Most spy apps are hidden but if they are not then they will directly appear on the menu of the phone or the homepage. Some apps also have notifications that show. So, check these common areas for signs of the app before handing it to the person you want to monitor?

Many spy apps come with a free trial or version that allows you to experience the app before committing to a full subscription. Keep in mind, though, that most of the features of the app will not be available in this free version and may be locked until you get the paid version.

All of these spy apps have many functions and features that can help you keep a close eye on someone who is being suspicious. Some of the common features among them include location tracking, message checking, photos and videos checking, checking social media accounts and much more.

The installation process of these spy apps is very simple although the process may vary slightly depending on the app you choose. You primarily need a main controlling device and a device to be controlled. Install the app on both the phones and use the controller phone to monitor your device of choice.

Each of these spy apps has a different set of features and functions. So, to find the best one for you, you need to understand which monitoring function is the most important for you. After you narrow that down, you can settle on an app that specializes in that function or feature.
