# Lock Notes vs 极简密码本

The clearest difference is rating: Lock Notes at 4.5 against 极简密码本's 2.0. Lock Notes also leads on ads (none vs shown) and update cadence (every 10 days vs every 2 months). 极简密码本's advantage is monetization model (free with in-app purchases vs subscription). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Lock Notes sells 3 in-app purchases, starting at $14.99 per year and 极简密码本 sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Lock Notes holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: Lock Notes has 1.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 73% of Lock Notes's written reviews are positive against 68% of 极简密码本's.

Lock Notes ships an update every 10 days, 极简密码本 every 2 months. The most recent releases landed on September 26, 2026 and September 20, 2026 respectively.
