Every letter is a real flap on a drum. Send a message and 132 of them spin, clack and land. Then the board goes back to whatever you gave it.
A board for the weather, tonight’s scores, your calendar, the time in words, the space station, or whatever you type.
A channel is one thing the board knows how to show. Switch on the ones you want and it works through them, top to bottom, all day.
Type something and 132 flaps spin, clack and land. It holds for as long as you like, then the board goes back to its round.
Now and the next three days, from Open-Meteo. No key, no account. This is London, actually, right now.
Crypto, stocks, exchange rates, your GitHub commits, your followers. Prices here come from CoinGecko as you read this.
Headlines, on this day, any RSS feed. Long ones get shortened to fit rather than cut off mid-thought.
Not digits. The board says it the way a person would, which is the whole reason to have one on the wall.
Live scores while the match is on, in each club’s own colours, and the next fixture when it is not. Football, NBA, NFL, MLB, NHL and Formula 1.
Where it is right now and how fast it is going. It passes over most places a few times a day, and the board will tell you when.
Something that happened on today’s date, from Wikipedia. A different one every morning, and occasionally a very good one.
One purchase of nothing at all, on every Apple device you own.
The board sits at the desktop level, behind your icons, on every Space, and animates as messages arrive. Not a picture of a board: the real one, flipping while you work. Or set it as a screen saver, or let it write a fresh desktop picture each time it settles.
Wall mode drops every button, keeps the screen awake and fills it with flaps. Landscape is where a 22-column board really fits, so an old iPhone propped against your monitor becomes a departure board for your day.
A complication that carries whatever the board is showing, condensed to the lines that have something on them. Tap for the next channel, or turn the crown through them.
The whole screen is flaps. Swipe the remote for channels, and the local API is on from the first launch, so anyone in the house can post to the television from their phone.
On its way to the Apple TV App Store.
A board is twenty-two columns wide and the hinge falls between the eleventh and the twelfth, so the fold lands in a gap rather than through a letter. Open it and the board takes the full width with what’s coming up underneath; turn it and the controls move to the side, the way iPhone Duo asks them to.
Built for iPhone, iPad, Mac, Apple TV, Apple Watch and iPhone Duo.
No account, no tabs to learn. A board, the things you can put on it, and the settings for how it behaves.
There is no audio file anywhere in Clack. Every clack is made the moment it is needed, out of three sounds and an envelope, with the numbers nudged so no two are ever quite the same.
Choose a card to hear that part on its own.
The finish you pick for the board goes all the way to the Home Screen. The realism icon has the hinge pins, the tilt and the print sitting a hair off centre, same as the flaps do.
Black is the default and disappears in a dark room. Paper is an off-white gallery wall. Aluminium is bead-blasted, not brushed, so the grain is even in every direction the way the real thing is.
Black

AluminiumNot a shortcut to the app: the board itself on your Home Screen, flipping to your next channel when you tap it. The Action button, Control Centre and Shortcuts can move it on too.
The system faces, rounded, serif or monospaced, or drop in a font file of your own. Weight, width and size are yours too.
BBC, Guardian, Reuters, Hacker News, or any RSS feed you paste in. Headlines get shortened to fit rather than cut off halfway.
Football, NBA, NFL, MLB, NHL and Formula 1. Live scores while the match is on, and the next fixture when it is not.
Twenty-four templates in six categories, with the one word that is yours left blank. Fill it in against a live board and send it.
Search it, send it again, or start from it. The ones you starred and the ones you started and never sent are the same list, filtered.
Seven printed chips and nothing between them, so a gradient here is a quantised one. A band rolling across, rings opening out, or roughly the colour it is outside.
Any board you make goes out as a picture, framed and on its own black, so what arrives in the message is the object rather than a screenshot.
Scenes, weekday schedules and quiet hours. And a board on a wall changes a few times an hour rather than once a minute, then picks up again the moment you touch it.
Home Assistant, Zapier, n8n, a cron job or one curl can post to it unchanged. Send plain text, or the exact grid of character codes.
