How would you draw the same prompt? Every day, a new prompt arrives. "What did you have for lunch today?" "What made you laugh the most recently?" "What’s something you want to tell your partner?" You both receive the same question and answer it with a drawing. Once both of you finish, your doodles are revealed, and you discover how differently the same thought can be seen. • One prompt every day What prompt arrived today? No need to wonder what to draw. Just answer the daily question with a sketch. Whether you've been together for 2 days or 2 years, every prompt sparks a new conversation. • Doodles revealed together You can only see your partner's drawing after both of you have finished. The excitement of opening your doodles and seeing two completely different perspectives on the same prompt is what Pingpong is all about. • A gentle nudge Haven't heard from your partner today? Send them a little poke. It's an easy way to say "Come draw with me" without sounding like you're nagging. • Your shared doodle diary Every prompt and doodle is saved.

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
