SPY24 is the best cell phone spy app for Android phones and iPhones.

SPY24 - Best Phone Spy App Overall
SPY24 – Best Phone Spy App Overall

This cell phone monitoring app has the most features in the industry, simple installation, live customer support, and the best refund policy. Let’s see why SPY24 is the best spying app for both Android and iOS mobile devices.
Best iPhone Spy App

SPY24 is the best iPhone spy app as it provides you with the most features without jailbreaking the device. It allows you to monitor more social media activities than any other app.

The following features set the SPY24 iPhone spying app apart from the competition:

Facebook Messenger View and files View

addition to all these features SPY24 is available on the iOS operating system. Compatible with any version. You do not need to jailbreak the device for installation.

Like all the best iPhone spying apps, SPY24 does not require access to the target iPhone to start monitoring. All you need is the iCloud login details of the user.

In fact, SPY24 will work on any iOS device (iPhone or iPad). Once you make your purchase you will be able to access all these real-time features in less than 5 minutes.

BEST PRICE Best Android Spy App The Android Spy App

SPY24Gyan is the best because it allows you to monitor more social media apps than any other spy app. This includes Facebook, FB Messenger, Instagram, Snapchat, Line, Viber, Tinder, TikTok, Kik, WeChat, Skype, Signal, Telegram, Reddit, and more.

All the best Android spy apps require that you have physical access to the target cell phone. SPY24 is no exception. The SPY24 app for Android phones is completely hidden and cannot be detected by the user of the phone.

Most Android mobile spyware apps require you to use the keylogger feature to monitor social media activity. But it only allows you to see one side of the conversation.

While it has the best Android keylogger without rooting, SPY24 basically offers social media monitoring, so you can view both incoming and outgoing messages. For apps that can’t be monitored, you’ll still see every keystroke.

This powerful Android spy app works with more mobile devices than any other phone tracker app in the industry. It works with all versions of the Android operating system. It even works with Google’s Pixel, which has the toughest protection of any Android cell phone.

There is no other Android tracking app in the market that comes close to the performance of SPY24.

LOWEST PRICE SPY24 is the best spying app on the market because it offers the most spying features, simple installation on any Android phone or iOS device, and the best and only lives phone support in the industry.

Check out my full SPY24 review for more details.

is the most reliable and feature-rich cell phone tracking app I tested. It is compatible with any Android device or iOS device.

Basic plan = $29.99 per month

Full plan = $14.99/month for 12 months, $33.33/month for 3 months, or $59.99/month for 1 month

SPY24 is the best cell phone monitoring application. It offers more features than any other iPhone or Android monitoring app in the market. It allows you to monitor everything the target person does on an iPhone or Android phone.

While they offer several subscription plans, the annual “full” package is the best value. And their refund policy is one of the easiest and most transparent in the industry.

It works on almost any mobile phone device including Android devices and iOS devices. To date, this is the most reliable cell phone monitoring app I’ve tested.

2. mobilet racker free

mobile tracker free is my second favorite spy software. mobiletrackerfree differs from SPY24 in a few important ways. Their app will not monitor multiple social media platforms and they do not offer live phone support.

If you need text message monitoring, GPS tracker, web browser history, phone call logs, and contact lists, mobile tracker free has you covered.

It also has some advanced features that you won’t find in any other phone spy app other than SPY24.

Mobile Tracker - Cell Phone Tracker Free - Cell Tracker
Mobile Tracker – Cell Phone Tracker Free – Cell Tracker

Why mobile tracker free Is No Longer #1

While mobile tracker free gives you access to Facebook, Instagram, Snapchat, and more, without rooting the phone, it doesn’t provide access to as many apps as SPY24.

They also do not offer live phone or chat support. If you have any problems during installation you will have to submit an email and wait.

This can be incredibly inconvenient if you don’t have regular access to the phone you want to monitor.

It is much less expensive than apps that offer similar features. mSpy (my #3 pick) requires the more expensive “Family Plan” to unlock these powerful features.

What you need to know before you buy

All the best mobile phone spying apps require physical access to monitor your Android phone.

mobile tracker free is no exception. But you don’t need to root the phone to get access to advanced spying capabilities.

