Support — Haptic Knock

A 1:1 conversation connected through haptics.

Email: dive2ice@me.com

Quick help

Use a physical iPhone (Simulator has no Taptic Engine).
Turn off Silent / Focus modes that suppress haptics.
For realtime taps, turn the session on and keep the app open (a pocket can turn the screen off while the session stays awake).
Outside a session, knocks arrive as a notification. Open the app (or tap the inbox row) to play the pattern.

Use Sign in with Apple on the login screen. There is no password account.
Check network access and try again.
The App Store / TestFlight build always uses the production server. There is no API URL field in that build.

Create a 6-character code on one device; enter it on the other.
You can pair with several people. Each connection stays 1:1. There is no group chat.

Knock — send a saved pattern or the default TokTok to someone even if they are away. It waits in their inbox.
LIVE — open a session with one person at a time. Taps go through while both of you are in that session.
We do not keep custom vibration going forever on a locked phone.

App Store and TestFlight include the Knock watch app inside Haptic Knock. If a Watch is paired and Automatic App Install is on (the usual default), Knock installs on the Watch with the iPhone app.
If it does not appear: iPhone Watch app → My Watch → Haptic Knock → Install.
Sign in on iPhone first. The watch signs in from the phone.
Same rules: knock several people, LIVE with one. Watch alerts use system haptics; custom patterns play after you open them.

Settings → Delete account. This cannot be undone.

Include: iOS (and watchOS if relevant) version, device model, approximate time, and what you expected vs what happened.
