About Plume

Plume: A Health Journal is a health journal for iPhone and Apple Watch, made by Yingjie Yu; this page says what it is, the ideas behind it and how to get in touch.

What is Plume?

Plume is a journal for food, sleep, mood and energy that you keep in your own words, by typing, talking or taking a photo. After about a week it points out patterns from your own days and can set up small experiments to test them. It is a wellness journal, not a medical device.

Who makes Plume?

Plume is made and operated by Yingjie Yu, the name on its Privacy Policy and Terms of Service. A person reads every message sent to help@plumeapp.net.

What ideas is Plume built on?

• Capture without forms. Text, voice, photos and the Watch all go into one entry, and nothing has to be put in a category.
• Honest numbers. Patterns are checked by code against your own days before the app words them. A correlation is called a correlation, and thin data is called thin.
• A small next step. A pattern can become an experiment, and the result is set next to what you expected.

Is Plume related to other apps called Plume?

No. Plume: A Health Journal, at plumeapp.net, is a separate app. It is not affiliated with Plume: Private Journal & Diary (getplumeapp.com) or any other app or company called Plume.

Where is Plume available?

Plume is coming soon to the App Store in the United States, Canada, Australia and New Zealand. It is free and for adults, 18 and older. Press facts and logo files are in the press kit.
