Clack is a split-flap board for your screen. Every letter is a real flap on a drum. Send a message and 132 of them spin, clack and land, with the sound and the feel of the physical boards you see in airports, hotels and homes. Then the board goes back to whatever you have scheduled: the time in words, the weather, tonight's scores, your calendar, a quote, or anything with a URL. MESSAGES Type anything and watch it cascade onto the board. Add colour chips with {red}, {green} or {blue}, or a heart. Pin a message so it stays. Send from the app, from Shortcuts and Siri, or from any other device on your network. CHANNELS Switch on the ones you want and the board cycles through them: • Clock, in words or digits • Weather, sunrise and sunset, air quality and UV, the moon • Football and sports scores with your team's colours, and the next fixture • Formula 1, Transport for London departures • Calendar and Reminders • Mail: unread count and the latest sender • GitHub commits, YouTube subscribers, crypto, stocks, exchange rates, App Store ratings • Hacker News, On This Day, any RSS feed • Custom API: point it at any JSON URL and write a template • Mirror the physical board on your wall Almost everything works without an account or a key. ON THE MAC Set the board as your live desktop wallpaper, behind your icons, on every Space, animating as messages arrive. Or install it as a screen saver. There's a menu bar composer, and a one-tap way to hide every window and just look at the board. FOR DEVELOPERS AND TINKERERS Clack speaks the same local API as the physical boards, so Home Assistant, Zapier, n8n, a cron job or a curl command can post to it unchanged. Send plain text or an exact grid of character codes. There's a built-in guide, and a prompt you can hand to your AI so it knows how to talk to your board. THE DETAILS • Flagship (6 × 22) and Note (3 × 15) layouts • Real flap physics: gravity on the fall, a damped landing, per-column stereo clacks • Realism mode: hinge pins, flap thickness, motion trails, print offset • Any typeface installed on your device, or import your own • Optional symbol flaps: arrows, weather, a few objects • Home Screen and Lock Screen widgets • Wall mode: the board alone on black, screen kept awake. Lean an iPad on a shelf. • Quiet hours, so the board sleeps when you do Made by OCTOBER.

Clackline puts a board of turning flaps on the screens you already have. Type a few words on your iPhone and they land on the Apple TV across the room, flap by flap, each one clacking as it settles. ONE BOARD FOR THE WHOLE HOUSE Every iPhone, iPad and Apple TV on your iCloud account shows the same board. Hang it on the living-room TV, stand an iPad on the kitchen counter, or give an old iPhone a second life on a shelf. There is no hub to buy, no account to create, and nothing stored on our servers. We don't have any. POST IN A FEW TAPS • A note for whoever gets home first • A task list with a colored chip for every job • Pictures made of colored tiles, drawn with a finger or made from a photo • Hold a word and drag it anywhere on the board • Quick sends for the things you say every day, and ready-made posts for birthdays and holidays • "Post to Clackline" with Siri TIMERS THE ROOM CAN SEE Start the pasta timer and it counts on the TV, your Lock Screen, the Dynamic Island and your Apple Watch at once. The last minute runs in giant digits, and the board celebrates when time is up. ON IPHONE DUO Stand it half open on the counter and the top half is a board of turning flaps, big enough to read across the kitchen, with quick posts and the timer underneath. Open it flat to see the board beside its rotation. Closed, the cover shows the board and the timer that's running. A BOARD WITH A DAILY RHYTHM Between posts, Clackline cycles through what you choose: the forecast, a countdown to the trip, a quote of the day. Rest hours let it sleep overnight. MAKE IT SOUND LIKE YOURS Every clack is synthesized and swept across the room as the words land. Start with classic flaps or wood.
