    Block Websites on Android with Web Blocker Apps

    Web blocker apps are specifically designed to block websites on phones and tablets. The advantage of using them is that they block websites on your child’s device, regardless of the browser they use. Using web blockers, you don’t need to install add-ons and extensions on each and every browser your child uses. Moreover, you can let your child surf the internet with the popular Chrome browser since web blockers work well with Chrome.

    There are various web blocker apps on Google Play, but we recommend BlockSite. If you remember from the previous paragraphs, BlockSite is also a web browser extension. Below we’ll explain how to run BlockSite on your child’s Android phone or tablet.

However, some of them, like Mobile Security, also have website-blocking features. Below we’ll explain how to use Mobile Security on your child’s phone to block websites.

    Block Websites on Android Using Host File

    Host file is a plain-text file in the Android operating system that maps hostnames and IP addresses. Modifying this file can block inappropriate websites on your child’s phone or tablet. However, you should be careful since the host file is crucial for your child’s phone to operate.


    How to Edit Host Files to Block Websites on Android

    There are two methods for editing the host file: On a computer or on your child’s phone or tablet. Below we’ll explain both.


    On a Windows Computer

    1. Download SDK Platform-Tools from the Platform-tools website
    2. Install the Android Debug Bridge command-line tool on your computer to control your child’s phone or tablet via USB
    3. Connect your child’s device to your computer via the USB port
    4. Open cmd prompt and enter “adb devices”
    5. Then type “adb pull /system/etc/hosts C:\hosts” (You can replace C with the drive you wish to copy the host file to)
    6. Go to the drive you saved the host file
    7. Open the host file with Notepad
    8. Add the IP “” and the website URL you want to block. E.g. To block, type
    9. Save the host file
    10. Now use cmd prompt again to type “adb push C:\hosts /system/etc/” to return the host file to your child’s device with Android Debug Bridge. (Replace C with the drive where you saved the host file to)


    The host file opened with Notepad


    On an Android Device

    1. If you don’t already have a file manager on your child’s device, download and install a file manager app like ES File Explorer File Manager from Google Play or any other app distribution platform on your child’s Android phone or tablet

    3. Tap the / button
    4. Look up the host file

    7. Save and restart the phone for the settings to apply


    Block Websites on Android Devices with Parental Control Apps

    All the methods described so far have limitations. For example, if you block websites on Firefox, your child can still access inappropriate websites via a different browser. In addition, although web blocker apps block websites on all browsers, your child can still freely surf the internet on another device. Similarly, security apps block websites on the same device installed. Finally, modifying the host file is a difficult task which may harm the device if done wrongly.

    As an alternative, we suggest parental control apps such as Safes that work on all phones, tablets, and computers running on Android, iOS, Windows, and macOS. Safes is very user-friendly and not as complicated as the other methods. Using Safes, you can monitor and control your child’s access to the internet remotely. That means after installing Safes Kids, a Safes companion app, on your child’s devices, you don’t need to touch them again to apply restrictions.

    Say goodbye to the hassle of ineffective web blockers and hello to peace of mind with Safes. Join our community today and take the first step towards a safer online experience for your child.
