Plume with Apple Health, Apple Watch and Oura

Plume is a health journal for iPhone that, with your permission, reads what your devices measure from Apple Health and shows it next to what you wrote, so your words and your numbers sit on the same day.

What does Plume read from Apple Health?

Only what you allow, in Apple’s own permission sheet. Plume can ask for:

• Sleep, steps, workouts, exercise minutes and active energy
• Resting heart rate, heart rate variability and sleeping wrist temperature
• Weight
• Food and drink logged in other apps, such as energy, protein, carbohydrates, fat, fibre, sugar, sodium, caffeine and water
• State of Mind, on iOS 18 or later
• Menstrual flow, only when cycle tracking is on
• Medications, on iOS 26 or later, each asked for separately

Plume never writes to Apple Health. It never reads basal body temperature, ovulation tests or cervical mucus. After you agree in the app, mostly summaries such as daily totals and sleep times are sent to Plume’s server. The Privacy Policy has the details.

What does the Plume Apple Watch app do?

It is for logging in a second. The home screen has four tiles, Coffee, Water, Snack and Mood, and a Talk button for a spoken note. Each tap becomes an entry on your iPhone, read there without opening the app. If the iPhone is out of reach, the Watch keeps the entry until it can send. The Watch app needs the iPhone app and watchOS 10 or later.

Anything your Apple Watch measures, such as sleep and heart rate variability, reaches Plume through Apple Health.

Does Plume work with Oura?

Through Apple Health. If your Oura app shares its data with Apple Health and you let Plume read it, Plume shows it next to your entries, the same as data from an Apple Watch.

What does Plume do with the numbers?

It puts them next to what you said about the same day and looks for patterns across both, such as drinks the day before a morning with lower heart rate variability. Each pattern says how many days it rests on and how sure Plume is. Plume does not take measurements itself.

Do you need a watch or a ring?

No. Plume works from what you write, say or photograph alone, and the Apple Health step can be skipped. How Plume differs from using Apple Health on its own is on Plume vs Apple Health alone.
