works as advertised, but slows down your device considerably (doogee S41 pro). I uninstalled it after a few days and performance was normal again .

This app is one of the worst app in the Field of smart phone. Once it is activated then fingerprint option doesn't work. So, what is the use of such app. I request all of you not to install this app.

Giving device admin will give a complete control over your phone!!! They can remotely do anything with your phone even sending sms,email etc!! Don't install!!! Other locking apps does not require device admin privilege!!!!be smart,even google can't check all apps available on Google play for spyware!!!

Warning: Seems like malware. After I did everything the app asked including giving it admin privileges, I didn't see the app in the list of widgets to put on the homepage. Tried to uninstall the app, but the play store app just couldn't. Finally, I had to go to the phone settings, search for the app, FORCE STOP it, CLEAR STORAGE, and then uninstalled the app in the settings app itself.

I don't know what some of these reviewers are complaining about… My last phone, a Samsung Galaxy let me add a "screen off" button to the system buttons at the bottom of the screen. Since I can't do that on my new Google phone, I added this simple app, which works beautifully. I don't usually use a password or other lock method (it's unnecessary, as my phone's never where others can access it), so that may simplify things—but in any case, I'm grateful for the app! Thanks!

I wonder why it forces me to unlock it via password, instead of fingerprint, if I lock it with this app.

The app forces me to enter the 4 digit code every time. I used to be able to use a finger print. I see you're still working on this app, so why don't you address the issue I've reported?

I benefit a lot from this app; this app helps me secure my phone. Because of this app, I secure my mobile when I am about to sleep. Before going to sleep, I lock my mobile using this app. When the mobile is locked through this app, the fingerprint feature doesn't work. The advantage of this is that while sleeping, no one can unlock my mobile by touching my finger. When trying to unlock with the fingerprint, it says 'Device is locked by Admin.' This is a very good feature, and I really like this

It appears that this app is a spy application collecting user data through the "Usage access" settings. Other apps in this category did not require me to enable "Usage access," yet this app does. Additionally, it is accessing the internet, which suggests it is sending user data to external servers, and this is unacceptable. I urge Google to remove this app from the Play Store and strongly advise users to uninstall it immediately.
