ClockX is more than a clock. It brings alarms, countdown timers, multi-timezone world clock and 400+ custom skins to your Windows desktop — all in a single lightweight app that starts in milliseconds.
Every feature is designed to stay out of your way. Right-click the clock to access anything — no menus buried in settings panels.
Set one-off or recurring alarms with custom sounds and labels. Each alarm can play audio, show a notification window, launch an application or even shut down your PC automatically.
Full alarms guide →Create quick countdown timers directly from the clock context menu. Perfect for Pomodoro focus sessions, cooking timers, meeting countdowns or any timed task. See the timers guide.
Display multiple time zones simultaneously on your desktop. Select any of the 34 supported language locales and track time across cities worldwide. Essential for remote teams. Full world clock guide.
Choose from 24 PNG and 7 BMP skins in the standard install, plus 98 additional PNG and 69 BMP skins in the full install. Both analog and digital faces. Advanced users can create their own skins using any image editor. Browse skins →
256 levels of transparency with special mouse-over transparency. Set the clock to stay always on top of other windows, or use click-through mode so it never interferes with your workflow.
Use global hotkeys to show or hide the clock, open settings or trigger alarms without clicking. Fully customizable from the Options menu. See the hotkeys guide.
Configure ClockX to launch automatically when Windows starts. Available per-user or for all users on the machine. No startup manager needed — it's built right into the Options dialog. Startup guide →
Place the clock on any monitor in a multi-display setup. It remembers its position across restarts. Works with extended and mirrored display configurations on Windows 10 and 11.
Written in C++ for minimal binary size and optimal memory usage. ClockX launches in milliseconds and uses far less RAM than any Electron-based alternative. No web runtime, no background services.
Beyond the core features, ClockX includes a handful of well-thought-out extras that make daily use more comfortable.
Click the clock to open a simple month calendar overlay. No integration with calendar apps — just a quick at-a-glance date reference.
Three anti-aliasing levels (off / method 1 / method 2) for smooth rendering of analog clock hands at any size and on any DPI display.
Full UI translation into 34 languages including English, Russian, German, French, Spanish, Chinese, Japanese, Polish and more.
Pin the clock so it sits at the desktop layer, behind all app windows but always visible. Great for clean desktop setups.
Set the process priority of ClockX in Task Manager terms: normal, high, real-time. Useful for animation smoothness on busy systems.
PNG skins use per-pixel alpha blending for smooth, shadow-like edges. The clock looks sharp on any wallpaper, light or dark.
ClockX works for a wide range of people. Here are the most common scenarios where it makes a real difference.
Run a 25-minute countdown timer directly from your desktop. When the timer ends, ClockX can play a sound or show a notification. Set shorter break timers between sessions. No separate Pomodoro app needed.
Pin world clocks for teammates in different cities so you always know the right time to schedule a call. Seeing three timezones at once on your desktop eliminates the mental overhead of calculating time differences.
Keep a transparent, always-on-top clock visible during presentations or live streams. Adjust transparency so it's readable but never distracting in screen recordings.
ClockX fills the gap left by Windows Gadgets. With 400+ skins and full transparency control, you can match the clock to any desktop wallpaper or Rainmeter theme. Compare with Rainmeter →
