Part 1: Neatspy – Editor’s Choice

Neatspy is one of the safest and most reliable Facebook Messenger Spy Apps in the market. This is because it has a vast brand identity and a sterling reputation. As such you can trust Neatspy with something as discreet as spying on Facebook messages.

Furthermore, Neatspy also has a more multi-pronged approach to spying on Facebook messages. If you aren’t content with simply observing the Facebook feed, but rather want to control it, then you need the target’s account password.

With a feature called Keylogging, you can find that out. Keylogging is a feature that registers all the keys being pressed by the target, so you can use that information to find out the password! And voila! You now have complete access of the target’s Facebook Messenger.  Check more best Android keyloggers here >>

Most Attractive Features (Other than Facebook Messenger Monitoring)

  • No-Jailbreak Option: Neatspy has a lot of other features you can access that doesn’t require jailbreaking. You can access call logs, text message logs, browser history, and perform other regular spy functions without jailbreaking. However, to avail of the no-jailbreak version, you’ll need the target’s iCloud credentials.
  • GPS Location Tracking and Geo-Fencing: Neatspy has a very powerful and accurate GPS tracker which also comes with a geo-finding feature so that you can be notified whenever the target phone goes past a preset radius.
  • No root for all social app monitoring: To monitor social app texting, you don’t need to root the target device. This is one of Neatspy’s most advanced and unique feature that other spy apps don’t have.

You can find out more about the Neatspy’s features here >

Because it comes highly acclaimed from various trusted establishments and sources, and in addition to that it has some great features at a reasonable price. It is also likely to go down well with people who aren’t tech-savvy, as they provide 24/7/365 customer service.


  • iPhone (no-jailbreak): All iOS versions
  • Android: OS 4+
  • Windows: XP; Vista; 7; 8; 8.1; 10
  • Mac: OS 10.7 Lion; OS X 10.8 – OS X 10.11 El Capitan.

Part 2: Minspy – Editor’s Choice

Minspy is without a doubt the most powerful Facebook Monitoring Spy App in the market. It can help you do a number of cool things:

minspy box

  • Read all sent/received messages, either on groups or individually.
  • View and access the profiles of everyone in the target’s friend list and thus find out about everyone they chat with.
  • Access to all the different videos, photos, etc, exchanged over Facebook or posted anywhere at all. >>

These powerful features are particularly helpful for parents who want to secretly monitor their children, but haven’t been added as friends by their kids (as kids often do.)

If you want to actively engage in the target’s Facebook, and if you want to actively access it, then you can use the Password Cracker feature which allows you to find out the target’s account passwords. Using the password you can then log into the account as that person whenever you want.

However, you should know that Minspy can only monitor phones that are jailbroken or rooted. You have to then manually install the app into the target phone. Minspy is very discreet so you can easily hide the Cydia or SuperUser icons (for iOS and Android, respectively) so the target individual doesn’t find out their phone has been tampered with.

Most Attractive Features (Other than Facebook Messenger Tracking)

  • Call Interception and Recording: You can secretly listen to conversations as they happen live, and you can even record the target’s conversations and listen to them later. However, be careful while using these features as many countries and states have made non-consensual phone tapping illegal.
  • Ambient Listening: You can remotely activate the target phone’s microphone and listen to the target’s surroundings and conversations live.

Why Minspy is this the Editor’s choice?

Because it’s the ONLY Facebook Hacker app that allows you to directly crack and decrypt the account’s password without any hassles. It also has the most powerful features in the industry.

If your interest is to purely spy on Facebook remotely, then use another app because this is extremely expensive. However, if you want the password directly, this is ideal, if you can afford it.


  • Android: till Android OS 6.0.1
  • iPhone: till iOS 9.1
  • Blackberry: till 7.1
  • Nokia Symbian: both Anna and Belle platforms
  • Windows: 7, 8, 8.1, and 10
  • Mac: OS X Mavericks, OS X Yosemite, and OS X El Capitan


If you just want to passively monitor Facebook messages, then Premium is good enough. However, if you want access to the Password Cracker feature, you’ll need the Extreme package.

