# Study Bible Reference vs ZTF Books

The clearest difference is rating: ZTF Books at 5.0 against Study Bible Reference's 3.7. ZTF Books also leads on update cadence (every 2 days vs fortnightly). Study Bible Reference's advantage is in-app purchases (none vs 3). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. ZTF Books sells 3 one-off in-app purchases. Study Bible Reference asks for nothing beyond the download.

ZTF Books holds the better App Store score, 5.0 against 3.7. Both are backed by a comparable volume of ratings — 3 and 4 respectively. Written reviews complicate that: 67% of Study Bible Reference's written reviews are positive against 63% of ZTF Books's, so the app with the better star average is not the one people write more warmly about.

Study Bible Reference ships an update fortnightly, ZTF Books every 2 days. The most recent releases landed on November 7, 2026 and November 6, 2026 respectively.
