Using a spy app on someone’s phone to monitor his or her activity is not a new trend as those monitoring apps exist for a long time. What’s new is these apps, which were extremely rare and were considered a novelty, are now available in the market for regular users for an affordable price.

Best Hidden Spy Apps For Android

There are plenty of apps if you just search in Google for terms like best phone spy apps, etc. But to know which app is the best for your particular use case can be real pain unless you use each of the apps.

But that’s a pretty unrealistic solution, right? Nobody in their right mind can think of using most of the spy software available in the market just to find out which is the best, especially when most of them are not free.


And here we came to your rescue! As an independent security company, we have used and analyzed all the leading monitoring tools extensively and came up with a list; so that you don’t have to do the hard work.

Here we have enlisted only the top ones, so you can select any one, and you won’t be disappointed for sure. So, without further ado, let’s get started with today’s review of top spy apps for android.


One of the best apps we tested in our facility is FlexiSPY. You’ll get to do some amazing stuff with this software like you can remotely view and listen to the surrounding of the target device by activating both microphone and camera app, record every keystroke, monitor chat apps, and many more. 

Furthermore, it can operate in stealth mode so that no human eye, or the app drawer, or even antimalware apps could detect its existence.


It’s a premium app, so it will cost you dearly – but make no mistake, it worth every cent it charges. As it’s an app that belongs to the “spy tool” category, Google doesn’t allow it in their Play Store. So, you have to purchase and download this app from the official website.

We have used this app in literally every android phone, and it passed with flying colors and even exceeded our expectations in some cases. If you want to monitor a android Smartphone, specifically from the model S4 to S8, this software is an absolute no-brainer choice.


Another great contender in this list is Spyera. If you’re searching for a right spy software solution in Google, you sure have come across this app already. We used this app mostly in android phones, and it produced some unexpectedly fantastic results.

With this monitoring tool, you’ll be able to listen to the live phone calls, record phone calls to listen later, listen the live calls made through VoIP channels (like Skype, WhatsApp, Messenger, etc.), listen to device surrounding, track and monitor GPS position of the device, read emails and spy on text messages, view browsing history, log browser bookmarks, access photo gallery, and file manager, etc.


You’re also entitled to get lifetime free updates and upgrade for the software, as long as your subscription lasts. We found their pre and post-sale support is nothing but fantastic as they went some extra miles to help us install the app in the target device by providing step-by-step guidance in live chat.


This one is probably the easiest tool we tested as part of this review. You can install this software in any android phone without much hassle – only a few taps, and it will get installed.

It offers a vast array of features, and we tested each of them successfully. You can listen to every word of your kid talking on their phone, and you’ll know who they are talking to as well.

You can export the contact book and call log from the target device and save them in your personal account dashboard for future checking.

Want to check where your kids are right now? Want to know where your employees are at the very moment? You can check real-time location by tracking the device GPS with high accuracy.


Do you want to set a customized list of sensitive terms or keywords and want to be notified whenever kids are using those terms on their phone (in chat, email, browser, apps, etc.)?

Yes, that’s possible, too, and you can set 24×7 alert so that you receive the notifications instantly whenever your kid is using any of that specific keywords in his/her phone.

It has most other regular spy features like other apps, but one unique feature we must mention that you rarely find in any other app. That is rootless WhatsApp monitoring. Usually, you need to root your android device to spy on the chats – but XNSpy doesn’t need the device to be rooted.


This is the final spy app we want to mention here, and to be honest, we saved the best for the last! Wait, did I say it’s the best app? Yes, I did. And you’ll know why right now. So, fist, let’s start with the fantastic features this spy app comes with.


Vast compatibility

NEXSPY is the only app in this review that’s compatible with PC, Mac, iPhone, iPad, and of course, Android. No other app here offers such versatile usability, so this feature makes NEXSPY stand out in the crowd of spy apps.

Social media spying

No matter what social platform your kid or spouse prefers, you can spy their every activity. No other spy tool works on many social platforms like NEXSPY.

VoIP recording

With NEXSPY, not only regular calls – you can record VoIP calls in most of the popular VoIP providers.

NEXSPY dashboard

Application monitoring

You can monitor what apps your kids are installing in their phones with NEXSPY, and you can blacklist an app to be installed if you want. Like, suppose you don’t wish your 13-year-old girl use Tinder, you can make that app blacklisted from your Nexspy account – and then rest in peace as your kid will not be able to install that app in her phone.


This is another aspect of NEXSPY we must mention. While it’s not free software by any means, it’s surprisingly affordable than other spy apps compared to the features and functionalities. If you go for a yearly plan, it costs only $19 per month for each device, which is even lesser than the cheapest option in the market.
