With watchOS 9's release coming up, Wristcam is getting a bit of an upgrade. According to Mark Gurman's Power On newsletter, the Wristcam's third-party app on the Apple Watch will allow you to receive video calls from an iPhone without the Wristcam attachment. This means you can send audio and receive video from the other person in the call without sending back video. Wristcam is a niche accessory that adds a video-chat camera to the Apple Watch.
