Since this app is the leading messaging app, there have been many questions surrounding this app on the features, and in this article, I am going to take you through WhatsApp features and how they work.
Checkmarks In WhatsApp And What They Mean

The checkmarks in WhatsApp let the sender know whether his or her message has been received. One checkmark means that the message has been sent, but the recipient is not online or connected to the internet.
Two checkmarks mean that the message has been and delivered to the recipient’s phone.
The double blue check marks mean that your message has been delivered and the recipient has read the message you sent.
A red exclamation sign means that your message has not been sent, probably because you don’t have an internet connection.
There is an exception for the checkmark.
You can have a double checkmark even though you see the recipient online for a long time after you sent the message.
When this happens, it means that the recipient has switched off their read receipts.
In this case, they will read your message, but there will not be a double blue checkmark. This is usually used by people who want to avoid replying to some messages.
Last Seen

You can hide the last seen on your WhatsApp by going to the settings menu, then going to account, and then privacy.
You can then switch the Lasts seen between everyone, my contacts, or nobody.
