The official WhatsApp app is now available on the Apple Watch for everyone, following a brief beta testing period via TestFlight last week. The app allows you to send messages, read full messages, send message reactions, record and send voice messages, receive call notifications, and more — all directly on your Apple Watch, with no need to take out your iPhone.
Props to this small indie developer who’s worked tirelessly to launch this relatively unknown app promptly on Apple Watch
