Plume press kit
Plume is a health journal for iPhone that looks back over your days for you; this page has a short description, the facts, and logo files.
What is Plume, in one paragraph?
Plume is an iPhone app where people record food, sleep, mood and energy in their own words: by typing, talking or taking a photo. There are no forms and no calorie counting. What someone logs appears as a small still life of objects on that day’s page. After about a week, Plume starts pointing out patterns from the person’s own days, says how many days each one rests on and how sure it is, and can set up small experiments to test them. Plume is a wellness journal, not a medical device.
