In this section, I’m going to give an overview of the best spy apps and highlight their best features for spying on someone’s cell phone without them knowing.

A necessary disclaimer: only use these apps if you’re planning to spy on your minor children or on your consenting employees. Also, make sure to check your local laws before using such apps.

mSpy: Best Overall

Mspy homepage

mSpy is one of the most popular parental control apps around. Coming in as a complete package, it features monitoring, tracking, and even device management tools that can be controlled remotely. It’s also completely invisible, which makes monitoring easier.

With mSpy’s varied monitoring features, you can see essential information like call logs, messages, contact lists, browsing history, bookmarks, calendars, and more. You can even monitor all keystrokes with the keylogger.

You can also track your children’s actions on a wide variety of popular social media and instant messaging apps, such as Facebook Messenger, Instagram, Snapchat, and even on dating apps, like Tinder.

You can also track the target device’s location with mSpy’s comprehensive GPS tracking feature. With this on, you can track where your child is as long as their phone is connected to the internet. You can even set up a geofence around a zone and then be alerted whenever the target phone leaves the area.

Mspy dashboard

One of this app’s best features is its remote phone management feature. With it, you can control certain aspects of the target device straight from your mSpy dashboard, such as app blocking, contact number blocking, and website blocking. You can also lock the phone and wipe it remotely.

mSpy is compatible with mobile devices, such as on an iOS or Android phone. Their plans start at $48.99 for the 1-month plan, $83.97 for the 3-month plan, and $139.92 for the 12-month plan.

mSpy’s Best Spying Features

  • Remote phone control. With mSpy, you can better manage your kid’s digital life by controlling aspects of their device from a distance. You can block certain apps, block phone numbers from texting or calling, block browser access to certain websites, or even lock or wipe the device. All this from the comfort of your mSpy dashboard.
  • Comprehensive monitoring. With mSpy, you’ll always know what’s up with your children without them knowing. mSpy can show it all: contact information, SMS messages, call logs, and event calendar. It can also show all apps on the phone, browser history, bookmarks, and even monitor about 11 of the most-used instant messaging or social media apps including WhatsApp. Plus, it can also record every keystroke entered.
  • Reliable alert notifications. You have the option to be alerted every time the app recognizes a red-listed keyword or website. You can also track locations and set geofencing rules so that you can track the target device in real life. This feature assures you that you’ll be instantly updated whenever a potential danger presents itself.
  • Invisibility. Invisibility is an absolute must for people who want to spy on someone’s phone without the other person knowing. Luckily, you have the option to hide mSpy upon installation. If you go to your Apps list in the Settings, you can still see it, but it will be hidden under a different name, like “System Update” or “Update Service.”

Qustodio: Best For Screen Monitoring

Qustodio homepage

Another popular name in the spy apps industry, Qustodio is popular for its versatility and compatibility. It runs on mobile and desktop operating systems, such as iOS, Android, macOS, and Windows, and offers a wide variety of features that center around phone management.

You can spy on someone’s phone using Qustodio through its robust monitoring features. It can track call logs and SMS messages, installed applications, browser data, such as bookmarks and history, and some social media (Facebook and YouTube only). 

Qustodio social monitoring tab

This app also offers real-time location tracking with the target device’s GPS. You can pinpoint wherever they are on the map at any time and even set geofencing around specific locations.

Qustodio’s primary offering, however, is its robust set of phone usage management tools. With this parental control app, you have complete control over restrictions and time limits. You’ll know whether or not your children are keeping up with their online classes or simply procrastinating on the web.

For example, you can select which apps are allowed and which are not. You can also set automatic time limits for each app to force your children to stop using them for the time being.

You can also set time limits on the entire phone, which means that you can lock the device at specific times of the day or on specific days of the week. This makes it easier for you to completely control the target device owner’s digital exposure.

If you’re ready to purchase it, there are three annual payment plans: Small ($54.95 for 5 devices), Medium ($96.95 for 10 devices), and Large ($137.95) for 15 devices.

Qustodio’s Best Spying Features

  • Screentime limits: Qustodio lets you limit the screentime on the target device. Once it reaches the limit, either the device will be locked completely or certain apps will become inaccessible. Of course, you will be notified whenever the target device has reached the usage limit for the day, and the owner won’t even know.
  • Remote app control. You can use Qustodio to manage the apps present on the target device from your Qustodio dashboard. This feature lets parents fine-tune the restrictions for their children without having to go through the hassle of physically getting their kids’ phones.
  • Invisibility: Like mSpy, Qustodio also gives the option to hide the app icon upon installation. The app will then become invisible from the home screen and system tray so that the owner won’t notice that their device is being tracked and controlled.

uMobix: Second-Best Overall

Umobix homepage

Although not as well-known as the big names in the spy app industry, uMobix has a lot of useful tools to help you keep your loved ones safe.

uMobix is equipped with an SMS and call monitoring feature that lets you see records of how your kid behaves in calls and text. With this feature, you can see exactly what they’re talking about with their friends, and you can keep them away from associating with potentially harmful people.

