The Palette face depicts time in a wide variety of colors using three distinct overlapping layers, and as time changes, the colors on the display also shift. Additionally, the beloved comic strip Peanuts comes to life on Apple Watch with a new watch face featuring Snoopy and Woodstock. The characters interact and play with the watch hands, react to the weather conditions in the area, or even get active when the user does a workout.

My Experience with watchOS 10 Developer beta

watchOS 10 developer beta works fine, everything is working. However, I have noticed a few stutters or lags when opening the new Smart Stack feature. One thing which I didn’t like about the watchOS 10 first beta is, the battery experience. Based on my usage, the battery backup has significantly decreased compared to the stable watchOS 9.x version.
