I try to use this app to track my children iPhone and guess what a surprise 1st they charged your credit card and later when downloading the application you will be aware that even that you have the username and password there is no access to the phone unless you make your children aware that you're trying to track their phone. Later when you want to recover your money for no service they just deny to give a refund because you agree with their terms even knowing that they can't fulfill the job and should make a refund. These people are a SCAM... trust me.
We say clearly you need physical access to the target device but you don't need to make your kid aware of anything to receive data. If you mean the tracking using iCloud account it is not available more than a year and it is not available on our website anymore because of this so what you say just don't make any sense
