How to Know Someone’s Online Status on WhatsApp without Any App:
From the following methods you can know this thing:
1. When the Person Reply

If you want to know someone’s online status on WhatsApp, you’ll need to send messages to her so that he can reply to the message when he sees it. You need to wait for the user’s reply as the user can only reply to messages after she comes online and checks them.
But if you’ve muted the person or your WhatsApp notification is not turned on then, you’ll not be notified about the user’s reply to your message. Keep notifications turned on for WhatsApp.
Even if you find that your message is not getting delivered immediately, it’s because the user is not online at that moment. Wait for the message to get delivered which you will be able to understand by seeing the two gray ticks. After you receive a reply to your message from the person, you’ll be able to see the reply in the notification panel.
Once he replies to your message, you’ll be able to understand that the user is online on WhatsApp at that moment. But if the user chooses to not reply to you intentionally, then you need to follow some other methods to check it.
2. From WhatsApp Group Activity

You can also find out whether a person is online or not from group activities. If you’re in a group with a user whose online status you want to know, you can check if he sends any messages in the group or not. Seeing the group messages or activities, you’ll be able to find out who’s online at the current moment.
You’ll only get notifications for group messages only if you’ve turned on the notification on WhatsApp. If you don’t have the notifications turned on WhatsApp, you’ll not get alerts for group messages. Even if you’ve muted the group, you need to unmute the group to get notifications in the notification panel from WhatsApp.
Other Things to Know about Someone’s Online Activity:
You can tell from the below things too:
1. Typing Tag

Another thing that can help you know someone’s online activity is the typing tag. WhatsApp shows the typing tag when someone types a message to you. You can also see the online tag instead of the typing tag when the user is online on WhatsApp and has not started typing yet.
If you want to know about someone’s online activity, you need to look for the typing tag below the user’s name on WhatsApp which only occurs when the user is typing some message to you.
But if the user types after turning off the data or wifi connection and then turn it on before sending you the message, you’ll not be able to see the typing tag on the chat screen. However if the user doesn’t reply to you or leaves you reading, you’ll not see the typing tag.
2. From Recent Status Viewers
Even from the viewers’ list of your status, you’ll be able to see who is online at the current moment. You need to upload the status and then wait for a few minutes. Next, check the viewers’ list to see who has viewed it. The ones who are viewing the status at that moment will be labeled as Just Now.

Other than that, you’ll be able to see the time of viewing the status under every viewer’s name. If you see that the user has the Just Now tag, or is showing the most recent time, it’s because the user is currently online and is seeing your status.
But if your read receipt is not turned off, you’ll not be able to see the viewers’ list of the status. You need to make sure that you’ve turned on the read receipt before uploading the status. However, if the viewer puts his read receipt off before seeing the status, his name will not be recorded in the viewers’ list although he has seen the status and is online.
Frequently Asked Questions:
1. How to know if someone is online on WhatsApp without opening the chat?
If you want to know whether a person is online on WhatsApp, you need to open the WhatsApp application and then search for the user’s profile by entering his contact name.
Next, you need to click on the chat. Then click on the profile name at the top bar of the page and it will open the user’s WhatsApp profile. If you see the online tag under the user’s name, you’ll be able to know that he’s online.
2. How do I know if someone is checking me on WhatsApp?
