Great, but......

If one tries to enter a reminder for the current day, it shows up on the watch for tomorrow and on the phone for today. If you try to change it, it still maintains the difference.

There is no provision for unscheduled reminders on the watch. It will import unscheduled reminders to the phone app from the Apple app. However they will not appear on the watch.

Suggest getting rid of that useless timer screen on the watch and put unscheduled reminders there.
