A spy app helps you monitor messages received or sent, calls made, messages and media exchanged on WhatsApp, Facebook, and dating apps such as tinder. But most of these apps are easily discovered by the device user and removed. So, we recommend using a spy app that’s not easily detected. But what are the best undetectable spy apps?
mSpy is the best spy app that’s undetectable. It can be hidden on the target phone even if the device is not rooted or jailbroken. Besides, the pricing is fair. Asides from this, Flexispy, Guestspy, Spyera, and HoverWatch are other worthy options.
In the rest of the article, you’ll find out the review of these apps, their features, pricing, pros, and cons.
1. mSpy

Key features
- GPS locator function
- Environmental listening app
- Keylogger for smartphones
- SMS tracker
First on the list is one of the most popular mobile spyware. The spy app is available for smartphones, desktops, tablets, and iPads. The mSpy app is completely undetectable without jailbreak. It’s installed on the target device without being seen in the list of apps or as an icon.
The app lets you track your employee or children’s location remotely. You can view their current location and data like latitude, longitude, and address. When you activate the GPS history function in the settings, you can check the history of the last visited locations.
It allows you to monitor social media apps like WhatsApp, Facebook, Instagram, and other popular apps. mSpy can record every key pressed on the device of your children, employees, or others. This feature helps the user to find out the password of other apps installed on the device or to keep track of Facebook and other passwords. Therefore, the user can also log into the account of any social network of the target.

2. Flexispy

Key Features
- Ambient Listening

- Listen to environment
Like the first app, Flexispy is an undetectable spy app that works in invisible mode. It is also compatible with all devices. The software is, however, more affordable than mSpy, and users are impressed with the range of features with which it is easy to spy on a smartphone.
The invisible mobile spy application runs in the background and remains hidden from the eyes of other users. Many features of FlexiSpy are getting good marks. Features like GPS Tracking, IM Chat Tracking, and Password Cracker are among the most valuable features.
You can try the demo and see for yourself how it works. Ease of installation and multi-platform are unique features that made it worthy of being in this ranking.
The premium version is the best one as it offers a great compromise between price and features. The program was released to the general public only a few years ago. And in that short time, it has become one of the best spy apps on the market.
Pricing
- Lite plan: $29.95
- Premium plan: $68.95
Pros

Free and undetectable, GuestSpy has all the built-in features you need to monitor phone users. Like other apps, it is also effective for spying.
GuestSpy’s simplicity has made it even more useful for non-tech-savvy people. Most of the positive reviews come from parents who have tried this activity tracking app for their kids.
GuestSpy’s remote control feature lets you easily control the target device without contacting them. Real-time tracking and easy access to target information in the dashboard – are some of the 7things that impressed users.

4. SpyEra
Key features
- Live call listening
- Stealth mode
- Hidden GPS Tracker
This is new software with excellent monitoring features to keep track of your spouse’s, child’s, or employee’s activities. It can be used to spy on any phone and listen to their phone calls. The app can also help track GPS locations.
The app is 100% undetectable, according to the manufacturer. However, the spy app has several disadvantages, despite having exciting features such as ambient listening, call recording, location detection, etc.
The user cannot block certain content from the web, which turns out to be unable to control children’s behavior on the Internet. Instead, SpyEra actively monitors what is happening on the target device.
Pricing

- Smartphone plan: $89
- Tablet plan: $69
- Computer plan: $49

Another one of the best undetectable spy apps is HoverWatch. Specifically, this spy software provides all necessary features for spying on smartphone devices.
It screenshots the device now and then so you won’t miss details on any call, messaging, or online activity of your child or other users on their mobile.
The target will not even realize they’re being spied on. Hoverwatch will take photos of the environment using the phone’s front camera.
Pricing

Conclusion
If you want to spy on someone, there’s a high chance they’d discover the app and uninstall it after a couple of weeks. With an undetectable spy app, this would not be possible as the app icon would not be visible in the settings or app list. All the apps mentioned above are top-notch and work incredibly well with Android or iOS devices.
