FAQ:
• How if I forget the lock screen?
Because this app doesn't want to use Internet access (for your privacy), so it doesn't support password recovery via internet such as email.
If you forget password, you can clear app data or re-install app.
But if you activated the device admin and also locked Settings app, you will no longer be able to clear app data or uninstall app.
So please try to not forget the password!

• Why can't I activate App Locker again after force stop?
If you can't activate App Locker after already turned on the accessibility service for App Locker, then please try to turn off the accessibility service and turn it on again.

This is a great app. I only gave four stars because of an issue I have been experiencing. Sometimes one app will open another app on your phone. For example if I go to my call app and touch text messaging it will open the text messaging app to text a person that I was going to call. The applocker will unlock the first app but when it's time for the second app to open up it will not work. It becomes necessary to close everything and reopen the second app after.

Getting error: "Couldn't use biometrics (Too many attempts, try lock instead)". Set "Reset Lock timers" from app but still getting the error. Tried restarting the app too but still the same issue. Please help.

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.

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.

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.
