A free, beautifully crafted online timer and clock suite — built to make managing time feel calm, not stressful.
TimerMo is a free online timer that runs entirely in your browser — no downloads, no sign-up, no clutter. Set any duration up to 99 hours, switch on Pomodoro mode for focused work sessions, or count up toward a target instead of down. Eleven calming alarm tones are synthesized live in your browser, so nothing needs to load.
It’s designed around a single idea: a timer should feel premium and effortless, with just enough features to be powerful and none of the noise that gets in your way.
Click the display to set any duration, from one second to ninety-nine hours.
One tap for the classic 25-minute work, 5-minute short break, and 15-minute long break cycle.
Count up from zero toward a target — ideal for workouts, study, and meditation.
Instant timers from one minute up to forty-five minutes, a tap away.
Add a custom note that appears when your timer ends.
Pause and resume with accurate timing, even when you switch browser tabs.
Every sound is synthesized in real time with the Web Audio API — no audio files, no harsh beeps. Choose the one that suits your moment:
Volume and alarm duration are both adjustable, and you can preview any tone with a single tap — even while a timer is running.
