Ondelia plays the audiobooks you already own. No store, no subscription, no account: import your files and they stay on your devices. YOUR FILES, YOUR LIBRARY Import a file, a whole folder or a ZIP from Files or over AirDrop. Ondelia reads embedded chapters and CUE files, picks up cover art and duration, and rebuilds series. LISTEN ON APPLE WATCH, WITHOUT YOUR IPHONE Send the current chapter and the next ones to the watch: playback is local, with no phone and no signal. The watch keeps its buffer topped up, and your position finds its way back to the iPhone. A SERIOUS PLAYER Per-book speed, custom skip intervals, smart rewind after a pause, one tap back to where you were before a bad scrub, bookmarks, a play queue, and a sleep timer with fade-out or end-of-chapter. TEXT THAT FOLLOWS THE VOICE On-device transcription: the text scrolls with the narration, and tapping a sentence jumps there. EVERYWHERE IN IOS iPhone and Apple Watch widgets, Siri shortcuts, Lock Screen and AirPods controls complete with CarPlay. NOTHING LEAVES YOUR DEVICES No account necessary, no ads, no analytics, no profile. Positions, bookmarks and finished state sync through your own private iCloud, and can be turned off in one tap. Your audio files are never uploaded anywhere. ENHANCED WITH HARDCOVER Use Hardcover to get metadata, track your progress and the book you've read, automatically create book series.

Verdict
The clearest difference is in-app purchases: Ondelia at none against Hardcover.app's 2. Ondelia also leads on update cadence (every 3 days vs every 6 months). Hardcover.app's advantage is iOS requirement (15.0 vs 26.0). On price, ads and device support there is nothing between them.
