WhatsDog is a simple tool to tell you when a contact gets online on WhatsApp, even if he or she has made that information private. With this tool, you'll be able to spy on any phone number you want.
You don't need to have WhatsApp installed, nor even have the person saved in your contacts book. The app only requires a phone number to start tracking, and once it does it will give you detailed information about when that person gets on and off WhatsApp.
Once you start using this app, a calendar will be created where you can see the entire history and statistics related to tracked contacts' connection times. This way, you'll be able to know how many times he or she got online in the past 24 hours, the past week, or even the past 30 days, and also exactly for how long.
You can also configure WhatsDog to notify you at the exact moment the number goes online.
