# 密码本 vs 超级私密笔记

The clearest difference is update cadence: 超级私密笔记 at every 2 months against 密码本's every 12 months. 密码本's advantage is iOS requirement (10.0 vs 12.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

密码本 ships an update every 12 months, 超级私密笔记 every 2 months. Both last shipped on November 3, 2026.
