I'm a premium user. I've been using it for two years. After reading many other reviews here. I can see that many people are not configuring the app correctly. AppLock must be set with Device Admin permissions. It must be allowed to draw over other apps. It must be set as a home launcher. If you set it up right, you will not be able to bypass the screen lock. Yes, the screen draw does not obfuscate some notifications nor apps in multi task view. Its job is to stop wanted access not conceal data.

So far I like the app a lot but haven't had it long! I feel like you can block some good bypasses by being able to lock settings and pretty much everything. Also so far, when I reset my note 20 ultra, it takes like 10 seconds to load but there is a delay on the lock for the apps but does eventually pop up. For my phone, everything else pops up as locked instantly after initial startup. For the screen repair place having full access to my phone, I've locked everything. So far this is good for me!

The best app locker ever! I've tried many other apps and even made a tasker task to lock apps and this app easily beats all of them. The problem with other apps is that you can bypass the lock with multitasking (it moves the lock screen to one side of the screen and gives access to the locked app on the other side). This app will lock that process, so if you try to multitask,it brings up the lock screen instead. It also locks and prevents app uninstalls, which other apps don't do. 5 stars!
