I have a series 4, and watchOS 10 is barely useable. The worst thing is how LAGGY it is. This scenario happens daily:

• timer goes off
• tap x to dismiss
• UI doesn’t respond
• tap again because I wasn’t sure if I hit the microscopic x or not
• timer clears and it buffers another tap so it automatically starts another timer

There is SO much lag with the timer app. It constantly freezes and queues up tons of tabs.

Borderline unusable.
