About SetAlarm

SetAlarm is a free, browser-based suite of time tools designed for one simple goal: putting a beautiful, readable clock or timer on any screen. Whether you need a classroom countdown timer, an operations center wall clock, a meeting stopwatch, or just a quick alarm — SetAlarm does it without downloads, sign-ups, or clutter.

The idea came from a common frustration: existing online timers and clocks are either packed with ads that obscure the display, look dated, or lack basic features like fullscreen mode and font customization. SetAlarm was built to be the tool you actually want displayed on a 65-inch TV in a conference room — clean, modern, and fully customizable.

Every feature runs entirely in your browser. Your settings are saved locally on your device, and nothing is sent to a server. The alarm sounds are generated programmatically using the Web Audio API, so there are no audio files to download and no copyright concerns.
