Clackboard
Read full descriptionHide full description
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 β 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" β 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 β 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 β 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 β swipe sideways to switch between clock, message, countdown and scoreboard. CLACKBOARD PRO β BUY ONCE, KEEP FOREVER β’ 8 more designs, including Deluxe in 3D β’ Countdown, also as a widget β’ Scoreboard with your own team names β’ Your own messages on rotation β’ Video clips with sound and high-res images β’ No subscription, Family Sharing included No ads.

Verdict
The clearest difference is ads: Clackboard at none against Flip Clock's shown. Flip Clock's advantage is iOS requirement (13.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.
