Comments on Smart AppLock: Privacy Protect for Android
★★★★★Duncan Campbell· May 21, 2026
Excellent app and gives 100% safety, though the latest version has caused an issue on my android phone. Whenever I use the junk cleaner option the green button to perform the cleaning has somehow moved further down the screen. In order to use the cleaning button I have to go to the phones settings and temporarily turn off the 3 button navigation! This I didn't have to do before.
★★★★★Anton Yordanov· Jul 17, 2025
Helps me lock all my apps which I don't want someone else to use without my permission. Easy to use. Stays in the background as a process, so it's draining your battery more or less.
★★★★★Ibisa Beresiri· Dec 8, 2025
A great app, that helps me protect my phone.
★★★★☆Lemon Blossom· Jun 7, 2025
Please do an update to this app...the intruder alert when password entered wrong and picture is taken has stopped working other than that the app is good use.

This used to be a great app. It's stopped cleaning. Runs the freezes. Uninstalled and installed again. Now it freezes as I try to set up a swipe code
★☆☆☆☆Israr Ahmad Khan· Nov 6, 2025
Developers of this app died long ago. App can be uninstalled anytime if a person finds your phone unlocked and wants to see your locked apps. They'll just have to tap, hold, and uninstall the app, and all your locked apps will be open for them. There should be protection from the main settings locked by this app, and it should be able to prevent unauthorized uninstallation.
