FLAPPI
Essential minimal app

Turn any TV into
the board from the airport.

Those letters that clatter over on a departure board. Now a menu, a countdown, the weather, or a message your room sends from their phones, in most languages. The real ones cost thousands and hang in one place. This is $49 and runs on any screen you like.

MenuPrices you change from your phone

That is SplitMotion™, running live. Not a video, not a GIF.

Why this exists

It started in an airport.

I love travelling, and the best thing in any terminal was never the lounge. It was the board. That sound when a whole wall of letters turns over at once, and everyone looks up.

So I set out to find how they work, and got completely obsessed. I pulled apart footage of real Solari boards frame by frame: how long a flap takes to fall, where it slows, how a letter settles, why a row ripples instead of turning all at once. Get any of that wrong and the eye knows straight away.

SplitMotion™ is what came out of that. Every flap, timed against the real thing. Then all the parts a mechanical board cannot do: every language, every symbol, every emoji, any size, on a screen you already own.

The physical boards cost thousands, ship in months, and hang in one place. This is the same beautiful thing, on the television behind you.

Every room with a screen in it.

Give each TV a name and it shows its own board. The menu in the kitchen, the welcome at the door, the countdown behind the bar, all from one Mac and one licence.

Cafés and bars

The menu, changed from your phone while the queue is still at the door. Happy hour turns itself on at five.

Hotels and offices

A guest welcomed by name, the hours, what is next in the calendar, and an alert that takes every screen at once.

Events and weddings

The room writes to the board from their own phones, and nothing appears until you allow it.

Streamers

A transparent overlay straight into OBS. Follower goals, now playing, countdown to going live.

Shops

Prices, offers, opening hours, and the weather that is about to walk through the door.

Home

The school run, whose turn it is, and a message waiting on the kitchen TV for whoever gets home first.

Everyone else sells you a wall.

A mechanical board is a beautiful object. It is also a machine with hundreds of moving parts, hanging in exactly one place.

It breaks, and you pay

Flaps, motors and bearings wear out. Repairs mean parts, a service call, or shipping the thing back.

You cannot turn it down

The noise is the mechanism. Reviewers stop talking while it turns over. Ours has a volume, and an off switch.

One wall, forever

Fixed size, fixed place, fixed number of characters, decided the day it was built. Want a second room? Buy a second board.

The good bits cost extra

$119 a year for the content feeds on top of $3,499 for the board.

Or you rent, per screen

The software rivals start at nothing and then charge every month, for every screen. Ten TVs is about €200 a month, forever.

FLAPPI

$49 once. Every screen you own. Nothing to break, nothing to service, and you can silence it.

Everything it does.

All of it works today. The three marked MAC read something living on your own computer, so those need the app.

What goes on the board 15
MenusSections, several price columns, dotted leaders, automatic paging, and a happy hour that turns itself on and off.
CountdownsTo a date, or to a time that comes round again, rolling on to tomorrow by itself.
Clocks12 or 24 hour, seconds, any date format.
World clocksSeveral cities at once, for anyone whose work is somewhere else.
WeatherFeels like, today's high and low, rain chance, humidity, UV, wind.
PricesCrypto and stocks with the move in green or red, and your own holdings.
News and feedsHeadlines on any subject, or any RSS feed you already read.
MessagesAnything you want said. Any language, emoji and special symbols included.
AlertsTakes over every screen the moment you press it, then hands the rotation back on its own.
Calendar MACCounts down to your next real event.
Now playing MACWhatever Music or Spotify is playing.
Mail and messages MACThe newest one, shown with a name rather than a number.
Social countersFollower and subscriber counts on the wall.
Mac batteryFor a machine driving a screen somewhere awkward.
WebhooksAnything else you can send from another system lands on the board.
What the room can send 2
Audience screensPolls, trivia, Q&A, guest book, confessions, anonymous messages and dare requests. A QR code appears on the board. A guest points their phone camera at it, taps once, and is typing. Their message, vote, question or dare arrives for you to approve. No app to download, no account, nothing to install.
ModerationNothing reaches the wall until you allow it. A rude-word filter across about twenty languages catches the obvious and the disguised, with an optional second opinion from Google.
How it looks 5
LanguagesMost of them. Arabic and Hebrew run right to left properly. Thai, Chinese, Japanese, Korean, Greek, Cyrillic. Emoji on the flaps.
SoundThe real clack of the flaps, with a volume control, or silent.
GridFrom 10 to 48 columns and 3 to 24 rows, up to 1,152 flaps. Or switch on fill and the board stretches to the exact shape of the screen, portrait or landscape.
ColourBackground, letters and accent, for the whole board or one screen at a time.
Display modesFullscreen, screensaver, wallpaper, or a transparent overlay for streaming into OBS.
Running it 8
Screens per licenceUnlimited. Name a TV and it shows its own board.
Runs onmacOS 14+, iPad, or any browser. Send it to a TV or monitor over wifi or a cable.
Phone controlScan, approve the device on the Mac, and it is the same editor in your hand. Save it to the home screen and it opens like an app.
BoardsSeveral open at once as tabs, saving as you type. Close one and it waits in saved boards; delete it and the bin holds it thirty days.
UndoForty steps, and every version of the board kept on the Mac.
SchedulingAny screen can run only on chosen days, between chosen hours, or take the whole board while it does.
NetworkEverything local stays on your own wifi. No account needed to run a menu, and no internet needed either.
UpdatesFree, forever, signed so nothing else can pretend to be one.

Buy it once.

That is the whole idea.
