In my humble opinion, it is not possible with the current WhatsApp infrastructure to track down visitors who have been specifically seeing your WhatsApp profile (example looking at a picture, watching status updates)
I got fooled by a junk app called WhatsApp tracker or whats tracker that assured me that it will display new visitors to my profile. Turns out this is totally false. I am not sure with about the logic behind the design for it to accomplish this function.
Really folks, is this possible? Is the above mentioned app genuine? I did not find it so... But if it is even scarcely, then what logic helps to track down visitors?
