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 in-app purchases: Calibre View at none against EPUB Reader's 7. Calibre View also leads on rating (5.0 vs 4.7). EPUB Reader's advantage is update cadence (every 5 days vs every 6 weeks) and review sentiment (89% vs 67%). On price, ads and device support 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 7 in-app purchases, starting at $2.99 per month. Calibre View asks for nothing beyond the download.
Calibre View holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: EPUB Reader has 36 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of Calibre View's written reviews are positive against 89% of EPUB Reader's, so the app with the better star average is not the one people write more warmly about.
Calibre View ships an update every 6 weeks, EPUB Reader every 5 days. The most recent releases landed on September 20, 2026 and September 23, 2026 respectively.
