I use this for my child and it works pretty good, better then mspy. Its had its hiccups because my daughter uses cell data and not wifi. So make sure the persons phone uses wifi. Also you will need a converter to listen. I do wish they had live chat available more because sending in a ticket isnt always helpful. But it is more reliable then most deff do your homework because there are a lot of key factors you need to know how to use. Also you will need a second phone.
