4 : Its a good app but there is one problem i am facing. I have locked play store so that my kids do not install any games. I have also installed and activated app lock protection. But the kids have found a way for downloading games. They just restart the phone and as soon the phone restarts they open the play store and downloads the desired games as applock starts working after around 4-5 minutes. They have also uninstalled the app lock. Pls develop something by which the phone doesn't switch off

2 : Don't get me wrong, it works. But for literal no reason it continues turning my screen black, no ad no nothing, it pops up out of nowhere. It's quite annoying. Other then that this apps pretty good.

4 : Up date: i had a complaint about the app and they responded and fixed the error. I really like this app and like that they responed so quickly. The only thing I've found now, is that when I open an app that is locked and leave on the lock screen sand later pick up my phone the app is open and the app lock screen when away. This happens after about 10 minutes. I'm using moto g6 and a moto g7. It does it on both

1 : useless it always hang many times in a day and response after open the application which I locked there is no strong privacy as it should. I am not satisfied at all. I am very angry .😣😣😣😣

FAQs & Tutorials

Q: What is an .APK File?

A: An Android Package Kit (APK for short) is the package file format used by the Android operating system for distribution and installation of mobile applications. Just like Windows (PC) systems use an .exe file for installing software, Android does the same.

Q: What is an .XAPK File?

A: XAPK is a zip format standard that includes Android App Bundles or APK files (installation packages), along with OBB, cache assets, and other data files. This format ensures that an app is downloaded and runs successfully on Android devices. Due to the Google Play Store's limitation on app file sizes, developers often use the XAPK file format for apps larger than 100MB. This approach allows users to download APK files on Android without experiencing corruption issues.

Q: How to install .APK File?

Installing APK files on Android devices is straightforward. Here's a step-by-step guide:

  1. Download the APK File: Download the APK file from this website and save it in an easy-to-find location, such as your device's 'Downloads' folder.
  2. Open and Install the APK File: Locate and open the APK file you just downloaded. A prompt will appear asking for your confirmation to install the app. Tap "Install" to proceed with the installation.
  3. Complete Installation and Launch the App: Wait for the installation process to complete. Once installed, you can open the app directly or find it in your app drawer.

Q: How to install .XAPK File?

To install an XAPK file, you need to use the Split APKs Installer (SAI) application. Here's how to do it:

  1. Install SAI: Download and install the Split APKs Installer (SAI) app. The installation process is similar to that of any regular APK file.
  2. Install the XAPK:
    - Open the Split APKs Installer (SAI) on your device.
    - In SAI, tap on the 'Install APKs/XAPK' button.
    - Navigate to the folder where you saved the downloaded XAPK file.
    - Select the XAPK file you wish to install and proceed.
  3. Complete the Installation: Follow the on-screen instructions within SAI to complete the installation process. Once the installation is finished, the app will be available in your app drawer for use.
