Keep track of family members, employees or anyone you need to monitor with keystroke logging (often called keylogging). The keys struck on a computer keyboard are tracked (or logged), typically in a covert manner so that the person using the keyboard is unaware that their actions are being monitored. Monitoring someone of interest can also be done via their mobile phone. For example, it can be rather stressful parenting a teenager. However with mobile tracking apps, you will know whether your kids are safe. Messages to and from your children, GPS data of precise whereabouts, and even restriction of calls from suspicious contacts will be very beneficial.
