Your phone might have years of text messages and emails with personal information, saved voicemails, pictures of your family, GPS location data, browsing history, notes and more. It’s a record of your entire life wrapped in a bit of metal, plastic and glass. Imagine how terrible it would be for a snoop to get their hands on that information. If someone you know seems to know a little too much about your life, they could be spying on you right now. While we are telling you about these apps, it’s strictly for you to know what is out there. If you install any of these apps, do so at your own risk. Be forewarned that these apps are not legal in certain states.

1. TheOneSpy

If you use an iPhone or iPad, then you need to watch out for TheOneSpy. It’s a unique app that specifically targets gadgets that run on iOS, and it’s scary. Once the software is installed, whoever installed it is essentially in possession of everything that happens on that particular device. All of the data collected by TheOneSpy is encrypted and sent to a web portal where a spy can review it. This means someone could be reading your sent and received text messages and emails, listening to recordings of your phone calls, snooping through your browsing history and more. TheOneSpy can also activate the microphone and camera on your device to spy on your surroundings. A subscription plan for TheOneSpy isn’t all that expensive. At least, not when you compare it to others out there. Purchasing 30 days of monitoring only costs around $25.

2. Highster Mobile

This spying software is known for its ability to monitor other apps you use on your device, such as Facebook, Instagram, Skype, WhatsApp, etc. It can be installed remotely, and can block any app it’s told to. And you might think that you can cover your tracks, but you’re wrong. Highster Mobile has the ability to access messages and data that have been deleted. Highster Mobile can also be used to completely lock a targeted phone, which means you could lose access to your device entirely. It works on both Apple and Android devices, and only costs a one-time fee of $70 to purchase the software.

3. FlexiSpy

Similar to the others mentioned above, FlexiSpy is an app that can be installed on your device to spy on activity. It shares many of the same features but gets worse. Not only can FlexiSpy monitor messages, audio and data, it can spy on your GPS location, passwords, and other apps. Plus, whoever installed the app can receive alerts for various triggers, and can spy on you in secret since the application is hidden from the task manager. Premium plans for FlexiSpy cost $68 per month, and the app can be used to monitor both Android and Apple smartphones and tablets.

4. mSpy

If someone is paranoid enough to spy on you, they might be using mSpy. One of the most frightening things about mSpy is its ability to monitor content from apps like SnapChat. It can also monitor your GPS location, and even restrict incoming calls from a predefined number. mSpy is marketed toward parents who are worried about their child being contacted by someone they don’t trust, and it’s perfectly legal. However, it is possible that the software could be installed by an untrusting spouse or employer who has access to your device. Plus, mSpy offers 24/7 customer support to help these spies find what they need. Worried yet? It gets worse. mSpy also has a bundle kit that provides desktop monitoring too. This means that every device you access could be used to spy on you. And this bundle kit costs less than $20 monthly.

5. Spyera

Now, this is freaky. Spyera isn’t just an app, it’s an entire smartphone. The app comes pre-installed on various Apple and Android devices, so whoever gives you the phone could be monitoring all of your personal activity. Spyera software can listen in on phone calls and can use your microphone to listen in on everything else that’s happening near the smartphone. It can even record this audio as it’s happening and store it for later. If that’s not enough to make you shiver, Spyera can also track your instant messages and texts, upload copies of the photos you take, spy on conversations held through other apps like Skype, Viber, WeChat, etc., log everything you type, and even use the camera to spy on you physically. Perhaps the only thing about Spyera that might bring you comfort is that it’s pretty expensive. Anyone who wants to spy on you using Spyera would have to provide the device to have the software installed, and pay a hefty subscription on top of that. To give you an idea, one year of spying costs $389 for a smartphone alone.
