A food and mood journal that finds the patterns for you
Plume is a food and mood journal for iPhone: you write, say or photograph what you ate and how you felt, and after about a week it points out patterns between the two in your own days.
A food and mood journal is a record of what you eat next to how you feel, kept so you can see whether one follows the other. Plume keeps sleep and energy in the same entry, because they often sit between the two.
How do you keep a food and mood journal in Plume?
- One sentence is an entry. “Oat latte and two eggs.” “Foggy after lunch.” Type it, hold to talk, or take a photo of the plate.
- No lists to set up. Plume reads the entry and works out which parts are food, drink, sleep or mood. You see what it understood and can correct it.
- On Apple Watch, one tap logs a coffee, water, a snack or a mood: good, okay, low or stressed.
- From Apple Health, if you allow it, Plume can also read State of Mind entries (iOS 18 or later) and food logged in other apps.
What patterns does Plume look for?
Links between what you eat, how you sleep and how you feel, across your own days. For example: “Big dinners follow skipped lunches.” Each pattern says how many days it rests on and how sure Plume is. A correlation is called a correlation, and when there are too few days Plume says so instead of guessing.
You can also ask your journal questions, such as “How has my coffee changed this month?” The answer comes from your own entries and shows which ones it used.
Can you test a pattern?
Yes. Plume can turn a pattern into a small experiment of 7 to 21 days, such as a protein-first breakfast. It checks the days off from what you already log, and at the end shows what happened next to what you expected.
Does Plume count calories?
No. You never look up a food or enter a number, and there is no daily target. Plume keeps rough estimates in the background and labels them as estimates. If you need exact totals, a calorie-counting app is the better tool.
What is Plume not?
Plume is a wellness journal, not a medical device. It does not name conditions or give medical advice, and for those questions it points you to a doctor. Mood tracking can be turned off in Settings at any time.
Plume is free, runs on iPhone (iOS 17 or later) and is for adults, 18 and older. Common questions are on the support page.
