Description
Haptic Knock is for two people who want a private way to say “I’m here” without typing a whole chat.
You pair once with a short code. When you both start a session, taps on the pad go through as vibration on the other phone—same timing, same feel as close as the hardware allows.
You can also save a few short patterns (goodnight, miss you, whatever you invent) and send them later. If the other person isn’t in a session, they get a knock notification; opening the app plays what you sent.
Sign in with Apple. You can delete your account in Settings.
A straight note on limits: live tapping works while the session is open in the foreground. We don’t keep vibrating forever on a locked phone. When someone’s away, it’s notification first, then play after they open the app.
