Most of the time, I capture items to Drafts on my Watch. I capture ideas, clinical questions, quotes, etc. My watch synchronizes the new item with my phone (in the Drafts Inbox). When I have a few minutes I can vector the new memo to the correct location using Action URLs.
Occasionally, I will capture items directy to Day One (although this requires the Day One also to be open on my phone). I maintain multiple journals: Personal, Professional, 3GoodThings, Social Media, and Accomplishments. I’ll capture to Day One if I also wish to capture the location the item took place. Most of the time, I just capture to Drafts.
Although I was a bit skeptical about the utility of my Apple Watch at first, it has become a useful tool both in my personal and professional life.
