How to Know when Certain Contacts Come Online in WhatsApp

This article is meant to show you the best methods to learn when someone signs in on their profile for WhatsApp. There are three main methods for this, one that is just for Androids, one that is just for iPhone, and one option that works on any platform.

How to Get Notification When Someone is Online on Whatsapp

Hello everyone! It is your dear friend Frankie here, “the Boss of WhatsApp” (I kid). If you want to overcome end-to-end encryptions and encrypted call connections and learn when certain contacts connect to WhatsApp, you can find it here – even if they are trying to keep this information a secret.

There is little that users can do to hide their presence completely on WhatsApp. Even with specific tricks people use to become invisible on the service, apps I am introducing you to can bypass these tricks and give you the information you want.

So, let’s not waste any more time.

Let’s begin with viewing someone’s last seen information – even if they have taken measures to hide it.

What I have listed below is what I believe to be the best options for monitoring activity on WhatsApp. You can even get a daily report of their activity for some of these options.


  • WhatsApp does not come with any feature that allows users to set up notifications that alert when a contact is online or offline.
  • There are several WhatsApp Trackers that show you when a contact is (or has been) online. They work on both iPhone and Android.

Frankie’s Take:

I have personally tested these options. I’m always looking for alternative techniques, so if you have found any on your own that you are sure that work, you can share it with all of us and it will be greatly appreciated.

Method #1 – mSpy WhatsApp Tracker [100% Reliable]

Getting started:

  • Your victim’s mobile phone at hand for a few minutes
  • No Jailbreak for iPhone user or Root on Android
  • License for mSpy (25% OFF)

This is unlike the previously discussed methods in that this is 100% safe, working, and reliable.

This is one of the most popular spying apps ever created. It is simple to install and operate, and features a user-friendly interface for collecting information as it arrives.

Even better, the software works with a continuous available customer service team accessible through email and chat 24/7.

mSpy works on iPhone and Android platforms, and does not require secondary actions like rooting or jailbreaking to accomplish.

You can have the software installed in a matter of minutes, even without technical skills.

Here is what you have to do:

  1. Purchase the license from the mSpy official site (and by clicking HERE you can get an additional 25% offit’s the best I could do)
  2. Access the target device (both platforms) and install the app. It is possible to install remotely on iPhone if you know iCloud login credentials.
  3. Settle in for a lot of information to know what your target is doing and when – no matter where you might be in the world.

Hack WhatsApp with mSpy

Learn more about the installation through a step-by-step guide I wrote about mSpy – the Best Cell Phone Tracker App. Inside you can find a discount voucher for the software exclusive for readers of my blog.

Note: mSpy is completely invisible, so your target will know nothing about your spying.

Once the software gets installed, you can have access to a substantial amount of information. You can learn about their WhatsApp activity, track SMS, see internet browsing history, emails, saved media, instant messaging information, and much more.

If there was a drawback to mention, is that it might work TOO well. Many of relationships and marriages have been ruined by discovered information.

If you want to learn a bit about this software, you can see a free trial to learn the dashboard and get introduced to the features.

This has to be what you are looking for, right?

✅ 100% effective

✅ User-friendly interface

✅ 24/7 Support – (you can also choose mAssistance for them to install the program for you for a fee)

❌ Fee-based

❌ Only tracks the one target phone and not multiple contacts

Method #2 – ChatWatch Whatsapp Online Tracker [98% Reliable]

Getting started:

  • Get notified when someone comes online on WhatsApp
  • License for ChatWatch (very cheap)

ChatWatch is definitely the best WhatsApp online tracker out there. Unlike mSpy though – which allows you to spy on your victim’s WhatsApp account in full – ChatWatch just reports through a notification when a number is online on WhatsApp.


Its operation is extremely simple. All you’ll have to do is:

  1. Access ChatWatch
  2. Sign up by entering your email and choosing a password
  3. Purchase one of the three available plans (Weekly $2.99, Monthly $9.99, Yearly $79.99)
  4. Scan the QR code (you can add up to 3 phone numbers).
  5. Wait for login notifications on your device. Notifications will be sent to you through your Telegram app. Meanwhile through your dashboard you will be able to view insights with your contact’s daily accesses.

If you like, you can use the program for free for 8 hours.

A feature that I found very handy about ChatWatch is Chat Probability.

Let me elaborate.  

Thanks to this feature you will be able to predict the probability of two of your contacts chatting to each other, simply choose any two numbers from your contacts list. Chatwatch will compare them to tell you exactly how their chat activity compares, if they have been online at the same times, and much more.


