If you need to spy on someone’s iPhone, you’ve come to the right place.

In this post I’ll reveal the 6 best iPhone spy apps.

In fact, these 6 are the ONLY iPhone spy apps out there that are worth your money.

Trying to pick the right app can be confusing as hell. There’s a lot of inaccurate information out there.

Take it from someone who lost over $100 on their first choice and never got it to work.

Eventually I found a handful of apps that offer all the features you could ever need, reasonable pricing, helpful tech support and legit refund policies.

In this comparison you’ll learn:

  • The ONE THING you absolutely must know about iPhone spy apps.
  • Which apps to avoid so you don’t get ripped off by sneaky refund policies that cost me $100 and several hours of my life.
  • The must-have features you absolutely need for peace of mind and getting the answers you need.

I don’t care whose phone you want to monitor or why, no one deserves to get ripped off.

Many of the apps on the market claim to offer similar features, but what they don’t always offer is reliable performance.

And God forbid you need tech support. Cause all you’ll hear is crickets.

So here’s my list of the best spy apps for iPhone.

Best Spy Apps for iPhone

Since many spy apps for iPhone offer similar features, what separates the good from the bad is their stability, functionality, and customer support.

An app is only helpful if it works consistently and is easy to use.

If you’re having trouble getting your app to work and have no support, then your app is essentially useless.

Another difficulty when choosing a spy app is that they often require rooting to be most effective. The rooting process can be pretty intimidating if you’re not an expert with iPhone and iOS devices, and can be expensive if you try to hire someone to do it for you. 

It also requires physical access to the cell phone.

To make the decision process easier, I’ve compiled a list of 6 top iPhone hidden spy apps based on the features that can be used without rooting the cell phone.

I’ve also included some pros and cons, pricing information, and device compatibility to help you pick the best spy iPhone spy app for your needs.

Best Hidden Spy Apps for iPhone

1. mSpy – Best Overall

mSpy logo

mSpy is my number one pick of all the spy apps for iPhone. It offers the most versatility and functionality without having to jailbreak the cell phone.

mSpy is especially useful when it comes to viewing texts, as the app will send a copy of all messages your child sends or receives to your parental dashboard where you can view them whenever you want, regardless of if your kid deletes the originals.

mSpy will even let you view photos or videos your children send or receives through text messages.

Unfortunately you can’t monitor social media apps or email without rooting the device.

You can control which WiFi networks your kids can access and which websites they can visit. You can also see internet history and set up an alert in case keywords are searched or used on your kid’s phone that you’re not OK with.

mSpy uses a powerful keylogger feature that replaces the keyboard in your kid’s phone with one that can track everything they type on it. This can help you monitor your kid’s activity even on the social media apps that you can’t access directly.

This means that you can record anything your child types and can receive an alert anytime your child uses a keyword or phrase that you’ve chosen, no matter what platform they are using.

You can also prevent your child from downloading specific apps and view what apps are already downloaded on their phone. You can also block incoming phone calls and see their call history.

All of this is sent to a parental dashboard that you can view on your phone whenever you want. And of course the mSpy app icon remains completely hidden.


  • One of the best tech support teams
  • Monitor social media: Instagram, Facebook, Snapchat, Whatsapp
  • App is stable and doesn’t crash often
  • Best keylogger that makes up for lack of social media messages
  • No need to root for tracking
  • View photos, browser history, camera, contacts, & more
  • Works with a wide range of devices
  • Great for parents


  • Can be expensive
  • Can’t view numbers unless they are saved as a contact
  • Rooting required for gps tracking
  • Rooting required for social media activities


Premium = $16.66 per month for 12 months or $39.99 a month for 3 months or $69.99 a month for 1 month

Basic = $29.99 per month for 1 month


mSpy can also be used on any version of the iOS software.

In addition to being rated the best spy app for iPhones, mSpy was rated one of our best spy apps overall. For more information on this software check out our full review here.

#2. FlexiSPY – Most Powerful

flexiSPY logo

FlexiSpy is another spy app that has a pretty impressive set of features that don’t require rooting to use.

All the standards you would expect to see are covered including text message monitoring through a keylogger software, access to call logs, address books, and installed applications, the ability to view photos and videos sent to the target smartphone, and application and network blocking.

