# Synopsia vs XAirReader

The clearest difference is update cadence: XAirReader at every 2 days against Synopsia's every 2 weeks. XAirReader also leads on rating (5.0 vs 4.6). Synopsia's advantage is ratings volume (291 vs 1) and iOS requirement (13.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Synopsia sells 4 in-app purchases, starting at $6.99 per month and XAirReader sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

XAirReader holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Synopsia has 291 ratings behind it against 1, so its average is the more settled of the two.

Synopsia ships an update every 2 weeks, XAirReader every 2 days. Both last shipped on October 31, 2026.
