Useless and expensive battery drainer

I tested the app to track my kid. Location updates are haphazard and delayed. The app is showing my kid at school while "find my iPhone" is showing her at home ! The interface is misleading as it pretends it has a current location fix when the data is hours old. Worse of all it kills my battery, my Iphone shows that the app is responsible for 50% of my power usage. I only use my phone to see where my kid is, I am not even tracking ! I guess it keeps sending its position to a server but I dont see how to turn that off. Add the crazy in-app cost per phone tracked and there is really no reason to use the app.
