I am using XNSPY from almost 6 months and I face a lot of difficulties in the start to make this app work but failed every time.
I want to appreciate the support staff the way they helped me in that time. They all helped me to get it fixed. But Katie Ford is the one who helped me last time with the installation and believe me. Its never stopped working from last 3 months and I really appreciated her knowledge for the phones. Seriously Katie people like you are hard to find and lucky to have. I will suggest EVERYONE to contact her to solve your issues. She is the master of this monitoring stuff.
