requires following permissions on your android device.

approximate location (network-based)
Allows the app to get your approximate location. This location is derived by location services using network location sources such as cell towers and Wi-Fi. These location services must be turned on and available to your device for the app to use them. Apps may use this to determine approximately where you are.

precise location (GPS and network-based)
Allows the app to get your precise location using the Global Positioning System (GPS) or network location sources such as cell towers and Wi-Fi. These location services must be turned on and available to your device for the app to use them. Apps may use this to determine where you are, and may consume additional battery power.

view network connections

view Wi-Fi connections
Allows the app to view information about Wi-Fi networking, such as whether Wi-Fi is enabled and name of connected Wi-Fi devices.

  1. Sri ram-avatar

    The unknown caller cover didn't work on the one plus 6. I install the app only because of this feature which in the end didn't work. The Green and Red buttons were out of the screen that I couldn't see them.

  2. farooq Sayeed-avatar

    In beginning it works great. It's ok to show ads but later on I am facing lot of problem I couldn't launch an application as soon as I launch it shows ad and goes back. Try to fix this.

  3. Vishal Kunvarani-avatar

    It was great to use this app and I want to say that please don't believe on the reviews of others because now this app has reduced its ads. I really love this app. Please install it to get your good experience.

  4. Johnny Wheatley-avatar

    Johnny Wheatley


    It definitely helps keeps my apps secured. I have tried almost every no root locking app in play store and so far only found 3 that works for me. Out of the three this is on the bottom of that list.

  5. Aby Johnson-avatar

    This app is good but it more permits than the normal app lock have. Why a app lock need our location? which and all other which means this app is collecting our information stay alert all the app lock users. never share your location at any costs.

    Sk Golam Mursid


    Good app but only problem is that sometimes it goes stop working. Solve it as soon as possible.

  7. Wilson-avatar

    The previous version were better and had hiding feature too. The new version is not working like previous ones. Not happy with the new update

  8. J-avatar

    In all these locking apps if we directly uninstall the app from outside then the locking app uninstalls without asking any password or pattern....by this anyone could access to our apps easily by just uninstalling this app....ao it provides actually no security....so what is the benefit of using it......plz provite better security

  9. A Google user-avatar

    Features are good but you should remove the mandatory permission access to location, phonecalls & contacts. file acces permission is ok.
