What Are the Features to Consider Before Buying a Mobile Spy App?

Various spy apps do hold promises of advanced monitoring capabilities. However, there are vital features that are non-negotiable when choosing a mobile spy phone app. Putting these features into consideration reduces the chances of buying an inefficient app.

  • Compatibility

When considering the app’s compatibility, you’re checking whether the spy app works on the target device. While some apps like mSpy work with rooted/unrooted or jailbroken/non-jailbroken devices, others only work with rooted/jailbroken devices. Also, you have to check which Android or iOS versions the app supports. That way, you won’t end up purchasing an app you can’t use.

  • Location Tracking

One of the most crucial aspects of remote monitoring is location tracking. Whether you want to track your kid’s location or keep tabs on your partner’s whereabouts, you need the GPS location feature. So consider getting an app that offers accurate information on the real-time location of the target.

With even more advanced features, you can set up virtual boundaries for your wards. The app sends you instant alerts once your child crosses the predefined geographical limits.

  • Call Log and SMS Tracking

Without a doubt, call log and SMS tracking are the top features people look for in a spy app. A good spy should let you keep track of all incoming and outgoing calls of the target phone. You see who your person of interest is talking to, how long, and how often. The timestamps show you the date and time the calls are made. 

With the SMS tracking feature, you get to read sent and received messages. It would help to get an app that lets you view deleted text messages. 

  • Ability to Work in Stealth Mode

The purpose of using a monitoring app is to track a person’s activities remotely. So it’s essential to use an app that works in stealth mode. After installation, the app captures and sends data to the cloud-based server without being discovered. That way, you can spy on the phone without fear of being found out.

  • Pricing 

Spy apps come with different subscription prices. Before spending your money on any, consider how much value you’d get for your money. With higher prices, you’d expect more advanced tracking solutions. However, some more affordable spy apps offer better remote monitoring capabilities.