Most smartphone spy apps use a keylogger to capture social media chat messages, but it only lets you see half the conversation.

mobiletrackerfree’s Android spy app includes this feature, but it also allows you to seamlessly monitor many of these apps, so you can see both sides of the conversation. In fact, no other mobile spy app I’ve tested gives you access to Snapchat without rooting the phone.

why is it important?

Not rooting the device means:

simpler app installation that doesn’t void the phone’s warranty
and more stable operation, so if the device is rebooted, the app won’t have to be preinstalled you’ll have
and less time Requires physical access to the phone

. The fixture is one of the best in the mobiletrackerfree group. I didn’t have any crashes during testing and there were no gaps in the data. Some Android spy apps will stop working after the target phone reboots or does a software update. mobiletrackerfree had no such problems.

Most importantly, they offer strong customer service and a transparent, hassle-free refund policy.

Satchel logs and name phone number of
simple user interface
camera remote control

Setkniki assistance through the email only

of my biggest frustrations with cell phone spying apps is that they are often unstable. But mobiletrackerfree was stable through reboots and software updates.

Trust me, the last thing you need to do when trying to discreetly monitor someone’s phone is to reinstall or troubleshoot software.

Overall Spike is my #2 spyware solution. This powerful mobile spy phone app allows you to see just about everything happening on the target device (Android and iOS). This is a great option for supervising employees, your kids or anyone.

mobiletrackerfree is a good alternative to iPhone or Android monitoring software. It is priced competitively, is stable, and has a no-nonsense return policy.

3. mSpy – Best Parental Monitoring Application

mSpy is the best parental monitoring application in this comparison. This is the only app that provides the ability to monitor screen time. if you need to monitor your kids

mSpy has been in the cell phone spy software business for a long time. It’s the most popular spyware in the world, but mSpy doesn’t offer the features of my #1 pick.

Until recently mSpy lacked many of the advanced features of its competitors. But their new Screenlogger feature (requires the family package), puts mSpy once again firmly in the top couple spots for Android devices.

This feature is only available with their “Family Kit”. It is not available in the premium version.

Many of the best spy apps for Android mobile devices require you to root the phone to view chats from Facebook, Instagram, and Snapchat. This is now built-in to the mSpy app.

Most apps require the installation of keystroke logging software that only lets you see what’s typed on the target phone. mSpy allows you to view the instant messages you receive in these chat apps.
Parental Monitoring App Features

mSpy’s Android spy software offers many of the usual features like GPS tracking, phone logs, contact list, multimedia files, and much more.

But they also offer phone screen recording and screen time limits so you can closely monitor your child’s phone usage. Most Android spyware in this category won’t allow you to limit your kids’ screen time.

They also provide very responsive technical support. This may not seem like a big deal, but if you are not tech-savvy, it can be a lifesaver.

For more detailed information, including a look at the user interface, you can read more in my mSpy review.

Require Jailbreak Their basic monitoring solutions do not require jailbreaking and are great for those. Those struggling with technology.

It offers the ability to monitor WhatsApp, but not any other social media accounts. The full version of mSpy gives you much more features including monitoring the location of the target person. It’s not even detectable once installed.

mSpy is my #3 choice.

Although it doesn’t offer many social media monitoring options, it is still a solid option. You will be able to see all texts, iMessage, and WhatsApp messages.

It doesn’t offer some of FlexiSPY’s advanced tools (like call interception or call recording), but this cell phone spyware app still offers good value overall. And FlexiSPY (my #5 pick) needs to be rooted for these advanced features.

4 . Cocospy

Cocospy is a relatively new addition to my list of monitoring solutions. They provide a similar feature set to mobiletrackerfree.

This is a great app for monitoring a child, loved ones, or anyone else. Their features include everything you would find with mobiletrackerfree.

The web control panel has an easy-to-use menu that allows you to quickly view all of the phone’s information.

The app is hidden and undetectable
Powerful keylogging feature
simple user interface
Easy installation, no root or jailbreak required.
Log Phone Calls, GPS Location History, Call Data


From SPY24 reduce social media access
Technical support via email only
Does not offer more advanced capabilities like live call listening

One of my biggest frustrations with spyware is that apps are often unstable. Cocospy was stable through reboots and software updates.

