Spyier is another option which you can use for monitoring WhatsApp. This spy app is relatively cheaper than other apps, but it is not fully loaded with all features. In any case, it is a handy app to use for doing essential spying on WhatsApp. Jailbreaking or rooting the phone is not necessary, and the app is simple to use. It also functions well both on Android and iOS devices.


With Spyier, you can read someone’s WhatsApp messages without their phone. To see them, you should log into your online web panel and choose the WhatsApp section for monitoring. There you will be presented with all necessary info about who and when has sent or received the message on WhatsApp. In this section of the control panel, you will also get details about all other files that have been shared through WhatsApp, so you will always know what is happening. Some additional features found in Spyier include tracking of phone contacts, calendar, browsing history, social media and GPS tracking.

In general, Spyier is convenient because rooting or jailbreaking is not needed, but functions are variable based on which operating system is being used. The price of the app is also a bit higher than other apps, starting from $39.99 per month and going upwards.


FlexiSPY is a working WhatsApp spy app that does not only show the conversations from this social app but also the contact profiles in the monitored device. With FlexiSPY you can see when the monitored user is exchanging the contact details, locations and other things with another contact on WhatsApp. Everything else that is shared on WhatsApp such as multimedia, documents and attachments will be shown directly to you on your dedicated user portal.


To use FlexiSPY both rooting and jailbreaking the phone is necessary if you want to perform WhatsApp spy. Despite some positive characteristics, there are a few cons associated with FlexiSPY. It is considered quite an expensive spy app because the one-month plan starts at $68. Besides that, manual installation is required, and some options go beyond legit boundaries.

Mobile Spy

Mobile Spy is a top app for parents who are just figuring out how to spy on whatsapp messages without target phone. Interestingly, this app is not really a spy app in its essence. The user of the targeted phone has to give consent for the app to be installed because the app shows up on their screen. So this is basically a monitoring app designed for tracking children’s WhatsApp behaviour with their consent. It is more of a monitoring app than a spying app.


MobileSpy requires jailbreak and root so you can monitor the device, but using the app is really easy. One simple thing to do is only click on the WhatsApp tab in the app, and you will monitor everything, such as received and sent messages, chats and shared files. You can even download some video or audio files directly to your online panel.


GuestSpy is the final WhatsApp spy app that really works. This is a popular app because the monthly package for using the app starts at $16.99. Jailbreaking and rooting are both necessary for unlocking the WhatsApp spy features of the app. The list of features of GuestSpy is decent, with many excellent options available for you to use.

If you are a first-time user, then you will have no trouble using this app. The software is intuitive and user-friendly, and in the app, you will find different tabs for WhatsApp conversations and for sent and received messages. GuestSpy will show you the name of contacts in WhatsApp, their number and also the date and time stamp. There is a separate tab for monitoring audio files, pictures and videos directly on the control panel of the software.


Pros of this spy app include simplicity of usage, a 2-day free trial period to test the app, and good user-interface. Cons of this app are that it comes with some bugs and glitches that prevent it from functioning correctly, call recording is only available in the most expensive plan, and the basic idea does not come with all features.


We have thoroughly evaluated all things necessary to come up with the best solution. Based on the essential criteria, we have found that NEXSPY is the best choice to use for hack someone’s WhatsApp.

Besides these, there are a few other monitoring software out there, but not all deliver everything as promised. NEXSPY stands out from the rest because it has shown proven good results in monitoring, tracking and recording everything regarding WhatsApp.

It is a powerful app packed with powerful features at an affordable price. We are confident that you will be satisfied if you choose to use this software.
