A mobile spy tool allows you to monitor a mobile phone's activities and communications without the phone user's knowledge. It records all activities on the phone such as calls, texts, emails and browser history and transmits this information to the person who installed the spying software. Mobile spy tools are useful for monitoring employees, children or partners who you suspect may be behaving dishonestly or inappropriately on their phone. The spying software works by installing itself on the target phone and operating in the background without leaving any traces of its operation on the phone.
