WhatsDog, the WhatsApp’s WatchDog
Hello! My name’s WhatsDog and I’m your WatchDog. I’m going to warn you when the contact that you choose connects to WhatsApp.
You are going to catch him/her online and he/she is not going to notice that is under surveillance thanks to WhatsDog.
You’ll be able to text your contact immediately and he/she won’t be able to tell you that he/her didn’t see your WhatsApp message.
