Save, Sync & AI, Privately

₪17.90 · Designed for iPad. Not verified for macOS.

Your podcast app shouldn't need a side hustle. Play, follow, save, sync, and use AI—privately, no ads, no tracking, no subscriptions. One purchase, all devices. CastKeeper: Your Podcasts. Yours Forever. Some people collect vinyl. Some collect baseball cards. You collect podcasts. Let’s keep it that way. Because podcasts disappear. Episodes get pulled. Shows move. Feeds vanish. Sometimes the internet just wakes up and chooses chaos. CastKeeper was built for one simple reason: If you love a podcast, you should be able to keep it. Forever. The Internet is great… right up until your favorite episode disappears. Archive audio and video podcasts, transcripts, chapters, artwork, notes, metadata, and more to storage you control. Choose where your collection lives: • iCloud Drive • Dropbox • External USB drives • S3-compatible storage • Your own cloud When someone says, “Sorry, that episode isn’t available anymore.” You can politely smile… and press Play. We Mind Our Own Business Some apps know everything you listen to. CastKeeper would rather not … by choice. Your podcast app shouldn’t know more about you than your friends. • No account. • No ads. • No subscriptions. • No creepy tracking. Tracking Prevention helps reduce podcast analytics and tracking requests because your podcast player shouldn’t have a side hustle. Listen Smarter Need to remember something from a three-hour episode? We’ve got you. • AI summaries • Smart chapters • Searchable transcripts • Live Captions while you listen • Episode translation • Timestamped notes • Powerful search It’s almost unfair to the pause button. A Podcast Player That Actually Plays Podcasts Crazy concept, we know. • Audio and video playback. • CarPlay. • Picture in Picture. • Mini Player. • Sleep Timer. • Private sync across iPhone, iPad, and Mac. Basically everything you’d expect… plus the part where your library doesn’t randomly evaporate. Built for Everyone Great software should work for everyone. CastKeeper includes support for VoiceOver, Dynamic Type with dyslexia-friendly fonts, Live Captions, keyboard navigation, high-contrast display options, and accessibility features throughout the app—because everyone deserves to enjoy their favorite podcasts. Buy It Once. Tired of subscriptions? So are we. CastKeeper is a one-time purchase for all of your devices, including Family Sharing. • No “Premium.” • No “Premium Plus.” • No “Premium Ultra Max Podcast Infinity.” Just CastKeeper. Your podcasts. Yours forever.

You know those updates that say, “Bug fixes and performance improvements”? Yeah… this isn’t one of those. CastKeeper has been rebuilt from the ground up with a beautiful new interface, smoother navigation, richer visuals, and countless improvements throughout the app. It’s faster, cleaner, and designed to make archiving and listening to your favorite podcasts even better. Why? Because podcasts disappear. Yours don’t have to. The private sync engine has been rebuilt from scratch, making it faster and more reliable to keep your library in sync across your iPhone, iPad, and Mac—all while keeping your data private. Because your podcast app shouldn’t know more about you than your best friend does. Also new in this release… • Archive public podcast episodes directly to external storage. Plug in a USB drive or other supported storage, pick it in Settings, and start building your forever library. • New Tracking Prevention helps reduce podcast analytics and tracking requests during playback. Listen to your podcasts—not someone else’s analytics dashboard. Tell these trackers the “P” in IP doesn’t stand for public and opt-out of tracking. • Expanded Dynamic Ad Insertion (DAI) detection means smarter, cleaner AI summaries. • New Discovery themes make it even easier to find your next favorite show. • Smaller app. Smaller archives. More room for podcasts. No regrets. • Fixed Home Screen widget playback issues, improved performance, increased reliability, and generally taught CastKeeper a few new tricks. Thanks for all of your feedback, feature requests, and bug reports. They genuinely help shape every release. Your podcasts. Yours forever. CastKeeper.
