Read full description

Haptic Knock is a 1:1 app for conversations that happen only through haptic vibration — not a chat thread. Connect with several people separately, and leave a knock as a check-in. Live conversation is with one person at a time — as clear as a call. Haptic Knock is for people who lead with rhythm, not words. Couples, long-distance, friends, family. No group chat, no feed. Every connection stays 1:1. Get started • Sign in with Apple. There is no password account. • Pair with a 6-digit code. • You can pair with several people. Each person has their own knock inbox. Knock — a check-in for several people Send “goodnight,” “miss you,” or the default TokTok even when they’re away. A notification waits; opening the app plays the vibration. LIVE — real time with one person Turn on a session with that person and taps on the pad go through to their iPhone. Starting LIVE with someone else ends the previous session. Apple Watch The Knock watch app is inside the iPhone app. If Automatic App Install is on, it installs with the phone. Alerts use system haptics; saved patterns play after you open them. iPhone and Apple Watch sense the knock. Patterns Save short rhythms and send them again later. Leaving a pattern in their library is free. Knock, LIVE, and pattern share stay free. • Pattern share — free • No in-app purchase • They accept it into their library Honest limits • Live taps work best with the session on and the app in front. • A pocket can turn the screen off while the session stays awake. • We don’t vibrate forever on a fully locked screen. • When away: notification → open the app → play. Change your display name or delete your account in Settings. Contact: dive2ice@me.com
