Read CBZ and CBR comics and manga, with two-page spreads, double-tap zoom, and a reading direction you set per book. Listen to audiobooks with chapters, a sleep timer, Car Mode, and CarPlay. Or follow along with EPUB 3 narration, where the text highlights in time with the voice. READ ALOUD Any book can be read to you, by any Apple voice on your device or by natural neural voices in 31 languages that you download once and then run offline. The sentence highlights as it is spoken and the pages turn on their own, with speed presets, sentence skips, a sleep timer, and Lock Screen controls. Prepare a book in advance and keep listening with the screen off. TYPOGRAPHY YOU CONTROL 200+ fonts, or import your own. Tune size, weight, line and paragraph spacing, alignment, hyphenation, and separate margins for portrait and landscape. Save settings per book so a novel, a textbook, and poetry each look right. Build your own color themes and let them switch at sunset. Choose which buttons the reader toolbar shows and where a tap opens it, and give links their own color and style. Smart dark mode keeps images natural, and in-reader brightness, Line Focus, and eye-care break reminders protect your eyes.

Verdict
The clearest difference is rating: BookVault at 5.0 against EPUB Reader's 4.6. EPUB Reader's advantage is ratings volume (55 vs 1) and update cadence (every 5 days vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. EPUB Reader sells 3 in-app purchases, starting at $4.99 per month and BookVault sells 2 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.
BookVault holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: EPUB Reader has 55 ratings behind it against 1, so its average is the more settled of the two.
EPUB Reader ships an update every 5 days, BookVault every 2 weeks. The most recent releases landed on October 31, 2026 and October 28, 2026 respectively.
