply tap the "camera off" icon in the Full Player to go "audio only". And when you're ready to resume watching, touch the same icon to resume video seamlessly.
• Video podcasts will natively support picture-in-picture, full-screen mode, and when closing the full player you will see a tiny live video in the Mini Player. Tapping the mini player will resume the Full Player with the video.
• Video podcasts support a seamless transition to "audio only" when the phone is locked or display goes to sleep to continue playing the audio in the background. This is very similar to how YouTube TV works and it's a wonderful feature.
• Resuming an In Progress (paused) episode in our now renamed, "Continue Playing" section on the Home tab will automatically open the full player and resume the podcast in the last mode you left it. So if you paused it in video mode, it will bring up the full player and video. If you paused it in audio mode, it will continue in audio mode. Simply head over to the player to resume the video.
• Bookmarking video podcasts for "Save For Later" will now be separated into an automatic "Watch Later" collection. "Listen Later" remains for audio-only podcasts.

This release also includes some key changes and improvements since the previous release, including:

• Sleep Timer UX Improved. The previous build's changes to the sleep timer we're not a responsive as oriignally envisioned. In this release, the UX for sleep timer has been improved from to a one-step screen. The radial dial has returned is much more responsive on drag, as well as quick buttons to add or remove time.
• AI Chapter Improvements. Generation of AI Chapters no longer requires you to permanently store the transcript. The system will generate a temporary transcript to create the AI Chapters, but immediately remove it from memory. Users can generate a transcript for permanent transcription separately. The UX has been reworked to pull the Generate Transcript button to the top of the Episode View.
• AI Chapter Algorithm Improved. This release includes updates to the algorithms to AI Chatper generation for more accurate chapter markers and name, and improved ad detection from transcripts when generating AI Chapters.
• Browse and Manage Archives Within the App. This feature was previously available, however, was in the Storage Usage in the Settings. You can now find this right below Storage Usage on the Settings page. In this view, you can see all of your archived episodes, including transcripts and chapters, and delete them from within the app. A new filter has also been added to filter not only by file type, but also by Storage Location for larger libraries.
• Performance and UX Updates. This release includes performance updates and optimizations, and small UX adjustments.

Bugs fixed in this release:

• OPML imports will now show podcast artwork after imports, and improved matching. A big thank you to beta tester T.E. for reporting this issue.
• Fixed rare crashes occurring with Silence Trimming, speficially when streaming an episode.
• Fixed some minor bugs and issues.

Thanks to everyone who has supported CastKeeper on this incredible journey, and I'm looking forward to bringing it to the world soon. Next week's release will be the last release, and is planned as our Release Candidate version. At this time, no more new features are planned, only bug fixes or quality of listener improvements. If you have any feature requests, I still want to hear them, as after launch the plan is to continue to improve CastKeeper.

Launch plans and information will be included in next week's release notes. In the meantime, please feel free to refer other podcast users to the beta through the website. We still have a few open spots left, but spots are filling up fast!

CastKeeper Public Beta 3 Release 2 Out Now

Thanks to everyone who has given me such awesome feedback, that I've released my next build earlier than expected.

Release 2 of Public Beta 3 is available now, and I will be expiring old builds from testing due to many changes and ensuring testers are on the latest version.

The full changelog is below:

What's New in this Release:

• NEW COLLECTION TEMPLATES: We've revamped collections to add some fun quick-to-add collections that you can use. We've also refined the manual collection creation to allow users to futher refine Smart Collections or Manual Collections. Check it out!
• I've made some significant improvements to our Trim Silences feature to reduce jitter and clipping.
• NEW SLEEP TIMER UX: Revamped the sleep timer process to make it easy to start a timer, and now you will see a live view of the night sky overhead when setting a sleep timer. If one isn't available, a beautiful night view from Apple Maps will appear.
• Added a close buton to the Mini Player that is available when audio is not playing or loading. Thanks to tester Ruben for this suggestion.
• Cleaned up some very minor UX issues and performance tuned for older devices.

