Review summary

Users praise App Locker for its effective and simple app protection, absence of ads, and its fingerprint unlock feature. It closes common security loopholes, making it one of the better applocks available. However, multiple users report that locked apps' content can still be seen on the recent apps screen, which is a significant privacy flaw. Other common complaints include inability to lock some system apps, no protection against uninstalling the app itself, occasional problems with biometrics, and missing advanced features like intruder snapshots.

Pros

Effectively protects apps and restricts access, including closing common loopholes like phone Settings and Accessibility options.
Simple, easy to use, and has a clean, beautiful interface without ads.
Supports fingerprint unlocking as a security feature (recently added).
Allows users to control app locking frequency and has variable password length options.
Works well for parental control to restrict children's access to certain apps.

Cons

Content of locked apps is still visible on the recent apps screen, posing a privacy risk and requiring a fix.
Cannot lock certain system apps such as package installer and quickstep launcher.
Does not prevent the app itself from being uninstalled, limiting security effectiveness.
Some issues with biometric authentication errors (too many attempts) and occasional repeated pattern entry needed to unlock.
Lacks some advanced features like intruder photo snapshots and compatibility issues with secure startup due to use of Accessibility services.

2023-07-17	As*****	Just downloaded app. It seems good so far except that it shows the content of a locked app on the most recents screen. Please fix for this is an important detail. If I lock my fb messenger app and go about my day and forget to close out the screen it can be viewed from the most recents screen. If you get what I'm saying.

2023-02-10	Jo*****	This is one of only a couple applocks that I know of that closes loopholes (like a lock on phone Settings AND Accessibility). I've tried more than 20 applocks looking for something that works. For me, this is one of the best.

2022-07-04	Pa*****	This is the best App locker I've tried by far. Simple and easy to use on Samsung A53 running OS 12 with One UI ⭐ Important to remember that you must turn off in app notifications so App locker can't be disabled in notification shade ⭐ Will review again and consider donating after I've been using the app for a while.

2021-05-05	Kl*****	Finally added fingerprint unlock but still lacks intruder photo snapshot. Relatively expensive for what it does. Developer is responsive.
