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. IPHONE DUO Your iPhone Duo becomes a bedside clock, and Clackboard works out how it is standing. Half-folded on a table, the clock stands on the upper half with a reflection below. Propped half-open on its edges, like a book stood up, the left side shows the hours and the right side the minutes, and the fold stays clear. As a tent, the clock uses the full width of the outer display. In the night hours the board turns amber, with no clacking and no seconds; on a table the lying half is a dimmer – swipe up or down. Without a charger, a quiet notice appears below 20 % battery. You can switch the night light off in Settings. With Pro, the Duo also shows a second time zone, one clock per half, and becomes a scoreboard pad: on the lying half each team gets a big field – tap for +1, swipe up for āˆ’1; propped on its edges, Home is on the left and Guest on the right. Nothing changes on other iPhone models. 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, also as a pad on iPhone Duo • Second time zone on the clock • Your own messages on rotation • Video clips with sound and high-res images • No subscription, Family Sharing included No ads.
