Clock.app is a simple, accurate, ad-free digital clock.
It's a digital clock, does what it says on the tin, etc. That said, it does have some basic features:
Any changes you make will change the URL in the address of Clock.app, so you can bookmark or copy or share the clock with your preferred options.
The h=
parameter in the URL controls the hue (color) of the clock. You can set it to any value between 0 and 360. For example:
https://clock.app/?h=23 will display the clock in a reddish color.
For devices which support Dark Mode, the clock will automatically switch to a darker theme while maintaining the selected hue. This makes it easier on the eyes in low-light conditions.
Clock.app gets its time from a server rather than your device. This ensures accuracy, as device clocks can drift over time. The server synchronizes with Network Time Protocol (NTP) to maintain precise time. This means that Clock.app will show the same time across all your devices, synchronized to within a few milliseconds.
Still, it won't be perfectly accurate because of various things like light travel time between you and the Clock.app server, thermal fluctuations in your devices, spacetime curvature anomalies, etc.
Clock.app makes us of the Luxon JavaScript time library in order to display the correct time for your timezone and pick the right locale in choosing whether to show time in 24 hour format.
There are no ads on Clock.app and it is free to use.
