# App Lock vs Q R Code Reader Scan ™

The clearest difference is ads: App Lock at none against Q R Code Reader Scan ™'s shown. App Lock also leads on update cadence (every 5 weeks vs every 9 months) and rating (4.9 vs 4.7). Q R Code Reader Scan ™'s advantage is review sentiment (100% vs 67%). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. App Lock sells 2 in-app purchases, starting at $2.99 per 7 days and Q R Code Reader Scan ™ sells 4 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

App Lock holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 22 and 57 respectively. Written reviews complicate that: 67% of App Lock's written reviews are positive against 100% of Q R Code Reader Scan ™'s, so the app with the better star average is not the one people write more warmly about.

App Lock ships an update every 5 weeks, Q R Code Reader Scan ™ every 9 months. Both last shipped on October 7, 2026.
