WhatsApp is set to introduce multi-device support to its application soon. This means that users will no longer need to ensure a ‘main’ device in order to sign in to WhatsApp into another account.
In a nutshell, tablets and iPads will receive a fully native WhatsApp application soon. This information was leaked by WABetaInfo in a recent tweet where it was mentioned that users will be able to use iPads and tablets as linked devices that would run independently without the need for a smartphone.
