We had developed TheTruthSpy (since 3 years ago) to make the parent take care of their children or to let someone find the true from cheating spouses. Almost our customers are happy. Maybe the price is a little expensive than other products but we offer 3 devices for 1 account (Other products offer 1 device for each account).
So in the end, we have a lower price compared on multiple devices. If someone wants to use more or less number of device please contact us at firstname.lastname@example.org. After installing TheTruthSpy application on their target phone(s), they must visit thetruthspy.com to view the log (SMS History, Call History ...). Every time they visit they must enter their account and after viewing the logs they must do an action "clean history" of browsers (Safari for example) because they do not want to let a chance for their target (their children) know about being tracked.
So, we decided to develop TheTruthSpy Monitor application as server version ('monitor' version) of TheTruthSpy (client/target version) to let them view the data logs without accessing the user control panel website https://my.thetruthspy.com. Let's install it on your device (parent's).