Part 3: Spyine – iPhone Keylogger

Spyine isn’t exactly a Facebook Messenger Monitoring App, however it is one of the best Keylogger apps in the market and as such it can be used to spy on Facebook as well.spyine box

With the Keylogging feature, you can find out the Facebook account password and then use it to access the target’s Facebook account and find out all you need to know.

The app also takes periodic screenshots of the target phone and sends it to you, so you get a visual history of what’s been done and accessed on Facebook.

Most Attractive Features (Other than Facebook App Monitoring)

3-Day Trial Period: Because Spyine is primarily a Keylogger, it doesn't have the kind of heavy and powerful features that other apps in this list have. However, it does offer a 3 day trial period which is enough for you to decide whether this is something you want to continue with.

Part 4: TheTruthSpy - Powerful Features, but Generally Deemed as Fraudulent

TheTruthSpy is one of the most powerful Facebook Messenger spy apps for iOS and Android phones.  With Truth Spy you can perform a lot of discreet spy operation on a target's Facebook account, such as:

  • View all their Facebook Messenger conversations.
  • Find out who they have been most actively interacting with.
  • Monitor when certain conversations occurred.
  • Access all multimedia exchanged between the target and their friends.

In addition to these, TheTruthSpy also has a lot of other great features. However, you should know that it also has terrible reviews. And by terrible, I mean really terrible, awful reviews. Many users complained that the features don’t work properly, whereas others complained that even though they paid for a 3 months license, they only got 1 month, without any refund.

As such, I'm doing my duty by telling you about these different Facebook Messenger Monitoring Apps, but please approach this with extreme caution.

Most Attractive Features (Other than Facebook Messenger Monitoring)

  • Free Trial: You get a 48 hour trial period ahead of the purchase. If you really like this app then try out the Trial, and if you don’t like it, get something else.
  • Ambient Listening: Through the microphone, you can listen to the surroundings.
  • Call Recording: You can record phone conversations between the target individual and anyone else discreetly.


  • iPhone/ iPad: iOS 4.x to 7.1.2
  • Android: 2.2 to 5.x

All iPhones and Android phones need to be Jailbroken or Rooted for this app.


You can monitor up to 3 devices in all the different packages, however if you want to use it as a Facebook Messenger Monitoring App, then you need to purchase the Premium or the Gold Package.

Part 5: Mobile Spy - Non-Discreet Facebook Messenger Spy App

Mobile Spy is a really powerful Facebook Messenger Monitoring App that can be used to monitor all the channels of communication over Facebook or any other social networking site or app as well.

In addition to that, it also has a features called LIVE Control Panel, with which you can see exactly what is happening in the target phone live. Every time the screen of the phone changes, you get an update and you can see the screen yourself. As such, you can see whatever the target person is doing on Facebook and you can view text conversations over Facebook Messenger live.

However, this app can only be used by parents and that to with their permission because an icon comes on the target phone and you can’t remove it. So this can’t be used as a ‘spy’ app.

Most Attractive Features (Other than Facebook Messenger Monitoring)

  • Ambient Recording: Listen to the surroundings of the target phone through the microphone.
  • Stealth Camera: Take pictures of the surroundings with the phone camera.
  • Lockdown Mode: If you don’t want your children to use the phone at certain hours of the day, you can put it in lockdown mode.

Part 6: MobiStealth - Powerful Parental Control App

Mobistealth isn't a very focused Facebook Messenger Monitoring App, but it has some powerful features. While it doesn't offer you the option of directly being able to track Facebook messages, it has other features which can be used to help you monitor Facebook.

Mobistealth can be used as a powerful Keylogger, so that you can find out all the keys being pressed by the target, thus revealing the Facebook password as well. This can then be used to log into the target's Facebook account and either views its activities discreetly, or actively participate in it, or even hijack it by changing the password!

In addition to that, you also have access to a feature to take periodic screenshots of the phone and be sent the results via eMail. So you can find out what the target does over Facebook via the screenshots as well.

Most Attractive Features (Other than Facebook Messenger Monitoring)

  • Data Wipe: You can remotely wipe out all the data from the target phone.
  • Lockdown: You can select which hours of the day to put the phone into lockdown mode. This isn’t a very discreet feature and the target person will immediately know their phone has been tampered with. However, it’s a great hit with parents.


