In case you’re late to the party, spy apps are monitoring software that help you to track people’s devices to find out what they’re up to. They are well regarded for their ability to operate in stealth mode, making it difficult for victims to find out they’re being hacked.

Spy apps are available for Android and iPhones. However, not all apps can work on both devices. Also, there are many spy apps out there that simply don’t deliver as promised. To save you from a potentially horrible situation, we’ve compiled a list of 5 of the best iPhone and Android spy software on the market.

Top 5 Spy Apps for Android & iPhone

While there are many great apps to monitor people’s phones, the following are considered the best due to their performance, features, and user reviews.


mSpy is arguably the most popular spy app on this list. It comes with over 30 features and a reasonably affordable subscription fee. Some of the features include:

  • Text message tracking. Want to see someone’s incoming and outgoing texts? mSpy gives you full access to their sent, received, and even deleted messages with time and date stamps.
  • Call monitoring. This feature provides you with access to incoming and outgoing calls with timestamps, call duration, and chronology.
  • Social media monitoring. mSpy gives you no holds barred access to social media accounts. With this feature, you can monitor people’s Facebook Messenger, Instagram, Snapchat, WhatsApp, etc.
  • Keylogger. Keylogger records all pressed keystrokes on a target device. This could give you access to passwords, usernames, and everything else the victim types on their phone.
  • GPS Location. With mSpy, you can monitor the target’s GPS location and see where they are or the places they’ve been to.

To start monitoring with the mSpy hidden spy app, simply visit their website to choose the type of device you wish to spy on, subscribe, and download the app on the target phone.


SpyBubble is another popular phone monitoring app for Android and iPhone. It has over 25 features, including SMS and call monitoring, social media monitoring, tracking GPS location, and Geofencing.

Users will be able to monitor the victim’s incoming and outgoing calls, read text messages, and have access to 24/7 customer support. SpyBubble works on most iPhone versions without jailbreak. However, it requires the target’s device to be rooted if it’s an Android.

SpyBubble requires you to sign up with your email and target’s device information before paying for a subscription. When the registration is complete, you’ll receive an email containing a download link and how to install it.


Spyic is an excellent spy phone app for Android and iPhones. It comes with lots of features, including SMS and calls monitoring, social media monitoring, tracking browser history, GPS location tracking, and geofencing.

Like the other apps on this list, simply register for a free account to start using Spyic. Choose the device you wish to monitor and pay a subscription fee.

Spyic gives you a 60-day money-back guarantee in case you’re not happy with their services. But from all that’s been said about this app, we are quite sure there will be no need for refunds.


FlexiSpy is one of the best Android spy apps that also work on iPhones, PC, and Mac devices. With this app, you’ll be able to monitor social media apps, iMessage, GPS location, and installed apps.

FlexiSPY can record the target’s phone calls and hack the phone’s recorder to listen to sounds coming from the environment. You can also order a brand-new Android or iPhone device with FlexiSPY already installed. This eliminates the hassle of app installation.


Spyine doesn’t require rooting or jailbreaking and is compatible with iPhone, Android, and tablets. It comes with over 20 features, including calls and social media app monitoring, tracking browser history, and GPS location.

Simply visit their website to register for a free account. When you’re done, pay for a subscription to get the download link and instructions on how to install the app on the target’s phone. 

How to Choose the Best iPhone & Android Spy Software?

If you wish to try an app other than the ones we listed, you’ll need a guide to help you make the best choice. Here’s what to look at when choosing a spy app to monitor Android and iPhone.


We can all agree that spy apps are highly sophisticated hacking software, so it’s no surprise they don’t necessarily come cheap. Yet, you can find apps like mSpy that are quite affordable and provide all the features you need to track your target. That said, be careful when selecting apps that claim to be free or offer a ridiculously low subscription fee. Many of these apps have been found out to be the work of scammers.


There’s no reason to pay for an app that’s not compatible with the device you’re trying to hack. Therefore, it is important to check for phone compatibility before buying a spy app.


The best apps have the best features. Be sure your preferred spy app has features that can allow you to spy on social media apps, calls, GPS location, text messages, and a keylogger, if possible. These are the core features that make up a great spy app.

Customer Support

If you’re using spy software, you may come up against minor issues from time to time. Hence, it is important to have the app’s customer services at your beck and call.

User Reviews

Always look up online user reviews of the spy app you’re buying. It’s easy for software companies to talk up their products, but an app is not great until the users think it is.

Final Thoughts

Although the apps listed above work on both Android and iPhone devices, you may find that some of them do not support specific models. This is why you need to check the app’s website to confirm that it is compatible with the target’s device. With that sorted, you should have no problem getting a spy app to monitor someone’s iPhone or Android device.
