oh my, this changes everything! My siblings are always finding out my phones password and installing apps ect. and this is just the best app ever! You can customize everything from the password screen theme to making an audible warning sound when the password is entered incorrectly. You can put a custom word or phrase to recover your password if you forget. You can lock any apps and there is a lot of variables! Highly highly recommend!!

So far so good. Taking my phone to have my screen repaired, working great. *** UPDATE*** Cool. So, this doesn't work. Had my screen installed, and once the phone powered back on the app didn't activate, and ALL my apps, pictures, and social media were fully accessible when I picked up my phone. I was able to scroll through every app that was locked entirely, and it wasn't until I reopened the app that it activated, despite the setting being activated to open over apps, etc.

The ads are HORRIBLE. Just trying to set it up and each click resulted in a new ad that lasted several seconds. Ridiculous!! Also, once set up, if you click on a locked app, it actually opens the app for 1-2 seconds, and then it requests the fingerprint or pass code. So basically if someone had your phone, they could open an app for a brief second, potentially being able to see sensitive information. That defeats the purpose of locking an app to begin with. Un-installed and will not use.
