Improved Camera Remote App
Apple made some small improvements to the camera remote app on your Apple Watch. Now, you’ll see you have the option to turn on the 3-second timer right on the center of your Apple Watch display.
You can turn the timer on or off using the new options button. There are other options available there as well, such as turning on your flash, switching between the front and back cameras, and turning Live Photos and HDR on or off.
