What is a flip clock?
A flip clock shows the time on number cards that flip down when the time changes, like the split-flap boards once used at train stations and airports. This page recreates that motion on screen.
My screen still goes dark in full screen
In full screen the page asks the browser to keep the screen on using the Screen Wake Lock API. It may not work in browsers without support, in power-saving mode or when the battery is low. In that case, lengthen the screen timeout in your device settings.
Full screen doesn't work on my iPhone
Safari on iPhone does not let a page put part of itself in full screen, so the clock fills the browser window instead. Turn the phone sideways for a bigger clock. On iPad, Android and computers it fills the whole screen.
The time seems to be off
The clock shows this device's time. If the device clock is wrong, so is the display. Turn on “Set date and time automatically” in your device settings.
The flipping motion is distracting
Turn off “Flip animation” in the display settings and the digits will change without moving. If your device is set to reduce motion, the animation starts turned off.
