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)

Beware if you are paying for the "one year premium". It's a trick! They want you to think that you pay $54.00 per year, but they charge you every month! By the time most people find out that it is a monthly charge, Applock pro has already swindled them out of $108.00! It is non-refundable, and an expensive mistake. Beside the deceitful trick, the app doesn't even work. many times without warning, locked apps will open without a pin. It is very unreliable, and very frustrating.

I would say this app is an okay app. It's very simple and easy to set up and use. My only issue with it is a big deal, and that's that there's a lot of time a delay in the time the app lock actually works. For example, someone can open one of your apps and actually see and read your messages/information for 5 to seven seconds before that particular app is closed and the App Lock Pro screen appears. That could improve with an update possibly but for now it's a real security risk and vulnerabilit
