# SIM ID vs App Lock

The clearest difference is rating: App Lock at 4.5 against SIM ID's 1.5. App Lock also leads on review sentiment (58% vs 22%) and ratings volume (5.3K vs 2). SIM ID's advantage is in-app purchases (none vs 7) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. App Lock sells 6 in-app purchases, starting at $4.99 per month. SIM ID asks for nothing beyond the download.

App Lock holds the better App Store score, 4.5 against 1.5. That said, the two scores are not equally well evidenced: App Lock has 5.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 22% of SIM ID's written reviews are positive against 58% of App Lock's.

SIM ID ships an update every 2 months, App Lock fortnightly. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
