Your guide to Kamosu

Record a mood

On the Ferment screen, choose Calm, In between, or Tense, then tap the green save button. Notes are optional. Return adds a new line.

Your vessel’s appearance

Every day with a mood entry or saved health estimate advances maturity equally. Each day counts once, and 22 recorded days reach 100%. You can then keep the vessel on your shelf. Days without records neither advance nor reduce maturity. Moods influence the color of your vessel.

Apple Watch

In Settings, open Apple Watch & Health, allow read access, and enable automatic updates. At least 7 days of baseline data and new resting data for today are needed. Updates happen when you open the app, and manual moods take priority. This experimental feature is being tested on devices; it is not a medical measurement or diagnosis.

Changing devices

Use Export journal on your old device, then Import journal on the new one.

Purchases and languages

The four basic kinds are free. Four Vessels is a one-time purchase for sourdough, amazake, kimchi, sauerkraut. In Settings → Extra vessels, use Restore purchases with the same Apple Account. Exported journals do not transfer purchase rights.

Kamosu supports Japanese and English. It follows your device or per-app language setting. Your own notes and vessel names are kept as written.
