SpyX is a legitimate app that you can use to monitor your kid’s device. That said, there are several things that SpyX isn’t entirely upfront and honest about. For example, its website heavily advertises that you can use SpyX without installing an app on your kid’s phone, but this is only true if you’re willing to accept a more limited set of features.
There are features shown on its website that don’t exist. Plus, the demo that’s available on its website is a poor representation of the actual product that you get.
