# BookFolder vs XAirReader

The clearest difference is in-app purchases: BookFolder at none against XAirReader's 1. BookFolder also leads on ratings volume (30 vs 1) and iOS requirement (14.0 vs 18.0). XAirReader's advantage is rating (5.0 vs 4.7) and update cadence (every 2 days vs every 6 days). On price, ads and device support there is nothing between them.

Both are free to download. XAirReader sells 1 one-off in-app purchase. BookFolder asks for nothing beyond the download.

XAirReader holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: BookFolder has 30 ratings behind it against 1, so its average is the more settled of the two.

BookFolder ships an update every 6 days, XAirReader every 2 days. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
