Apple watchOS beta 4 is looking good

Apple watchOS beta 4 is a huge improvement over beta 3!

Here’s things I’ve noticed already:

1. Apple Pay is now enabled.
2. The screen brightness at maximum has improved.
3. Animations are very smooth again. Beta 3 was extremely slow.
4. UI bug with customising a watch face while time travel is enabled fixed.
5. Apps appear to load faster.
6. Siri isn’t as slow as Beta 3 but isn’t as fast as watchOS1 or iOS9 (Siri on iOS9 dictates word-by-word in almost realtime like Google Now).
7. Wrist detection for turning the screen on now works when you’re lying down!
