Hello! Im using your paid version. Your newest update is really terrible, it crashes my phone, playstore en package installer. And the pop-ups are terrible. It also prevents my phone from rotating while I'm using maps. When I start my car with the phone plugged it. The popup comes up, and hinders the rotation function off the screen. Really terrible app. I will not use it again and I am VERY dissatisfied.

Awesome app! It's definitely free and easy to use (despite the premium version)! Definitely recommend it. Though, I only wish to have more fake app icons OR be able to upload one and change the name, as well as more natural fake error messages (an error message that looks like a standard error message depending on phone model)

Nice app. Only 1 problem, it doesn't work! The lock is very easily bypassed with the recent apps software button on android 13. When the lock kicks in just keep tapping that button and it will show the recent apps from where you can go to settings and remove applock pro. Or select anything else from the recent apps and the lock won't even kick in at all anymore after that. Pretty much all applock applications suck. There's only 1 that's working good and that's the native one.
