# Contact Notes vs App Lock

The clearest difference is review sentiment: App Lock at 77% against Contact Notes's 0%. App Lock also leads on in-app purchases (none vs 2) and ratings volume (378 vs 1). Contact Notes's advantage is rating (5.0 vs 4.4) and update cadence (every 3 days vs every 3 weeks). On price there is nothing between them.

Both are free to download. Contact Notes sells 2 in-app purchases, starting at $2.99 per month. App Lock asks for nothing beyond the download.

Contact Notes holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: App Lock has 378 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Contact Notes's written reviews are positive against 77% of App Lock's, so the app with the better star average is not the one people write more warmly about.

Contact Notes ships an update every 3 days, App Lock every 3 weeks. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
