# Lock Notes vs MemoryAI

The clearest difference is review sentiment: MemoryAI at 100% against Lock Notes's 53%. MemoryAI also leads on in-app purchases (none vs 7) and update cadence (every 3 days vs every 10 days). Lock Notes's advantage is rating (4.4 vs 4.0) and ratings volume (138 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Lock Notes sells 7 in-app purchases, starting at $4.99 per 7 days. MemoryAI asks for nothing beyond the download.

Lock Notes holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Lock Notes has 138 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 53% of Lock Notes's written reviews are positive against 100% of MemoryAI's, so the app with the better star average is not the one people write more warmly about.

Lock Notes ships an update every 10 days, MemoryAI every 3 days. The most recent releases landed on November 11, 2026 and November 5, 2026 respectively.