Notably, Flexispy doesn’t allow you to access internet browsing history or bookmarks online without first rooting the target device – a feature that most apps do include in their non-rooting option.

You also can’t directly monitor most social media – though you can read WhatsApp messages – but the keylogger can make up for this by recording anything typed into the phone’s keyboard.

FlexiSpy does offer some impressive features that you may not find with other iPhone spy software. This includes features like geo-fencing and viewing of GPS location.

Where FlexiSPY truly shines is in the capability of the “Extreme” plan. This allows you to listen to calls live and record them. It also gives you access to pretty much everything on the phone.

Flexispy can send you an alert when your child has an incoming call, and can even choose to record that call and have the recording sent to your dashboard so you can listen to it later.

You can also remotely activate the microphone and record what is being said in the vicinity of the target device. You can also remotely change software that is downloaded onto the target phone or remotely deactivate software.

Another nice feature is that you can choose to run FlexiSpy in hidden mode, which means the app icon is hidden and there is no indication on the device the app is running in the background.

All these extra features are reflected in the higher price point, but the strong customer service and extra options can make this an appealing choice.


  • GPS location, Geo-Fencing
  • See social media accounts: Facebook, Snapchat, Instagram, Whatsapp
  • Ambient recording, call recording, remote control of camera
  • Access photos, browser history, camera, contacts, & more
  • Works with a wide range of devices
  • Strong customer support
  • Easy to use control panel


  • No internet monitoring or controls
  • No screen time control options
  • Some features aren’t effective if the target device has poor reception
  • Expensive
  • Requires physical access


Extreme Plan = $29.08 a month for 12 months or $66.66 a month for 3 months

Premium Plan = $12 a month for 12 months or $33 a month for 3 months or $68 a month for 1 month

Lite = $29.95 a month for 1 month


FlexiSPY works with all iOS versions but does require jailbreaking the phone first.

#3. Spyzie

This app has an impressive array of phone monitoring features, and all of them can be used on iPhones without the need for rooting.

You might be wondering why, then, this app isn’t further up on the list. The answer is due to the unreliability of the product, the frequent problems the software encounters, and the lack of customer support.

Spyzie provides the basic features like text message and call log reports, multimedia viewing, browser history reporting, app blocking and control, and GPS location reporting.

This app also offers email access, has a keylogger to track any information entered into the phone, and allows you to directly monitor popular social media platforms like WhatsApp, Facebook Messenger, Skype, Instagram, Tinder, Viber, Snapchat, and more.

You can also set geo-fencing parameters, establish certain alerts to be sent to your phone, and can even take screenshots of anything on your kid’s phone which can come in handy if you think a confrontation may be in order.

This app doesn’t let you record calls or give you any way to listen to conversations your kids may have either through calls or video chats. Still, the list of options they offer without needing to root your phone may be tempting, but you should be aware of the instability of this product.

There have been several reported instances of the app crashing after updates or reboots, to the point where the app may need to be uninstalled and reinstalled to work again, which can be inconvenient given the fact that this requires physical access to the mobile phone to install the app.

Also, like Highster, there is no live help option. You can contact customer support, but they say on their website that it can take up to 48 hours to get a response. Several customers have reported that it’s difficult to get a response at all.

Installation is straightforward and once your account is setup you ready to go.


  • Comprehensive set of features without rooting
  • Thorough app monitoring software
  • Remote control screenshot capabilities
  • Geo-fencing and GPS location tracking


  • Frequent stability issues
  • Poor functionality
  • Unreliable customer support
  • No call recording


Basic Plan:  1-Month License: $29.99 / 3-Month License: $49.99 / 6-Month License: $89.99

Pro Plan: 1-Month License: $39.99 / 3-Month License: $69.99 / 6-Month License: $99.99

Ultimate: 1-Month License: $49.99 / 3-Month License: $79.99 / 6-Month License: $119.99


Spyzie claims to be compatible with all iOS versions.

#4. iKeyMonitor – Simple & Effective

ikeymonitor logo

iKeyMonitor also has a nice range of features available without requiring you to root the phone. The basics you would hope to find in a spyware app are available, including text message monitoring, a keylogger to record anything typed into the phone, the ability to monitor photos and videos sent to and from the device, call history viewing, and the ability to view browsing history.

