Support

Chawan is a matcha brewing and journaling app: a guided brew timer with a tin journal, recipes, and a caffeine curve, all synced through your own iCloud with no account required.

Frequently asked questions

iCloud sync isn't showing my data on another device

Make sure both devices are signed into the same Apple ID and have iCloud enabled in the iPhone's Settings app. In Chawan, go to Settings -> iCloud and check the sync status. Sync can take a few minutes, especially the first time. If it still hasn't appeared after a few minutes, try closing and reopening Chawan on both devices.

How do I restore my Chawan Pro purchase

Go to Settings -> Chawan Pro -> Restore, while signed into the Apple ID you used to buy it. This does not charge you again.

How do I delete all my data

Go to Settings -> iCloud -> Delete all data. This removes your tins, brews, and journal entries from the device and, if sync is on, from your iCloud account. You can also delete the app itself to remove its on-device data; to remove anything already in iCloud, use your iPhone's Settings -> [your name] -> iCloud -> manage storage.

Are the caffeine numbers exact

No. The caffeine and L-theanine curve is built from published averages for matcha, coffee, and tea, plus the servings you log. It is an estimate, not a lab measurement of what you drank, and it is not medical advice.

My reminders aren't firing

Check that notifications are allowed for Chawan in the iPhone's Settings app, then check Settings -> Reminders inside Chawan to confirm the reminder you expect is turned on and its time or threshold is set the way you want. Quiet hours, if enabled, will suppress reminders during that window.

The Live Activity on my Lock Screen isn't updating

The timer and progress bar on the Live Activity are drawn directly from the brew's start and end time, so they stay correct on their own. The step label (sift, water, whisk, serve) needs the app to briefly stay active in the background to update; if iOS reclaims the app under memory pressure, that label can lag behind. The step will still sound at the right time through a local notification, and the timer itself stays accurate.
