Glance:The quickest way to access your to-dos is by pulling up Things’ Glance — just raise your wrist and swipe up on the watch face. There’s also a nice little graph that tracks your performance over the past few days.
App: Quickly mark your to-dos complete as you go. Each accomplishment doesn’t go unrewarded: there’s a nice animation as you check off your items, and the ring at the top inches forward as you progress through the day.
Using Siri: Just press and hold the digital crown, or say “Hey Siri, remember to contact Sarah about our trip”. This sends the new to-do to Things’ Inbox where you can process it later.
Inside the app: You can also tap the + button to dictate your to-do. If you want to work on it right away, move it from the Inbox to your Today list with a quick tap.
Focus on a project: If you know you’ll mostly be working on a given project throughout the day, you can simply mark that project with a star on your Mac, iPad, or iPhone and it will show up on your Apple Watch.
Notifications: To get reminded about scheduled to-dos in the morning, just turn on Notifications in Things’ settings on your iPhone, and choose a time for your alert.
Dictate notes: Not only can you read your to-dos’ notes, you can even add new information on the go through dictation.
