# 尺书 vs Post

The clearest difference is in-app purchases: Post at none against 尺书's 2. Post also leads on update cadence (fortnightly vs every 5 weeks). 尺书's advantage is iOS requirement (9.0 vs 13.0). On price, ads and device support there is nothing between them.

Both are free to download. 尺书 sells 1 one-off in-app purchase. Post asks for nothing beyond the download.

尺书 ships an update every 5 weeks, Post fortnightly. The most recent releases landed on October 3, 2026 and October 14, 2026 respectively.
