# 文庫 vs 青空文庫

The clearest difference is in-app purchases: 文庫 at none against 青空文庫's 3. 文庫 also leads on ads (none vs shown). 青空文庫's advantage is update cadence (weekly vs every 4 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 青空文庫 sells 3 in-app purchases, starting at $0.49 per month. 文庫 asks for nothing beyond the download.

文庫 ships an update every 4 months, 青空文庫 weekly. The most recent releases landed on October 10, 2026 and October 29, 2026 respectively.
