Knobble: Draw with Friends
One line, drawn together
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Send a drawing that draws itself. One unbroken line, passed back and forth with friends — each turn in your own color. Plus, a new shape to trace together every day.
Knobble is a tiny drawing toy that lives in your Messages.
You draw ONE unbroken line — with two little knobs, or just your finger — and send it to a friend right inside iMessage. They watch it draw itself, stroke by stroke, then pick up the pen exactly where you left off and keep the same line going in their own color.
That's the whole magic: every Knobble, no matter how many people add to it, is a single continuous line. Pass it back and forth and watch a goofy doodle slowly become... something. A cat? A boat? A beautiful mess? All of the above.
ONE LINE
Each person's turn is a new color, but the line never lifts. Receiving a Knobble isn't just an image — it animates itself drawing, then hands you the pen.
TWO KNOBS OR YOUR FINGER
Twist the two knobs like a classic mechanical drawing toy (left moves across, right moves up and down), or just draw with your finger. Same line either way — pick whatever's more fun.
A NEW CHALLENGE EVERY DAY
There's a fresh shape to trace every day — a heart, a rocket, a snail — and it's a two-person relay: you trace the first half, a friend finishes it, and you get a score for how close you landed together. Share the result.
MADE FOR GROUP CHATS
Couples, best friends, family threads, chaotic group chats. The more people who add a turn, the better (and weirder) it gets.
NO ACCOUNTS, NO TRACKING, NOTHING TO SIGN UP FOR
Knobble has no servers and collects nothing about you. Your drawings ride inside the message itself, sent peer-to-peer through Messages. There's no feed, no login, no data collection — just you, your friends, and one ridiculous line.
KNOBBLE PLUS (optional, one-time)
Love it? Knobble Plus is a single one-time purchase (no subscription) that unlocks:
• Trace a Photo — fade one of your own photos behind the canvas and trace it together
• Every device color — pick the color of your Knobble toy
• A premium pen palette — more colors to sign your turns with
Everything Plus draws still shows up in full color for the friends you send to, whether or not they have Plus. The core — draw, send, watch, continue, daily challenge — is free forever.
Open Messages, tap the Knobble app, and draw your friend a line.
