You’ll need to invest in an app like mSpy. First, pay for your subscription (you’ll want to choose the version that comes with ambient recording). Then, check your email for installation instructions for the device you want to monitor. Simply follow those instructions to get up and running with mSpy on their phone. When you need to record their surroundings, just log in to your mSpy Control Panel and activate the microphone. When you’re ready to listen to your recordings, just head back to the Control Panel. They’ll be there waiting for you to review.
