ClockX puts a fully customizable analog or digital clock on your Windows desktop — with alarms, countdown timers, world clock and 400+ skins. Completely free, no adware, no toolbars. Just a great clock.
Set one-off or recurring alarms with custom sounds. Create countdown timers for focus sessions, cooking or meetings — directly from the clock face.
Alarms guide →Track multiple timezones simultaneously. Whether you work with remote teams across continents or just need to call family abroad, ClockX shows every time zone at a glance.
World clock guide →Choose from over 400 analog and digital clock faces. Adjust transparency, size, and always-on-top behavior. Advanced users can edit skins with any graphic editor.
Browse skins →The taskbar clock tells you the time. ClockX gives you an always-visible desktop clock with tools that actually help you manage your day.
Unlike the taskbar clock, ClockX floats on your desktop — visible in any app, any window, any workflow. Pin it, make it click-through, set transparency.
Written in C++ for minimal resource usage. ClockX starts in milliseconds and uses less RAM than a browser tab. No Electron, no web runtime, no bloat.
Set alarms that can play a sound, show a window, launch an app or even shut down your PC. Recurring schedules work with no extra software needed.
Display several world clocks for different cities at once. Essential for remote workers, developers and anyone managing international schedules. See the full world clock guide.
Configure ClockX to launch automatically with Windows — for your user account or all users on the machine. No tray icons, no annoying pop-ups. More in the startup guide.
No trial, no subscription, no "Pro" tier. ClockX has been free since 2007. The developer asks only that you consider disabling your ad blocker on the official site.
The Windows Clock app is fine for quick time checks. ClockX is for people who want a clock that actually lives on their desktop. See the full feature comparison →
