# Reading Savings vs 1行日記

The clearest difference is in-app purchases: 1行日記 at none against Reading Savings's 1. 1行日記 also leads on update cadence (every 3 days vs weekly). Reading Savings's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18.5). On price and ads there is nothing between them.

Both are free to download. Reading Savings sells 1 one-off in-app purchase. 1行日記 asks for nothing beyond the download.

Reading Savings ships an update weekly, 1行日記 every 3 days. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
