If you are looking for the primary cell phone monitoring software, Appmia will fit the bill. The main users of this product are guardians, bosses and partners who want the truth if they are being faithful or not. While this software has omitted some of the tracing applications, it does fine in others areas.
The software works in stealth mode so it is undetectable on the marked phone, as the feature will never appear in the lists or communications screens. You need to remember you have to be the owner of the phone in order to set up the application without the user knowing. Also in some instances you are required to get the agreement of person using it or you can end up with legal penalties.
