Overview
WhatsDog is an Android utility that monitors WhatsApp activity for any phone number supplied by the user. The app records login and logout events even when the target account is set to private and does not require WhatsApp to be installed on the monitoring device or the number to be saved in contacts. It builds a calendar view that shows how many times the monitored number connected in the past 24 hours, the past week, or the past 30 days, along with the total minutes spent connected during each period. A notification can be set to alert the user the moment the number comes online. All data is stored locally so the user can review historical records without staying logged in continuously.
What You Can Do
⭐ Enter a phone number to begin tracking its WhatsApp connections and disconnections without needing the app installed on the device or the contact saved.
⭐ Receive a notification on the device the instant the monitored number logs into WhatsApp.
⭐ View a calendar that displays the full history of connection times and calculates how often and for how long the number was online over the last day, week, or month.
⭐ Access a list of recent WhatsApp connections and disconnections sorted by date and time.
⭐ Review statistical summaries that indicate the monitored number’s overall connection frequency and duration patterns.
⭐ Open a direct button inside the app that launches WhatsApp if the user also has that messaging app installed.
Using the App
The workflow begins by opening the app and entering the target phone number. Once tracking starts, the app automatically records every detected connection event and organizes the data into a calendar format. Users can scroll through daily, weekly, or monthly views to see exact login times and total online duration. Notification settings allow the user to choose whether alerts arrive silently, with vibration, or are turned off completely. A donation option removes advertisements. The app supports sign-in with multiple Google accounts for backup of tracking data. No device rooting is required because the monitoring relies solely on the supplied phone number.
Why It May Appeal
✅ The calendar and statistics features give a clear overview of usage patterns without requiring constant manual checks.
✅ Tracking works for any number in the WhatsApp system, even if the account shows no recent contact history to others.
✅ The interface remains simple: only a phone number is needed to begin monitoring, and the resulting logs are presented in an organized calendar.
Things to Consider
❎ The app displays advertisements unless the user makes a donation to remove them.
❎ Historical records are limited to the periods the user has actively tracked; earlier activity before tracking began is not available.
