Knock-Knock Support

Q. I can't find Knock-Knock on my watch.
Make sure your iPhone and Apple Watch are paired, then open the Watch app on iPhone and install Knock-Knock from “Available Apps.” If the version number has not changed, remove the old build from the watch before installing.
Q. Why am I not getting any knocks?
Open Knock-Knock on the watch first and allow notifications. Then open the About screen on iPhone and check the “Watch” line for authorized, synced, and scheduled: on the Terminal skin tap about in the top right; on the Windows 98 skin choose “Help › About Knock-Knock.”
Q. Can I change the time or number of knocks?
No. Knock-Knock always knocks three times a day at random, between 9:00 a.m. and 10:00 p.m. For hours when you do not want to be interrupted, use watchOS Sleep or a Focus.
Q. Are my questions uploaded anywhere?
No. Questions are stored on your devices and sync only between your own iPhone and Apple Watch. See the privacy policy for details.
Q. Still stuck. How do I get in touch?
Open an issue on GitHub. Do not include private or sensitive information in an issue.
