About iAlarmClock
What we do
iAlarmClock is a free collection of time-related web tools — an alarm clock, countdown timer, stopwatch, and world clock — that run entirely inside your browser. There is no app to install, no account to create, and no fee to pay. Open a page, use the tool, close the tab. That's the entire experience.
Why we built it
Most online clock and timer sites are slow, cluttered with intrusive ads, demand permissions they don't need, or push you toward downloading an app. We wanted the opposite: a single, fast, lightweight site where each tool does one thing well, loads in under a second, and respects your privacy.
How it works
Every tool runs as static HTML, CSS, and JavaScript in your browser. There is no backend processing your data, no server storing your alarms, no cloud sync. Your alarms and preferences live in your browser's local storage on your device — clear your browser data and they're gone. Nothing about how you use the tools is sent anywhere.
How we make it free
iAlarmClock is supported by display advertising. We use Google AdSense to serve ads on some pages, which keeps the tools free to use. We do not sell your personal data, run paywalls, or push affiliate offers inside the tools themselves. If you'd like to support us further, share the site or send us a note.
Who's behind it
iAlarmClock is an independent project run by a small team. We're not backed by a venture firm and don't have a roadmap full of "features" you didn't ask for. Decisions are simple: does this make the tools faster, more reliable, or more private? If yes, ship it. If not, skip it.
