Clackboard: Split-Flap Clock

Wear a station departure board. Every digit of the time sits on its own flap card, and when the minute changes the cards really flip: the top leaf folds down over the hinge and the new digit drops into place.

FEATURES
• Real flip animation at every minute; the hours flip when the hour turns
• Detailed flap cards: a darker lower leaf, the hinge line with axle pins, the edges of the waiting flaps underneath
• Timetable layout: the date on little letter flaps, big time cards, and five board rows for your data
• Big cards layout: four big cards (hours over minutes) above your two data rows
• Large, high-contrast numbers and values, readable at a glance
• Two customizable complication slots, shown in both layouts

DATA SHOWN
• Date
• Two complication rows, steps and heart rate by default (swap in any data your watch offers)
• Timetable layout also: weather now with today's high and low, chance of rain, battery with a green or red status lamp

SETTINGS
• Layout: Timetable / Big cards
• Board: 11 color schemes (airport yellow, classic, royal blue, station green, cream, signal red, midnight amber, mint, ice blue, copper, violet)
• Time cards: dark or colored flaps
• Motion: On / Still
• Glass glare: Off / On (a soft band of light sweeps the glass)
• 12- or 24-hour time follows your watch setting

BATTERY
Between flips the board is completely still: no frame-by-frame animation, so it costs about as much as a static face. The always-on screen is true black and lights less than 10% of the pixels: hollow card outlines with outlined digits and dim values. Choose Motion: Still for instant digit changes.

COMPATIBILITY
Works on Wear OS 5+ watches (Pixel Watch, Galaxy Watch …). Built with the Watch Face Format. It is a watch face only, with no phone app.

HOW TO CUSTOMIZE
Long-press the watch face, then tap Customize (or use your phone's watch app) to pick the layout, board, flap style and complications.

PRIVACY
This watch face collects no data. Weather, steps and heart rate come from your watch and stay on it.
