Tips & tricks
An old phone or tablet gathering dust makes a perfect wall clock. Put it on a stand, open this page in fullscreen, and you have a sharp, glare-free digital clock with no app to install.
The display is built to be read from across a room — large, high-contrast, fixed-width digits. Because dark mode is automatic, it stays comfortable to look at overnight.
It reads the time straight from the device, so it is always correct and needs no setup — just open it and leave it.