  • Available in all Blackberry, Android, Samsung smartphones, Nokia Symbian, and jailbroken iPhones.
  • The no-jailbreak version is available in iOS 9.0+. You’ll need the target’s iCloud credentials as well.

However, to use features like Keylogging to monitor Facebook, you need the jailbreak version.

Developer: Unknown


Part 7: Highster Mobile - Editor's Choice

Highster Mobile is a great Facebook Messenger monitoring app for several different people:

  • For people who don’t have too much money to spend on the app. It is the cheapest option in this whole list.
  • For people who don’t want to keep renewing the license, Highster Mobile offers a lifetime license with all features.
  • For people who don’t want to Jailbreak an iPhone, Highster Mobile offers a no-jailbreak alternative.

Highster Mobile logs conversations and data from all the popular social media and instant messaging apps, such as Twitter, Instagram, Skype, and yes, Facebook Messenger. You can then access your control panel and go through all the messages the target individual has sent/ received from others.

However, you should know that if you want to use Highster Mobile on an Android phone, then the Android phone needs to be rooted. There’s no other alternative.

Most Attractive Features (Other than Facebook Messenger Monitoring)

  • No-Jailbreak: Highster Mobile is a great Facebook Messenger Spy App because it’s one of the very few spy apps that allows you to monitor Facebook Messenger and other instant messaging app activities without having to jailbreak the iPhone. All you need instead is the target’s Apple ID and password.
  • Location Tracking: Highster Mobile is again one of the only apps in the market that allows you to track a person’s GPS coordinates without jailbreaking their phone.
  • Spy Camera: You can hijack the camera of the target phone and click pictures with it without the individual finding out. The pictures will then be sent to you discreetly and you can find out where the target individual is, or what he’s doing.

Why is this the Editor's Choice?

Because it's the cheapest app in the market that is not a scam. In addition to that, it's the only Facebook hacker that doesn't require jailbreak of an iPhone.

Part 9: SpyPhoneTap - Decent App with Poor UI

SpyPhoneTap is the bare-minimum spy app which can be used as a Facebook Messenger Monitoring App if, for some reason, all other apps are unavailable.

SpyPhoneTap doesn't have a specific feature to monitor Facebook messages, or any social media, however it does offer access to a control panel, and the ability to remote control the target phone, and as such you can access Facebook and view its activities.

It also has an extremely messy User Interface with a very erratic price package list.

Part 10: PhoneSheriff - Ideal for Parental Facebook Messenger Monitoring

PhoneSheriff is a really fun and interesting Facebook Monitoring App that is mostly meant for parents to use on kids, but you can use it for other purposes as well.

It has a strong and consolidated means of tracking and monitoring instant messaging apps such as WhatsApp, Snapchat, and Facebook Messenger. You can find out who the target is talking to, how long, and what about.

In addition to that, PhoneSheriff has a lot of blocking and filtering abilities. As such, if you don't want the target chatting with someone, you can block them from Facebook. You can also set up Profanity Alerts and Filters. With this you'll be notified every time the target individual uses one of those ‘keywords' you've set up.

Furthermore, every time the target phone will encounter such keywords, they'll be censored. This can protect your kid from exposure to sensitive content.

The "Show Icon and Notification" setting should be turned off because the default setting is for the icon to be visible and for the user to get notifications of being monitored.

  • Time Restrictions: Set up time period when the phone can go into lockdown.
  • Geo-Fencing: You can establish a perimeter so that whenever the target phone crosses it, you get notified.

Facebook Messenger Spy App Conclusion

So now you know about all the best Facebook Messenger Monitoring Apps in the market, and you also know about all the Facebook Messenger Spy Apps that you should ideally avoid. My personal recommendation is that you use one of the following apps - Neatspy, iKeymonitor, or FlexiSPY.

These three apps are very reliable and have their own pros and cons. Highster Mobile offers a no-jailbreak option for a cheap price tag.

Neatspy is extremely reliable and can perform Keylogging in addition to regular monitoring. FlexiSPY is extremely powerful and can directly decrypt password of the Facebook account using Password Cracker, however, it's very expensive.

Whatever you decide to use, please do leave a comment down below letting me know about your journey. I'd love to hear from you!
