To monitor your child’s Snapchat, you need to use a tracking application. It allows viewing Snapchat remotely from any device a customer uses to access the Internet.
You need physical access to an Android target device to set up an app. To get started with an app on an iPhone and other iOS devices, you don’t need to take a phone into hands if you have iCloud credentials and iCloud is enabled.
Once installed, you log in to your personal account provided by the app-related service and start monitoring any promised feature, including Snapchat.
