Frequently asked questions
How do I turn the end-of-session alert on or off?
In the app, open Settings → Notifications and switch Focus notifications on or off. Because the alert is a system notification, you can also manage it from your phone's own notification settings for Shimpaku.
Why didn't the alert sound?
Your phone's silent mode or Do Not Disturb setting can prevent a notification from making a sound, even when it's enabled in the app. The completion sound played inside the app (while it's open) also follows your device's silent mode, and can be turned off separately under Settings → Completion sound.
My tree isn't growing
A tree grows in stages based on the number of finished sessions, not on the amount of time spent. Extending a session by an extra 10 minutes does not count as an additional session, and ending a session before 20 seconds have passed does not count at all.
Can I change trees?
Yes. Each tree keeps its own growth progress, so switching between trees does not affect the others.
I'm changing phones. What happens to my progress?
Shimpaku does not sync between devices. Whether your progress carries over to a new phone depends entirely on whether your old phone's system backup (iCloud or Google) included the app's local data, and whether you restore from that backup.
Does Shimpaku work offline?
Yes, completely. The app does not need a network connection for anything.
How do I delete all my data?
Open Settings → Reset all local data in the app. This removes your settings, trees, and session history from the device. Uninstalling the app has the same effect.