This app also provides some extra features that aren’t always included in spying apps, including call recording, location monitoring, geo-fencing, the ability to monitor and block apps, some social app monitoring, and even some tools to limit screen time.

They also offer the ability to take screenshots of email, internet activities, and app activity that takes place on the target device. You can also remotely trigger the microphone in order to listen to what is going on in the vicinity of the phone in question.

Unfortunately, it is one of the most expensive options on this list. They don’t offer plans for rooted vs. non-rooted phones, so if you don’t want to root the device, you still have to pay for the full package without being able to use all the features.

This app also doesn’t come with great customer service. There is a live chat option, which is better than some of the other apps available, but the tech support is known to be lacking and not very helpful when it comes to actually resolving problems. It also crashes frequently and requires access to the target device if it needs to be reinstalled.


  • Good range of features that don’t require rooting
  • Call recording
  • See photos, browser history, camera, contacts, & more
  • Geo-fencing and tracking
  • Screenshot capabilities


  • Expensive
  • No non-rooting plan option
  • Poor customer service and support
  • Unreliable functionality


Free Version: $0 + $9.99 every 3 days (approx. $100 a month) for most features

Full Version: $29.16 a month for 12 months or $59.99 a month for one month


iKeyMonitor can be used on any iOS device and does not require jailbreaking.

#5. Spyfone

SpyFone Logo

Spyfone is another parental control app that offers a comprehensive set of features for iPhone, and most are accessible without having to root the target device.

In fact, unlike most software, Spyfone doesn’t have separate rooted and non-rooted plans.

At the highest tier, Spyfone gives you access to features like website blocking, viewing photos, keylogging to track passwords and sms texts, location and GPS tracking, the option to block or control applications, and the ability to view all media on the target device including pictures and recorded video.

Spyfone also includes live viewing options that aren’t available through most other iPhone tracking apps. Live viewing allows you to tap into your kid’s iPhone devices and see what they are doing in real time.

This is especially helpful if you want to know immediately when they are engaging in potentially dangerous activity instead of waiting to check activity once it’s recorded and ready for review in a parental portal.

You can also turn on the camera on your kid’s phone remotely and see what they are doing and what is happening around them as it occurs.

Unfortunately, Spyfone doesn’t let you intercept or listen to calls live, but you can record calls and listen to them later.

As great as Spyfone is, it’s somewhat lacking when it comes to screen time and web filter controls. There is no good way to impose time limits with this app, and while there are some website filters, they aren’t as detailed and strong as they could be.

There is also no geo-fencing option, and while there is live gps tracking, it can sometimes take up to 15 minutes for location information to update from devices, which can make it pretty difficult to keep accurate tabs on your children.

Thankfully, Spyfone does have great customer service, with 24/7 chat support available to help you with any issues that may come up when trying to install this app on an iPhone. They can also install the app for you if that’s something you don’t want to mess with yourself!


  • One of the best support teams in the industry
  • GPS Tracking
  • Monitor social media: Whatsapp, Snapchat, Facebook, Instagram
  • Ability to view activity live in control panel
  • Remote camera control and view photots
  • No rooting required
  • Impressive keylogging allows to read instant messages
  • 24/7 customer support and installation assistance
  • Compatible with lots of devices


  • Location reporting can lag significantly
  • One of the more expensive options
  • No geo-fencing
  • No screen time controls


Xtream = $25 per month for 12 months

Premium = $16.66 per month for 12 months

Basic = $8.33 per month for 12 months


Spyfone can be used on any iPhone.

#6. Highster Mobile Spy – Avoid at All Costs

highster mobile logo

Highster offers some decent spy tools, but is somewhat limited when it comes to what you can do without jailbreaking your target device.

Even if you do jailbreak the target phone, Highster doesn’t offer as many advanced features as you could find on just about any other spy app.

They do offer text message monitoring, the ability to access media files, incoming and outgoing email monitoring, and the ability to view user calendars, notes and other data stored on the target device.

You can also view what calls are being made or received, though you can’t record these calls, listen in, or place any restrictions on incoming or outgoing calls. Y

ou can receive GPS location information, though, which is something that doesn’t come standard for a lot of non-rooted versions.

Unfortunately, you can’t monitor any popular social apps, and there is no keylogger feature included in the available features, so you have no way of knowing what messages may be passed along using anything that isn’t a text message or email.

