# BookJacked vs Sophia

The clearest difference is ratings volume: Sophia at 137 against BookJacked's 1. Sophia also leads on update cadence (every 6 days vs fortnightly). BookJacked's advantage is rating (5.0 vs 4.7) and iOS requirement (16.6 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. BookJacked sells 5 one-off in-app purchases and Sophia sells 13 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

BookJacked holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sophia has 137 ratings behind it against 1, so its average is the more settled of the two.

BookJacked ships an update fortnightly, Sophia every 6 days. The most recent releases landed on October 21, 2026 and October 25, 2026 respectively.
