It works pretty well and I didn't have many issues. The only problem I had was with the fake cover that tells you the app stopped working. I would always get an ad before getting a chance to get passed that screen which kind of defeats the whole purpose since it announces that you're using an app lock. It also didn't always register when I was holding the button to get off of that screen. Other than the fake cover feature, I haven't had any issues and the app works really well.

Overall good. The only thing I find to be a major problem (at least for me) is that it automatically allows fingerprint passcode no matter what your settings are. There is no way to turn it off. I am not the only one with a thumbprint saved to this phone but I don't want them going on specific apps that's why I wanted an app lock. When they fix that problem I will redownload.

One small problem. If you are opening a locked app and select "Forgot Pattern", it exposes the locked app as it changes to the "Enter Pin" screen. I suppose this isn't a major issue for most people, but if you are locking an app that you would prefer not to be exposed, whomever is attempting to unlock it will be able to see what you were working on.