Trust me, the last thing you need to do when trying to secretly monitor someone’s phone is to reinstall or troubleshoot software.
price ceiling

Basic plan = $29.99 per month

Full Plan = $14.99 per month for 12 months, $33.33 per month for 3 months, or $59.99 per month for 1 month

Cocospy is a solid app that offers the same features as mobiletrackerfree. This is great for supervising kids, employees, or loved ones.

Of 5. FlexiSPY – Powerful Spying App With Call Recording

FlexiSPY Extreme Software is the most powerful spying application on the market. While they don’t offer a specific business plan, it is the best solution for business owners because you can order a phone with the software already installed. This makes monitoring of employees very easy.

It has all the real-time call monitoring features of the other products I’ve listed, plus some incredibly powerful advanced features that aren’t offered by any other mobile phone monitoring app.

FlexiSPY has a call recording feature so that you can record phone calls. You can also listen to the phone call live in real-time. No other app provides this functionality.

You can also spoof SMS messages, or send them on behalf of the phone owner.

On top of that, the app itself is very stable, and its support is responsive and efficient.

FlexiSPY differs from SPY24 in two important ways. They do not offer live phone support. And FlexiSPY requires you to root the target device to get the most powerful features.

Most Powerful Mobile Spy App Available
Advanced Features: Listen Live Calls, Call Recording Facility, View Call Log
Stealth mode means it’s hidden and invisible
is listening to the surroundings of the device, the remote control of the camera
control apps
SIM card change notification, SMS command
Log phone call record, text message, location, call data


iOS installation requires jailbreak
Requires routing for full functionality
Has a higher cost than other options

Where this product really shines is when you order a device with FlexiSPY preinstalled on the target phone. It gives you full access from day one!

FlexiSPY sets the bar for other spying applications by offering the most advanced features. Most notably it allows you to do call recording, listen to calls live, make FaceTime calls and listen to the surroundings at any time.

Lite Key = $29.95/month for 1 month

Premium = $12/month for 12 months, $33/month for 3 months, or $68/month for 1 month

Extreme = $29.08/month for 12 months or $66.66/month for 3 months

If you’re comfortable with technology and are willing to spend a little more, FlexisPY is the most powerful spying app on the market.

Although it has a high price tag, the Flexispy Extreme package has unmatched spying capabilities, allowing you to record calls and listen to live calls.

Where FlexiSPY really shines is in its advanced features. You can read about it in my full FlexiSPY review.

6 K. iKeyMonitor – Cheapest Spy App

iKeyMonitor is one of the most affordable options available. It is an easy and user-friendly spying app that has many of the cell phone spying features of other apps we have covered. It also includes an online dashboard to view data on targeted devices.

You will need to root or jailbreak the device to get the full services of iKeyMonitor. So if you are uncomfortable with that process, you should go with one of my first two options. The keylogging feature is quite powerful but requires rooting or jailbreaking the target device.

Basic But Powerful Spy App
Free Trial 3 Days
Monitor Internet Connection, WhatsApp Messages, and More
Monitor Chat Apps
capture screenshot
screen-time limited
data usage


Powerful features require jailbreak or rooting
Has higher cost than other options

Key iKeyMonitor is another solid smartphone monitoring app. However, it requires you to root or jailbreak (iOS) the device for maximum access. The bottom line, it offers many of the same great features as the others, but at a more reasonable price.
price ceiling

iKeyMonitor Full – $59.99/or

Month$29.16/month for 12 months

The iKeyMonitor package is pretty solid. Setting up the app was a little more technically involved than other apps we tested, but it seemed pretty stable. All spy functionality works as advertised, and the app is hidden from the end-user, making it completely undetectable.

You’ll pay an extra $6 per month compared to our first choice, and get basically the same functionality, so it came in at No. 5 in our comparison.

7. spirea

Spira is another great remedy.

Spyra has many of the same features as other monitoring apps. Because Spyera is easy to use, install and configure, it is a good option for those who are not technically savvy.

nice feature set
Works with Android or iOS

mediocre support
Lacks some of the more advanced spying features

The interface and online dashboard capabilities are similar to other cell phone monitoring software we’re covering, but they lack some of the advanced capabilities in this app. You can read about this app in my Spyra article.
price ceiling

$6 purchase

Outright Spira of 9.99 is one of the better budget spy phone apps on the market. This spy software lacks some of the more advanced capabilities.

