Rattleboard

Rattleboard is a split-flap message board for your home. Every flap clatters through its drum, one character at a time, in a black or white finish, with an optional mechanical clack.

Give an old iPhone, iPad or TV a second life as a board on the kitchen bench, in the hallway or on your desk, then send it messages from your phone.

SEND TO ANY BOARD
• Type a message and see it laid out exactly as the board will show it: upper case, word-wrapped and centred.
• Add colour chips, or paint a grid tile by tile.
• Pick a transition: classic, column, row, diagonal, edges to centre or random.
• Send to one board, a group such as "Downstairs", or all of them at once, with a result for each board.
• Drafts, templates and your recent messages are kept on the device, so you can resend or edit any of them.

TIMED SEQUENCES
• Build a sequence of up to 100 frames, each with its own hold time and transition: a morning routine, a countdown or tonight's menu.
• Loop it, preview it on your phone, and play it on a board.

PAIR IN SECONDS
• On a Rattleboard TV or desktop, choose Pair a phone and scan the code. The board's key is saved in the iOS Keychain.

WIDGETS AND FULL SCREEN
• Small, medium and large home-screen widgets show what a board is displaying.
• Full screen turns the iPhone or iPad itself into a board, with the screen kept awake.

SHORTCUTS
• "Send to Rattleboard" and "Play sequence" actions for Siri and the Shortcuts app, so an automation can post to your board.

TRY IT WITHOUT HARDWARE
• Demo mode shows a rotating set of sample messages, so you can explore everything before you set up a board.

PRIVATE BY DESIGN
• No accounts, no ads, no analytics and no tracking. Messages go straight from your device to your boards on your home network.

One price, paid once. No subscriptions and no in-app purchases.
