# Calibre View vs Sutra

The clearest difference is rating: Calibre View at 5.0 against Sutra's 4.4. Calibre View also leads on in-app purchases (none vs 4). Sutra's advantage is update cadence (weekly vs every 6 weeks) and review sentiment (85% vs 67%). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Sutra sells 4 one-off in-app purchases. Calibre View asks for nothing beyond the download.

Calibre View holds the better App Store score, 5.0 against 4.4. Both are backed by a comparable volume of ratings — 4 and 14 respectively. Written reviews complicate that: 67% of Calibre View's written reviews are positive against 85% of Sutra'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, Sutra weekly. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
