Shake has caused the app to appear StealthGenie which after installing it on any smartphone allows remote monitoring of any activity.
The application is not traceable and collects detailed data about calls, messages and generally all the activities of a mobile phone, which it then sends in real time to a safe account without the knowledge of its owner.
Maybe this one service intended for legal use (monitoring of minor children, installation in corporate cell phones phones), however its huge appeal (it already has more than 100.000 subscribers) leads to the conclusion that it is probably mainly used abusively and against personal data (monitoring of spouses, etc.).
The application is already provided in Greece by the management www.StealthGenie.gr
