Day One iOS and Mac apps support URLs to send data into the apps from external sources. This allows apps like Launch Center Pro and others to work. Check out our amazing collection of user-created templates using these tools: Day One Templates.
Note: If you're using the Day One URL scheme in Terminal (or your preferred CLI app), you'll need to type "open" followed by the URL scheme. Also, if you have both Day One Classic and Day One 2.0 installed on the same device, the URL Scheme will route to Day One 2.0.
