About ClockAura
ClockAura is a free, ad-light hub of online timers, stopwatches, pomodoros, alarms, world clocks and ambient focus sounds. The project is built and maintained by Om Vaghani, an independent developer in Ahmedabad, India, who wanted a single, beautiful place for every timing task — from a five-minute writing sprint to a ninety-minute deep-work block, from a HIIT workout cycle to a shareable countdown for a wedding. Everything runs in your browser, no sign-up is required, and we do not sell user data.
Our mission is simple. Timers should be simple. Whether you are a teacher running a classroom activity, a parent limiting screen time, an athlete training intervals, a cook waiting on eggs, a student using the Pomodoro technique, a developer in a deep work session, or a remote team scheduling across time zones — ClockAura aims to give you a fast, distraction-free tool that works on any device and any modern browser. Every feature is built around three principles: it works in your browser without an account, it stays out of the way of the timer you actually came for, and it respects your privacy by default.
Technically, ClockAura is a single-page application built with React, Vite and Tailwind CSS, served as static files from a LiteSpeed web server. The whole site runs entirely in your browser for instant response — the page loads, the timer is ready in milliseconds and continues running even when you switch tabs. Your preferences, saved picker lists, interval-timer presets and last-30-days of Pomodoro sessions are stored in your browser's localStorage against an anonymous client identifier — nothing is sent to a remote database, nothing is tied to your name or email. Sound is generated procedurally using the Web Audio API, which means no audio files to download and no streaming. Wake Lock APIs keep the screen awake when a long timer is running on mobile.
The site is fully responsive. The Classroom Mode in particular is designed for huge wall projectors so a whole room of students or athletes can read the timer from anywhere. The Random Picker doubles as a fair name-drawing tool for classrooms and teams. The Meeting Planner helps remote teams find an overlapping work window across multiple time zones. The Event Countdown creates a shareable link to any future date — popular for weddings, exams, product launches and personal challenges.
We rely on a small number of well-placed Google AdSense ads to cover hosting and maintenance costs. Ads never interrupt a running timer and they never appear on the Privacy or Contact pages. If you would rather skip ads entirely, installing ClockAura as a Progressive Web App caches assets locally so the site shows fewer network requests over time. Ad serving and Google Analytics 4 (with IP anonymisation) are the only third-party operations on the site — every other piece of functionality runs in your browser locally.
We read every contact-form message. Bug reports, feature ideas, partnership inquiries and press requests can be sent via the Contact page or directly to info@clockaura.com. We respond within thirty days. Follow ClockAura on X at @ClockAuraApp for product updates and behind-the-scenes notes.
