The free online clock suite — and why we built it.
VClock.pro is a free collection of timekeeping tools that run entirely in your web browser: an alarm clock, a countdown timer, a stopwatch, a world clock, a date countdown and a Pomodoro timer.
We built it because the simplest tools online had become the most annoying ones. Searching for something as basic as "10 minute timer" too often leads to a page that wants you to accept a dozen tracking prompts, install an app, create an account, or watch a video before it will count to ten. A timer should take one second to start.
Instant, with no friction. Every VClock tool works the moment the page loads. No sign-up, no email, no download, no permissions. Preset pages like the 5 minute timer start counting on their own so a bookmark becomes a single-click tool.
Genuinely free. There is no premium tier, no feature held back, no daily quota. The site is supported by advertising, which keeps every tool free for everyone who needs one.
Private by default. There are no accounts, so there is nothing to profile. Your alarms and saved cities are stored in your own browser using local storage and never sent to us. We cannot see what you set an alarm for, because that information never leaves your device.
Readable from across the room. Clocks are meant to be glanced at. Our displays are large, high contrast and tabular-aligned so the digits do not jump around as they change — a small detail that makes a real difference when a laptop is on the kitchen counter or the gym floor.
Everything runs client-side in JavaScript. Alarm and timer sounds are generated in real time using the Web Audio API rather than downloaded as audio files, which means there is nothing to buffer and the alarm never fails because a file did not load. Timing is calculated from timestamps rather than counted ticks, so a countdown stays accurate even when the browser throttles a background tab. The world clock uses the IANA time zone database built into your browser, so daylight saving transitions are handled correctly without any maintenance on our side.
Students timing revision blocks and exam practice. Cooks running three timers at once. Teachers putting a countdown on the classroom projector. Remote teams checking whether it is a reasonable hour in Berlin before scheduling a call. Athletes recording lap splits. Parents negotiating screen time with a visible clock. Night-shift workers who need an alarm at an hour no app suggests by default. All of them want the same thing: a clock that works immediately and then gets out of the way.
Alongside the tools we publish practical articles on our blog — how to wake up on time, how long a power nap should be, which alarm sounds work for heavy sleepers, and how to run the Pomodoro Technique properly. Everything is written in plain language, without the padding.