✅ 98% effective

✅ User-friendly interface

✅ Chat probability

❌ Fee-based

❌ You can track only 3 numbers

❌ Does not allow you to access your victims’ WhatsApp chats

Method #3 – WhatsApp Trackers (Android) [60% Reliable]

Getting started:

  • Only works on Android smartphones
  • Root is not required
  • Get notified when someone comes online on WhatsApp

The next method is only for those using Android phones.

Yes, you can root this device similar to jailbreaking an iPhone. However, there are options that can be tried before this more intricate and complicated process occurs. There are apps available without rooting, but there are undoubtedly drawbacks.

Among the biggest issues is how readily they show up and leave the Google Play Store. One day you have an option, and then suddenly the app is non-existent.

It is also possible because they cannot rack activity that notifications do not occur for every instance where they occur.

There are a few names that work for right now, and they are able to be installed (at this time). WhatsDog (not available all over the world), WhatsAgent and Online Monitor (Last Seen).

Note: in most of cases you will not find them on Google Play but through alternative app locations. Sadly, apps like these do not get updated frequently, meaning that they might not always work on all Androids (especially new and updated Samsung devices). Still, it might be worth giving it a try.

Many of these apps are similar in look and function. Attach a phone number and you can get most updates about the activity of them coming and going from WhatsApp. If you are choosing free options, prepare to face some ads.


✅ Most of the time these apps are free

❌ They are not always effective

Legal and Ethical Considerations

Using tools to get notifications when someone is online on WhatsApp comes with legal and ethical responsibilities. Monitoring someone’s activity without their consent can violate privacy laws and damage trust in relationships.

Legal Implications

  • Privacy Laws: Unauthorized monitoring may be illegal in many countries.
    Consent: Always check local laws regarding consent for monitoring.
  • Ethical Considerations
    Trust: Spying can harm personal relationships.
    Intent: Ensure your reasons for monitoring are justifiable and responsible.

Best Practices

  • Obtain Consent: Inform and get consent whenever possible.
  • Use Responsibly: Only monitor for necessary and lawful purposes.

Respect legal and ethical boundaries to use these tools responsibly.

What makes mSpy the best option for WhatsApp monitoring?
mSpy is highly reliable, user-friendly, and doesn’t require rooting or jailbreaking your device. It offers comprehensive monitoring features and 24/7 customer support, making it the top choice for tracking WhatsApp activity.

Can I track multiple contacts with mSpy?
No, mSpy is designed to track one device at a time. If you need to monitor multiple contacts, you may need to purchase additional licenses or consider other tools.

How do I install mSpy on a target device?

The Take Away

You now have a much better idea how to get the information about your friends and family getting online with WhatsApp.

But, let’s do a short recap just to be safe.

The best way to know when someone gets online on WhatsApp is through mSpy. Thanks to mSpy you will not only be able to track your victim’s WhatsApp accesses but also read their chats and see the media files sent and received. You won’t risk getting caught and it’s very easy to use (however you have to have the victim’s phone at hand for a few minutes).

In second place I would rank ChatWatch. It is definitely the best WhatsApp online tracker currently available. It notifies you with a notification sent via Telegram when a contact is online. It’s secure, easy to use and cheap.

The next method that was discussed was using programs like WhatsAgent, WhatsDog, or Online Monitor (Last Seen) on your Android device to track activity. You cannot typically find these in the Google Play Store, but rather alternative download sites. WhatsApp does not like these programs and works to block them when they are discovered.

That is pretty much it.

If you are struggling getting these options to work or want more information, you can always reach out to me for some help.

A hug,

Frankie Caruso

    Thanks for providing those Tips. You are great are you there on Fb or Instagram. I want to follow you.

      • Can you find out if someone is online if they are in ghost mode or disabling using WiFi/data to appear offline and read messages. I have someone who is reading my messages, last seen 2 days previous, one tick appears for hours. Think they are online in a way chatting but blocking me from seeing they are active. They have android phone. I believe they are connecting and disconnecting to chat to a certain person. Would a spy app pick this up?? Or like OnLog or WaRadar. Any apps for Android to go incognito

  3. Hello Frankie,

    Nice Post and thanks for opening up new options in Watsapp
    I have tried to check on mspy for iphone but the app shown says its a lite version and tracks gps
    Nothing is said on watsapp online status notification or so.

    Please help


    • Hi Prem and thanks 🙂 You don’t have to download the app from the Apple store but you have to buy the software from the mSpy website. Online stores – like Google Play or Apple Store – are not enabled to sell this type of app because they affect privacy.

      • Hello Frankie, need your help, what is the best possible android mobile application that gives online offline notifications of a whatsapp number that has blocked you. Thanks.
