How Anlan works
In short: you start a meditation on Apple Watch and meditate as you usually do. While you meditate, the watch records your heart rate and the small movements of your wrist. Afterwards, Anlan estimates on your own devices whether your body settled, roughly when, and for about how long. You see the result on iPhone. Nothing is uploaded.
Using it
- Start on Apple Watch. Choose a length with the Digital Crown, from 5 minutes to 3 hours, then press and hold the screen to begin.
- Meditate. The screen stays dim, with no numbers and no taps. Gentle taps build when time is up, unless you chose not to be woken this time.
- See whether your body settled. The full result appears on your iPhone.
What data it uses
- Heart rate measured by your Apple Watch while you meditate.
- Small movements of your wrist, from the watch's motion sensors.
- Breathing, estimated from those wrist movements.
- Your own references: your usual heart rate while awake and your heart rate while asleep, from Health, so each meditation is read against your own baseline.
How it judges
Using machine learning on your Apple Watch and iPhone, Anlan estimates every few seconds whether your body has become stable. Your body counts as settled only once it has stayed stable for a while; brief ups and downs don't count.
What you get
- Whether your body settled.
- About when it settled, rounded to the minute.
- About how long it stayed settled.
- Breathing, estimated from wrist movement, when it can be read.
- Your lowest heart rate, next to your usual and asleep heart rate.
- If you fell asleep at night, the minutes your watch recorded as sleep are marked asleep and don't count as settled.
- How certain this result is. When Anlan is less sure, it says “about”; when it can't tell, it says so.
Recorded, estimated, not judged
| Recorded | Estimated | Not judged |
|---|---|---|
| How long you meditated | Whether your body settled | How focused you were |
| Heart rate from Apple Watch | About when, and about how long | How deep the meditation was |
| Breathing, when it can be read | Your state of mind |
A settled body often goes with a calm mind, but not always. Anlan reports only what your body did. How well it does that is on Accuracy and limitations.
What we publish
The model's features, parameters and architecture are proprietary. We publish the data sources, the evaluation method and what every number we quote means.
Not a medical device. Results are estimates.