Spyera offers a one-time annual payment. Yes, it doesn’t have some features like call recording, ambient recording, and turning on the camera, but it is still a robust package for spying on one’s online activities.

XNSPY is one of the more innovative spy apps on the market.

It shows you call logs, allows social media account monitoring of apps (Instagram, Twitter, WhatsApp), photos and videos, location tracking features, and has some impressive extras.

XNSPY – Basic Version: $29.99/or $59.99/year

MonthXNSPY Premium Version: $35.99/month or $89.99/year

Live Control Panel is a nice add-on, but where it really excels is when you need to monitor multiple devices.

XNSPY’s free customer support is not that great. But you can find the answer to any question on their website.

9. Highster Mobile – Avoid!!!

Hyster Mobile is a complete waste of time and money and should be avoided at all costs. They lack advanced espionage facilities, their technical support is non-existent and their refund policies are shadowy Air Force.

I was first attracted to Hyster because they offer a one-time payment option. It sounds great, but I wasn’t able to get the product to work. And, of course, no one responded to my request for a refund.

You get what you pay for and Highster is not worth it.
Why Use Spyware Apps?

There are three main reasons to use spyware apps.

A parental monitoring application to view your children’s social media presence
Cell Phone Monitoring Solution for Employers to Track Employees
in relationships who want to spy on their partner’s cell phone and computer activity

The first two are legal. The third is only valid if you obtain the consent of the person being monitored.

Mobile Phone Spy App FAQ Mobile Spy App

Here are answers to common questions people have about installing and using them.
Do Cell Phone Spy Apps Really Work?

Phone spy apps work really well. They are a powerful way to carefully monitor someone else’s smartphone. Some apps don’t even require physical access to the target device.
How do phone spy apps work?

Phone spying apps work by saving data from the target device and storing it on a server to be viewed.

iPhone spy apps work by logging into the user’s iCloud account. Phone (or any iOS device) data is stored here and is unencrypted. This allows the iPhone spy software to access most of the mobile phone’s data.

Some spy apps for iPhone can be installed locally on the device, but it requires jailbreaking first.

Unlike the iPhone, Android cell phones do not have a cloud backup option. An Android phone spy app must be installed on the Android device itself.

This requires physical access to the phone and knowing a passcode to unlock the device. Once installed the app sends activity data to the server for viewing.

Can spy apps be installed remotely?

It is not possible to remotely install spy apps on Android mobile devices. You must have physical access to the target Android devices.
Even though the iPhone has incredibly powerful encryption, spyware can be installed remotely on the target phone because all data is accessed through the user’s iCloud account.

Is it necessary to root or jailbreak the phone?

Some spyware apps require you to root the phone to get the most advanced spying features. None of my top 5 picks require the target phone to be rooted or jailbroken.
FlexiSPY, the most powerful iPhone spying app, is an exception.
However, Android spy apps require you to install the app directly on the device. You must have physical access to the phone for this.

Is my phone being monitored?

If you see suspicious-looking apps on your smartphone then someone may be monitoring you.
The way to check for spyware is different for both iPhone (iOS) and Android. The easiest way to check for spyware is to install powerful antivirus software. This article shows you how to check for spyware on an Android phone.

What is the best free undetectable phone spy app?

iKeymonitor is one of the only free hidden spy apps out there. They offer a free Android spy app. Unfortunately, the free version only offers few features as compared to the paid version.
In general, free spy apps are not worth the time it takes to install them. Since they don’t make money there is little motivation to keep them updated.

Which is the cheapest spy app?

The cheapest spy app is SPY24. A 12-month subscription to an iPhone costs $12.49 per month. A 12-month Android subscription costs $14.99 per month.
Spy apps are the best way to monitor someone’s social media activity. These apps allow you to do all of the following:
monitor someone’s Facebook messenger
spy on Snapchat messages of tinder messages
spy Instagram
tik tok

parental controls

Phone spying apps are different from parental control apps. The most parental control software has features such as screen time monitoring.