Continue with the great feedback! CastKeeper is a better app because of our testing community. I'll be taking a few days to work on other things and await more feedback, but this one I felt needed to get out ASAP. Our next release will include a really good addition that I think you all will definitely like. Just ironing out some of the final code. Stay tuned!

CastKeeper Public Beta 3 Release Notes

I've spent the weekend getting great feedback from our testing community, as well as making some more final preparations before our launch. I want to give a big thank you personally to everyone who has contributed their feedback, and I appreciate everyone so far enjoying CastKeeper.

So let's get down to the good stuff. Public Beta 3 is out now, and in this release, I've added some "Quality of Listener" improvements, along with some minor fixes.

The full changelog is below:

New Features for Beta Testers:

• Multiple S3 Buckets From Same Provider Type Support. Previously, only one bucket for S3 account providers was allowed. Now users can add as many S3 buckets they would like from the same provider, including Custom S3 servers. So whether you happen to have multiple Wasabi buckets and want to separate your archive, or run a homelab with a bunch of S3 buckets, you can now add these to CastKeeper. This does not work for iCloud Drive.
• Normlize Audio for Playback. Go to Settings and enable this feature to boost lower sounds and reduce louder sounds, like ads, to maintain a consistent audio volume at the level you set. A big thank you to my amazing wife for this suggestion!
• Trim Silences has arrived. Enable this in settings to have CastKeeper automatically trim out long pauses and silences during episode playback to save you more time for more podcasts. Thank you to tester "startfragment".
• Listening Stats with Charts. Check out our new listening stats in Settings where you can see just how much time you've saved using our Trim Sliences feature, as well as some other information. All information is stored privately and synced through iCloud and cross-device. Each section includes a little chart for a quick glance.

Improvements in this Release:

• Cleaned up the Settings Page and added information buttons you can tap to see what each toggle does in a popover.

Bugs Squashed in this Release:

• I received some feedback from an English teacher who kindly reminded me that new sentences should not start with a number. So I wrote a small essay of code to fix that in our greetings as my way of saying thank you, and I'm sorry.

We've really started making some great progress towards launch, and I appreciate everyone's feedback. Remember, if you have any feedback, and prefer to send it to me directly, please email me at [email protected]. I will do my best to personally respond to each of you as soon as possible.

CastKeeper Public Beta 2 Release Out Now

CastKeeper Public Beta 2 is out now for continued testing. In this release, I've squashed some bugs, and introduced more new features and improvements to make the CastKeeper experience better in preparation for our launch.

The full changelog is below:

New Features for Beta Testers:

• With the release of iOS 26.4, transcriptions now automatically use Apple Intelligence's latest frameworks for faster transcripts, with less battery usage. Users with devices that support Apple Intelligence will automatically get access to this feature. For older devices, WhisperKit is still available, but it is suggested to run transcripts on battery due to heavier work to preserve battery life.
• Translations now leverage new frameworks to transcribe your transcripts using Apple Intelligence. Watch as your transcripts go from one language to another as they are processed. Older devices will need to continue to download the appropriate language packs and use the older Translation APIs.
• S3 Provider setup has been simplified to allow a faster setup, including pricing links to our preconfigured providers, helping you choose the plan right for you.
• You can now create a new S3 bucket or select an existing bucket on your service after configuration.
• Users who set up a custom S3 server can now set a "friendly" name for the server like "My Homelab S3" and the UI will show that throughout so you know what specific S3 bucket your episodes are in.

Bugs Squashed in this Release:

• Episodes played from Archive with a sleep timer will correctly mark episodes as played when they finish.
• Improved Smart Collections for better results.
• Improved AI Chapter generation engine to better detect advertisements and increase accuracy.
• Transcript View should no longer duplicate "Chapters" and "AI Chapters" with AI-generated chapters.
• Due to Apple's strict guardrails with Apple Intelligence, tweaked the AI Episode Summary generation with fallback handling if running into safeguards. Apple's strict control of Apple Intelligence caused some extra work, but it's private, just how I like it.

Coming Soon:

I'm currently working on revamping the Hosts feature for a better experience for users, as well as our beloved podcasters. Most of this work will occur outside of the app, but stay tuned here for an update when it's ready.