Umobix calls monitoring tab

uMobix can also monitor most social media accounts, so you can keep an eye on what they do on their socials. It also has GPS tracking, keylogging, and more.

One of this parental control app’s stand-out features is its convenient installation process. Parents who don’t want to fiddle with too many options on the target device will love uMobix’s auto-permissions function, which cuts the things you need to do by about half. 

The iPhone version of the software even allows you to monitor the target device using only the owner’s iCloud credentials and without installing software.

Also, unlike other apps, such as mSpy, some really useful features work even without rooting or jailbreaking the device, including monitoring SMS, call logs, and email.

uMobix is priced differently for Android and iOS. For Android, the Basic package is $29.99 for a 1-month plan. You can upgrade to the Full package by subscribing to a 1-month plan ($49.99), a 3-month plan ($79.99), or a 12-month plan ($149.99).

iOS costs the same price for the Basic package, but the Full package costs $59.99 for the 1-month plan, $99.99 for the 3-month plan, and $179.88 for the 12-month plan.

uMobix’s Best Spying Features

  • Customizable sync frequency. Unlike other spy apps in the market, uMobix allows you to customize the time interval between updates. The standard time is 10 minutes every sync, but you can bring it down to 5 minutes to spy on someone’s phone closer to real-time. However, keep in mind that the shorter the time interval, the more strain there will be on the target device’s battery.
  • Social media monitoring. uMobix can monitor a long list of social media and instant messaging apps, letting parents become aware of most of their children’s online activities. However, there are differences in the available monitoring features between rooted and unrooted devices, so keep that in mind.
  • Spyware Scanner. As the name implies, this feature scans the target device to look for other spyware. It’s very handy because you should be the only one to have access to your children’s data. Otherwise, other people can also spy on their phones without them knowing and potentially expose them to danger.

Hoverwatch: Best For Businesses

Flexispy homepage

Hoverwatch offers solid tools and features to help you keep an eye on the target device of your child or employee. Compared to other bigger brands on this list, Hoverwatch is still rather new in the monitoring and spying industry. However, if you want to spy on someone’s phone without them knowing, this app is certainly nothing to scoff at.

It works smoothly in the background, without alerting the target device that it’s collecting necessary information like SMS messages, call history, and other basic information. The best part is that there’s no noticeable heat or battery drain on the device with Hoverwatch installed, unlike other spy apps on the market.

Hoverwatch device monitoring settings page

With Hoverwatch, you can control several settings on the target device from the comfort of your laptop or PC. This lets you access around 20 Hoverwatch functions and implement them without having to get close to the target device again.

Hoverwatch offers three price tiers based on the number of devices, with three different subscription plans.

The Personal plan covers one device and has three price plans: $24.95 for one month, $59.95 for three months, and $99.95 for a year. The Professional plan covers five devices:  $49.95 for one month, $99.95 for three months, and $199.95 for a year.

Hoverwatch’s Best Spying Features

  • Extensive remote settings control. With Hoverwatch, you can turn on or off 20 different functions without having to access the target device. This makes it incredibly convenient and safe to use.
  • No-root features. Spy apps often require root access to work properly. Although some Hoverwatch features need rooting, some important features (such as SMS, call logs, phone status monitoring, screenshots, and unlock selfies) worked during my trial even without rooting.
  • Unlock selfies and screenshot functions. These are two image-based features unique to Hoverwatch that lets you set scheduled screenshots to see what the target device is up to or to take a silent selfie every time someone attempts to open it.

FlexiSPY can monitor the standard information: SMS, calls, contacts, social media and IM, location, and apps. However, it ups the game by adding a real-time recording function to calls, FaceTime, video chats, and even ambient sounds.

Flexspy ambient recording feature

You can also remotely command the phone to handle the app itself, including deactivating, uninstalling, upgrading, or modifying it. You can even restart the device whenever you want with a built-in command.

Spyrix Keylogger: Best For PC Users

Spyrix Free Keylogger website homepage

It offers a nice set of features that you can use to monitor the activity being done on a computer. 

You can use your Spyrix account to remotely monitor the target device from anywhere. You don’t need to install the software or an app on your phone to view your account, simply log into your web account to view the data you’ve collected. 

In addition to this, you don’t need physical access to the target computer to uninstall Spywrix. You can remotely uninstall it from the target device through your web account. 

In regard to the target computer, the Spyrix Keylogger gives you access to a lot of data. The keylogger records all the keystrokes that are made on the PC. There’s also a Clipboard Control feature that records all of the content that’s copied to the computer’s clipboard. 

Spyrix web application dashboard

The target computer’s screen is also being recorded at all times, so Spyrix will take screenshots without the user knowing. This can give you insight into what they’re doing on the computer. 

