That is why we have here the best Facebook spy apps that are great if you’ve been wondering how to monitor Facebook Messenger on someone’s phone.


One of the most famous Facebook spying apps available today is Spyic. This is a spy for Messenger that can do a whole lot of other things as well. Users can remotely view the target’s Facebook Messenger activities, check the timestamps on messages, check the contact information within the chats, download any media files that were shared in a chat, and even get their hands on deleted messages. All of this is done remotely and discreetly, without the target’s knowledge.

Mobile Spy

Mobile Spy is a good spy for Messenger but it only works with Android phones. This FB spy app is also quite expensive at $64.97 for a period of three months. However, if you can look past these then Mobile Spy is a very solid Facebook spy app that can allow you to not only see Messenger activity but also view the target’s phone screen live if you want. You can also use the app’s keylogger feature to get their Facebook login details. This feature is quite excessive and should be used only with the target’s knowledge.


With Mobistealth, you can easily monitor someone’s device for various activities like calls, text messages, emails, browser usage, location, and much more. On top of all that, it’s also a Facebook tracking app that gives you access to someone’s Messenger chats. You can also view the contact information to figure out who your target is talking to. All of this is done in complete secrecy without alerting the target phone’s user. Mobistealth is also quite good when it comes to customer support. If you’re interested, Mobistealth can be yours for $69.99 per month.


mSpy is probably one of the most famous, if not the most famous, spy apps for iPhone and Android phones out there. It has a very strong reputation in terms of the features it provides and the level of support and service users get from the company. mSpy can help you track Facebook Messenger on the target device as well as track calls and text messages. You can also track the cell phone’s location, web usage, and much more with mSpy. All in all, mSpy is a great spy for Messenger as well as for a host of other activities.


Hoverwatch is yet another Facebook spy app that can also spy on many other social media and communication apps like Snapchat, WhatsApp, and Viber. This makes Hoverwatch a favorite amongst people who are looking for something beyond just a Facebook spy app. Of course, you can also use Hoverwatch for other tracking other activities as well but the strength lies in its focus on social media.

FlexiSPY is a premium mobile phone tracker that is great for phone spying in various scenarios. It’s a very popular Facebook spy app that can be used on both Android phones and iPhones.

FlexiSPY can be bought for $199 if you want the Extreme version with advanced features such as phone call interception and sending fake messages.

Auto Forward

Auto Forward is a Facebook spying app that can be used for quite a reasonable price of $29.99. However, the catch with using the Auto Forward spy app is that you will need to root the target Android device and won’t be able to use in on an iPhone. It’s definitely one of the best hidden spy apps for Android if you have the technical knowledge required for rooting the target device.

Highster Mobile

Highster Mobile is a Facebook spy that can be set up within a few minutes and is very easy to use. It also focuses on tracking popular social media apps which makes it a good choice for concerned parents around the world.

To use this mobile tracker for free though, you do need to root the target Android device. If you can manage to do that and live with a dated interface, then TheTruthSpy can be useful as a free Facebook spy app for Android. Don’t miss our TheTruthSpy review.
