A real split-flap board on your iPhone: flip clock, message board, countdown and scoreboard in one. Every flap falls with gravity, catches the light, casts a shadow, hits the stop and bounces – just like the departure boards at the station. CLOCK Stand your iPhone sideways on its charger and it becomes a split-flap desk clock. 12 or 24 hours, with seconds and date. At night the board can dim by itself. MESSAGE "Coffee?", "Do not disturb", "Delayed by about 5 min" – type what the board should say and watch every flap run through the alphabet until your text stands. COUNTDOWN How long until your vacation, a birthday or the end of the workday? The board keeps count. SCOREBOARD Table tennis in the garden, the match on TV, a game night: two teams, their names, points and sets. Tap or swipe down for a point, pull the flap back up to take it away – every point is one flap. WIDGETS & STANDBY The clock, your message and your countdown on the Home Screen and in StandBy, the countdown also on the Lock Screen – your iPhone on the charger becomes a split-flap clock. IPHONE & IPAD One purchase for both. An iPad on the desk or on the wall makes a big departure board. ON THE BIG SCREEN Mirror your iPhone to the TV with AirPlay or a cable, and the whole room can read the board. DELUXE IN 3D Real plastic flaps, rendered live in 3D: light, shadows, reflections and a little wear, like a board that has hung in a station for years. DESIGNS Deluxe, Station, Airport, Night Train, Retro, Brass, Signal Red, White and Terminal. Pick one from the menu – swipe sideways to switch between clock, message, countdown and scoreboard. CLACKBOARD PRO – BUY ONCE, KEEP FOREVER • 8 more designs, including Deluxe in 3D • Countdown, also as a widget • Scoreboard with your own team names • Your own messages on rotation • Video clips with sound and high-res images • No subscription, Family Sharing included No ads. No account. No data collected.
