# SwiftReader vs Zen

The clearest difference is in-app purchases: SwiftReader at none against Zen's 10. Zen's advantage is update cadence (every 11 days vs monthly) and iOS requirement (16.4 vs 18.2). On price, ads and device support there is nothing between them.

Both are free to download. Zen sells 10 in-app purchases, starting at $0.29 per month. SwiftReader asks for nothing beyond the download.

SwiftReader ships an update monthly, Zen every 11 days. The most recent releases landed on October 31, 2026 and November 8, 2026 respectively.
