# Chapters vs Sync

The clearest difference is review sentiment: Sync at 100% against Chapters's 33%. Sync also leads on update cadence (every 5 days vs every 7 months) and price ($4.99 vs $9.99). Chapters's advantage is device support (4 vs 2) and iOS requirement (15.0 vs 18.0). On ads, in-app purchases and monetization model there is nothing between them.

Chapters ships an update every 7 months, Sync every 5 days. The most recent releases landed on October 2, 2026 and October 14, 2026 respectively.
