About Clackline.

Clackline is a split-flap board for the room you live in. Post a message, a task list, a timer or a piece of tile art from your phone, and every Apple TV or iPad signed into your iCloud flips to it, one tile at a time, with the clack.

A rotation cycles what you've posted with live feeds: weather, scores, headlines, the next thing on your calendar, a countdown, a number you care about. Quiet hours and time-of-day rules keep it sensible. Siri posts for you: "Post to Clackline."

No accounts and no server. Boards sync through your own iCloud, so a phone and a TV in the same house agree without talking to us. Meant for kitchens, living rooms, offices and small shops.

Take the full tour at clackline.com.

Post from your phone

Type it, send it, watch it flip.

Home is a composer with the board's live preview above it. Messages, task lists, art and timers each get a tab; six colour chips and a dozen pictograms drop in as tokens. Quick sends keep "Dinner is ready" one tap away, and Send later puts a post on the wall at the moment you choose.

It flips, and it clacks

One hundred and thirty-two tiles, sixty frames a second.

Every change ripples across the board left to right, each tile on its own slightly different beat. The clack is synthesized, not sampled, sized to how many tiles are moving, in your choice of sound pack: classic, wood, steel, soft, or handbells and sleigh bells for the holidays. Pinch to change the flap size; the phone or iPad can be the display too.

A list the whole house can see

Chores, groceries, the plan for Saturday.

Post a task list and it lands on the board with a check for each thing that's done. Tick items off from the phone and the wall keeps up.

A timer you can read from across the room

Pizza dough, homework, the last ten minutes of screen time.

Countdowns and Pomodoros are posts like any other, in three looks: a giant flip clock, a bar of tiles that goes dark minute by minute, or a sun that sets as time runs out. Every screen agrees on the time, and a handbell rings at zero even if the sound is off.

Tile art

A rainbow, a sunset, a photo turned to flaps.

Paint a picture in chips, pick a preset, or hand it a photo and let Flapify dither it onto the grid. Emoji become pictograms: a heart, a star, a cake, a tree, a snowflake, in whatever colour you typed.

Every screen, in step

iPhone, iPad and Apple TV, one board.

Boards sync through your own iCloud. Each screen picks the board it shows, the rotation cycles posts and live feeds on a schedule you set, quiet hours keep the wall dark at night, and Siri, Shortcuts and the Action Button post without opening the app. On the TV, the remote opens a small menu for boards, rotation, timers, flap size and sound.
