While Cathcart wouldn’t go so far as to commit to the release of an iPad version, his comments suggest it’s possible that one will be built in the near future, especially now that WhatsApp has built the underlying technology needed for such a client to work.
Because of the way WhatsApp encrypts messages, it historically hasn’t been able to sync chats across devices over the internet like most other messaging apps work. So if WhatsApp on your phone didn’t have access to the internet, the desktop client didn’t work.
The beta version of multi-device support lets you sync your WhatsApp account on up to four devices at a time, a process that involves mapping device identifiers to an account key on WhatsApp’s servers in a way that’s still encrypted.
Now that such syncing technology exists, there’s a good chance that WhatsApp for iPad is finally on the horizon.
