3 Best Phone Tracker Apps Without Permission 2021

Tracking a phone is no longer a fantasy thing, it came out from Hollywood thrillers to everyday life long ago. Today, you don’t need to be an FBI or CIA operative to track someone’s phone by phone number; you can easily do that with apps that are readily available for you to download.

With the rapid technological expansion in the smartphone industry, this phone tracking technology is far more sophisticated and accessible than it was ever before. However, with an abundance of such new phone tracker apps, and their never-ending feature lists, it can be a little overwhelming for us to choose the best one.


Hence, we decided to put up a few such apps in this article and compare their features, prices, etc. so that you can decide which one you should go for. So, without wasting any more time, let’s get started in our quest to find the free cell phone tracker app.

How to track someone’s location without them knowing?

For tracking a cell phone location for free on an Android or iPhone, you must make it installed on that device first obviously. And to install the app, you have to have the phone on your hand (because obviously the victim won’t install a spy app on his/her smartphone willingly knowing what it does), and do it yourself.

Theoretically, you can inject a spy app by sending it as a payload attaching with an innocent-looking image file through WhatsApp or other messenger apps. Once the person taps on the image file, the hidden payload will start installing itself in the background without alerting the victim.


This is possible in theory, but as you can clearly see that it won’t work most of the time because too many factors are involved.

Top 3 Best Phone Tracker Apps Without Permission

Using a phone tracker app probably the easiest thing one ever did on a smartphone as it doesn’t need any intervention to work, it’s like ‘set and forget’. Once you install it, it will start working on its own and will continue to monitor every possible activity being carried over with that phone.

Unless, of course, the victim does a factory reset, in that case, the spy app will be removed from the phone, and you have to install it again on the target phone by accessing it physically.

It’s up to you what you want to monitor with such apps as most of the known phone spy apps track almost everything you ever need. From call interception to SMS, from camera photos to the file manager, from the contact list to browsing history, from instant messaging (WhatsApp, Snapchat, etc.) to real-time location, each and everything can be tracked by a good spy app while hiding itself inside the phone.

The target phone needs to be connected to the internet by Wi-Fi or mobile data for you to receive the tracking update as an offline smartphone can’t be tracked obviously. 

Here we will discuss a few popular tracking apps and will compare their features, prices, etc. so that you can take an informed decision while selecting the best app to track phone without them knowing. So, without further ado, let’s get started.

How To Choose The Right GPS Tracker?

Device compatibility

All three apps are compatible for both Android and iOS; hence, device compatibility shouldn’t be an issue regardless which app you select. NEXSPY works on both PC and Mac along with mobile devices giving it a bit edge over the other two apps in the compatibility section.


Price comparison

All three apps mentioned above are premium apps, and they cost monthly/yearly subscription fee. So, people who just want to have some “fun,” can look for other free apps to track a cell phone location that have far fewer features – these apps in our list are for those who have serious needs and don’t mind to pay the price.

The first app, mSpy, has three packages starting from $29.99 and can go up to $69.99 per month. The pricing structure of mSpy is a bit complicated, it’s better to talk to a live support agent on their site to decide the best package for you.

NEXSPY – our second contender, has a more straightforward plan of payment based on monthly, quarterly, and yearly – which starts from $19 per month only if you go annual basis.

The last app from our list is Hoverwatch, and it will set you back for a minimum of $8.33 (personal plan, yearly basis).
