Anti Spy: Camera & Microphone Block

The thought of being watched (and, therefore, controlled) by other people scares most of us. However, not everybody knows how to fight this kind of thing. Well, it’s not hard, you don’t even need to write code or understand how the Internet security should work. 

One thing that makes the app so cool is that it can find and fight viral trojans, which is great if you often download files and programs from the Internet. 

Some other features will come in handy once you download the app:

  • Camera and microphone blocker. These options are used by most people who are concerned about their privacy. That’s logical – your micro should be turned on only when you need it. If you are not talking to someone, why the micro should be turned on? To let the hacker listen to you? 
  • Security Alerts. If you were asleep and the hacker tried to use your device’s camera when you have no control of your device, Antispy will tell you about it. 
  • Fake location. Sometimes you don’t want to be located by your device’s GPS. That’s pretty normal. In this case, you can set a fake location. It works like a VPN when you’re using a browser. You can choose an exact location or use the random one. 
  • See the history of your camera/micro usage. The app collects statistics on that so you can easily get a graph reflecting the time when your camera or microphone was used (it doesn’t matter if it was you or not; the app just reflects the usage). 
  • Create a widget to place it on your home screen and get fast access to the micro or camera. 
  • Set alerts to know when exactly the micro is being used. You will get notifications. 
  • Access scanner. This powerful tool will help you find the apps that have access to the microphone and camera. 

To help the app function properly, give it the Device Administrator permission. It is safe. 

Please note that the application doesn’t work properly on every device. If you find glitches, contact the developers via email. They are fast to react.

1Blocker allows users to safely visit multiple websites on Safari, as it blocks the intrusive ads, in-app trackers, or other irritating elements on the websites.

First of all, we would like to mention that 1Blocker is a safe and reliable application, as it does not track your activity. What is more, there is a function of blocking the camera and microphone.

After downloading the app, you will be transferred to the menu page straight away. Here you will find the following sections:

  • Safari
  • Firewall
  • News
  • Settings

Users can enable the blocking option just in a few clicks. Moreover, you can monitor all the blocked resources on a website.

Safari knows in advance what should be blocked and does it itself. Therefore, due to this app, all the websites will be loaded much faster.

Speaking of additional features, the application also enables you to block the integrated microphone, URL, cookies, etc. Plus, you can hide any element by CSS as well.

The application comes with both free and paid versions. However, if you use a free version, you will gain access to only one category of blocking.

The developer warns that the app can’t block all types of ads, as some websites use special techniques to prevent the blocking process.

Microphone Blocker

This app is a must if you care about your privacy and security online. You might know that the browser you’re using or the apps on your phone can be collecting data about you via the microphone. This information might be sold to other people or companies. You don’t want this to happen, do you?

  • GPS usage scanner. The app will tell you if any website is trying to track your location so that you could do something with this.
  • Make your Bluetooth invisible. This measure can also make you safe. We recommend that you don’t leave your Bluetooth turned on if you don’t need it.
