It is true that there are alternatives such as using WhatsApp Web within these devices; however, the experience may not be as expected.
The truth is that this is about to change thanks to the arrival of the Multi-Device Mode to WhatsApp. This feature has put on the table the possible existence of an official version of the service for tablets and now, everything seems to indicate that we are perhaps a few months away from testing it.
This mode is now about to receive one more option to use the same WhatsApp account on both a smartphone and a tablet at the same time.
WhatsApp is getting ready to reach your tablet
As can be seen in a shared screenshot, the user interface is shown adapted to the horizontal format of a tablet, while adding the option to scan a QR code with the main device to associate the account.
By completing this process, users will be able to take their chat history to the tablet and use the messaging service from said terminal, even if the main device is not connected to the network.
For now, this possibility remains in a development phase, so there is still no approximate date for it to land in the stable version of WhatsApp. However, the official version of the service for tablets is closer than ever.
