Mark Zuckerberg has announced that the first WhatsApp smartwatch app is now available on Wear OS (Please refer to screenshot below). Rolling out from today, now you can start new conversations, reply to messages, and take calls — all from your wrist. Available on watches that run Wear OS 3, users will no longer need their phone with them to stay connected, and can respond to friends and family using their voice, emojis, quick replies or text.