You also can’t block websites or network access, though you can view user browsing history and bookmarks and can set up keyword alerts for search terms.

The area where Highster is the most lacking, though, is in the customer support department. There is no chat support or even a phone number you can call if you need help with your account.

You can submit a ticket with a help request through their website where they promise someone will get back to you within 24 hours. But that’s not much help if you have a problem that needs an immediate solution.

Highster does have an extremely low, one-time payment, though, so if you don’t want a lot of extra features and aren’t worried about the lack of support, this app could be the solution for you.


  • One time payment
  • Track location, call logs
  • View photos, browser history, camera, & more
  • See emails
  • Call monitoring
  • Monitor Whatsapp, Viber, Skype, Facebook, Snapchat, Instagram
  • Simple control panel


  • Terrible customer support
  • Limited features and devices
  • Often has trouble upgrading
  • Unreliable operation
  • No keylogger
  • Terrible refund policy


Basic Plan = $29.99, one-time payment

Pro Plan (requires rooting) = $69.99, one-time payment


Highster can be used on any iOS device.

How We Rate Spy Apps

These smartphone tracking apps have a variety of uses. You can the phone of your kids, employees, partner, whoever.

Our criteria for picking the top software boils down to the same things whether you use it to track kids, an employee, or whoever.

As an employer, concerned parent, or whoever, a solid and reliable product is key.


Price is an important factor since most parents have limited resources. A high-powered spy app might look appealing, but if you can’t afford it, then it’s not worth getting excited about!

One question we always get is regarding free spy tools. Free spy tools have their place, but they offer EXTREMELY limited data. In fact most of the free spy software is so limited that it is essentially worthless.

Ease of Use

One of the best ways to evaluate a spying app for iPhone is the ease of use. If you can’t figure out how to make your spyware work, or you have to spend many frustrating hours trying to figure out how to get certain features to work properly on the target cell phone, then your iPhone spy app also won’t do you much good.


The installation of the software needs to be relatively straightforward. Smartphone security is tough to beat, but one important feature is definitely ease of installation.


geo fencing from dashboard

Some parents are concerned with things like location tracking, photos, contacts, call logs, geo-fencing, and other data, while others might be more concerned with seeing what goes on in apps or knowing who is calling their kids.


This is another important factor, since a spy app that won’t function properly is also pretty close to useless. You don’t want to spend money on a product that won’t keep working reliably!


It’s important to know what the limitations are of anything you’re going to spend money on so you can make informed decisions. Make sure you’re going to get the data you want from the product you choose.


how you can spy on an iphone

Thankfully, the best iPhone spyware is usually compatible with most devices, but it’s still important to make sure the product you’re buying will work with your specific device.

Customer Support

Any software is bound to develop issues at some point. Having responsive, reliable, helpful customer service is important when trying to pick a good iPhone spy app.

Live Demo/Free Trial

This can help you get a feel for what an spy app for Android can do before you spend money on it. Not all the software reviewed here offer this option, but a quick visit to their websites will help you find a free trial or live demo if they’re available.

iPhone Spy App FAQ

What is Rooting?

Many spyware programs require rooting or unlocking the operating system of the monitored device to enable certain functionality. These features include social media chat apps. This is true of both Android and iOS operating systems.

Android spy apps typically require this be handled before the installation process begins.

Can you spy on someone’s iPhone without having access to it?

Yes, you can absolutely spy on someone’s iPhone without access to it, but you’ll need to know the users iCloud credentials.

While some spying apps can be installed remotely, some apps will require brief access to the target cell phone due to their advanced features.

Can someone read my text messages from their phone?

If there is a spy app installed on your phone, then chances are, someone will be able to read your text messages. Most spy apps provide people with text message monitoring in standard, non-rooting packages.

Is There a Spy App on My iPhone?

Most of these apps can run undetected, but there are a few ways to tell if someone has installed one of these apps on your device.

A fast-draining battery or a phone that feels like it overheats quickly are both signs that a spy app may be running in the background. Your mobile data draining faster than you think it should can also be a sign of a spy app.

You can also install some spy-detection apps that may be able to detect a hidden monitoring app.

How can I track someone’s location?

Most – but not all – of these apps offer location tracking features. If this is important to you, be sure to check if the app you’re considering offers this feature, and if the location information updates accurately.
