I know I'm sounding cliché but I have, in fact, tried a lot (not all) of app lockers and this one is the real deal. What I like most about it is how seamless it is, how invisible it is until it's needed, how quickly it disappears again and of course how well it works and the level of security provided. The UI is nice, plenty of features that are useful and not bloat and simply does it's job superbly. 5 stars and would award 6 or 7 if provided.

I've literally just installed the app so I really haven't had the chance to experience it fully yet! I do not like that the intruder is able to put the wrong code/pattern in a minimum of 3 times before it takes a picture of them...I think it should be as little failed attempts as 1 if that's what the user wants! Plus I think we should be able to use both pin and code for security and not have to choose between the 2!

The main advantage of the app is its speed. It can locks an app very fast without delay ,this is very important because someone can't see the content of the app even for a sec. It is very simple app. It lacks an on/off widget which would be very convenient. It has no option for notification protection. It can not protect multitasking . Samsung Note 9 Pie