Besides capturing the data from the screen and keystrokes. Spyrix also provides you with information about all the apps running on the computer, including games and iTunes. You can also view who uses the device and at what time along with information about removable drives such as USB, Hard Disk Drives (HDD), and Solid State Drives (SSD).

Lastly, Spyrix also grants you control of the printers connected to the desktop. There’s even an Analytics Module that allows for reports about the target device activity.

Family Link: Best Free Solution

Family link website home page

Giving children unrestricted and unsupervised access to the internet is never a good idea. However, phone monitoring apps can be costly and not fit a budget for the everyday parent. Luckily, there are free options to help you monitor your child’s internet usage. One of those options is Google Family Link

Family Link is a parental control app that you can create for your child with both of your Google accounts. It offers a variety of features that allow you to monitor your child’s digital activity and help them form healthy digital habits. 

You can set screen time limits for your child. This means that they can only use their devices for a preset time of the day. You can adjust it based on the days, less time on the weekdays and more on the weekends or holidays. 

Family Link also gives you the ability to block or allow apps. This will enable you to curate the content that your child engages with. You can even monitor their Youtube activity or direct them exclusively to YouTube Kids

Monitoring phone activity

Permissions Management is another way for you to monitor the content your child consumes online. You can view and manage the permissions for the websites and extensions that your child uses.  

In addition, you can secure your child’s Google account and data settings with Family Link. With it, you can edit their personal information, help them change their password, or delete their account. 

Lastly, the main thing for any parental monitoring app is location monitoring and Family Link takes advantage of Google’s GPS  tracking to help you keep aware of your child’s whereabouts. In addition to this, you can receive notifications about when your child has arrived at or left specific locations such as school or home. 

You can use Family Link on an Android phone running Android 5.0 and higher. For iOS devices, you can run Family Link on devices running iOS 11 and higher. Family Link is also available for Chromebook as well and works on devices with Chrome OS 71 and higher.

Download Family Link for free and help your child create better digital habits!

Family Link’s Best Features

  • Set screen time limits – with Family Link, you can help your child develop better screen time habits. This is done by creating time limits for how long your child can use their device or a specific app. When the time limit is up, the app or device is locked until the next day. This ensures that your child is not using their device for longer than they need to and will find other ways to occupy their time. 
  • Only allow age-appropriate content –  Family Link allows you to block or allow which apps your child can download. In the case of YouTube, it also allows you to monitor their YouTube activity and even allows you to choose whether they get access to the main YouTube app or the Kids’ version. 

In addition to controlling the apps they use, Family Link also allows you to block inappropriate websites and manage the permissions for them and their extensions.

  • Track their location – one of Google’s best apps is Google Maps, Family Link makes use of Google’s GPS location technology and allows you to track the target phone with Family Link active. This way you can know where your child is at all times. Family Link also gives you notifications when your child has arrived or left specific locations.

Which means they can’t spend the whole day watching YouTube videos. It also allows you to restrict new app downloads without your approval and blocks in-app purchases.

What To Look For When Choosing The Best Phone Monitoring App

Choosing a phone monitoring app can be a hassle. I’ll outline what to look for when selecting a phone spy app so you can easily make a pick.  

Pricing Plans

Check the pricing plans of a phone monitoring app before you sign up. For paid spy apps, Qustodio’s small, medium, and large plans seem more affordable than others. For free spy apps, Family Link is completely free to use


You can’t do much with a spy app if it is not compatible with your child’s device. Qustodio caters to multiple operating systems, unlike other spy apps. Some spy apps require jailbreaking or rooting to access specific features, but you can access basic features on XNSPY —such as remote phone locking and location tracking—without jailbreaking or rooting.  

Dashboard & User Interface

Phone monitoring apps should collect and present data in an accessible manner. So, check the intuitiveness of the spy app before signing up. uMobix and mSpy both have user-friendly interfaces. 

Setup Process

Check how much time and resources are needed to install the spy app remotely or physically, and if it requires technical knowledge/external assistance to set up. I discovered that uMobix has a more convenient installation process compared to others on this list. 

Tracking Features

The number of tracking features on a spy app determines how much you can do with it. After review, I discovered that mSpy is the best overall in this aspect, as it has extensive tracking features, unlike other spy apps on this list.

Spy Apps Comparison

I have compiled this handy table highlighting an overview of the spy apps I tested and reviewed in this post:

I know that having a great phone monitoring app can come in really handy as a parent/guardian. It’s always good to know what your child is doing online and in most cases, it’s better to be safe than sorry. 

As you’ve seen from the list, there are numerous great options that can fit any budget. You can opt for a free monitoring app, such as Family Link or Spyrix Free Keylogger. You could even opt for the free version of Screen Time or if you want more features the paid version. 

Other paid apps, such as mSpy, and Qustodio, are also great choices. They’re all great if you want to track your child’s location, and social media activity or manage their screen time.
