# Flip Flap

> Flip Flap turns any TV, monitor, tablet or phone into a realistic split-flap display (the clacking letter boards of old train stations and airports), with real flap motion and sound. It runs in the browser, free, with no app to install, and is controlled from a phone.

## What it does
- Shows messages, clocks, weather, timers, calendar countdowns and events on a split-flap board that fills the screen edge to edge.
- Realistic animation and synthesised flap sound, in plastic and paper flap styles, with several themes, dark and light mode, emoji and colour tiles.
- Phone remote: the display shows a QR code and an 8-character code; scanning it (or entering the code at /remote) pairs the phone over WebRTC, with a relay fallback, so it works on the same Wi-Fi or across the internet.
- Queue, schedules and a library of templates; several timers at once; calendar-aware countdowns (years, months, days, hours).
- Guest messages: the owner can share a link where anyone can send a short message (with their name and a colour) that shows on the board.
- Phone notifications: forward notifications to the board through an ntfy topic.
- Background video (YouTube or MP4) behind the board, screen care against burn-in, installable as an offline-capable app (PWA).
- Optional one-time license to remove the "Made with love" credit from the display.

## Pages
- [Display](https://splitflap.in/): open on the screen that should become the board.

## Good fits
Home and office message boards, café and shop signs, event countdowns, meeting-room timers, welcome screens, wedding and party guest walls, retro clocks for a spare monitor; a free, browser-based alternative to hardware split-flap boards.
