I've been searching for an app that shows who viewed your Whatsapp profile. I didn't find one, is there such an app that tells you who saw your Whatsapp < last seen at...> ??
When did someone last see your profile?
This functionality is built in to WhatsApp itself so you don't need another app to get this information.
Who viewed your profile?
viewing your profile, I assume you mean someone long tapped on your name and then clicked
No- there is no app out there on any platform (not just Windows Phone) that provides this functionality.
You are not the only one- there is someone else who also wants this functionality. I wouldn't hold my breath though- I have my doubts about if even WhatsApp has this data.
