Haptic Knock

Haptic Messenger

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

Instead of words, a check-in with haptic vibration. Knock several people; talk live with one. iPhone and Apple Watch sense it. Away? A knock waits. No groups, no feed. 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. An optional purchase is needed only if you want to copy a pattern into their library. Knock, LIVE, and receiving patterns stay free. • Pattern share unlock — one-time non-consumable • Only the sender unlocks. Receiving and accepting stay free. • Restore purchases in Settings. 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
