The app does exactly what it claims. It operates in stealth mode so another person can't find out they're being spied on. You can monitor everything from calls and texts to browsing history, location, and more. After installation, it takes about 24 hours for the data to sync to the web-based account, but once that's done, spying on the phone's activity is a breeze. It really is that easy and very affordable, unlike other spy apps.
