About StopwatchPlus
StopwatchPlus is a set of free timing tools that run entirely in your browser: an online stopwatch with laps and CSV export, a countdown timer with preset lengths, a Pomodoro timer with adjustable focus and break lengths, and an interval timer that announces work and rest rounds in sound.
The one idea behind the site is that browser timers should not drift. Every clock here measures time from real timestamps instead of counting timer ticks, which is the trick cheap timer widgets get wrong. The accuracy page explains how it works — and where the honest limits are.
There are no accounts and nothing to install. Lap data, settings and countdowns exist only in your open page (Pomodoro lengths are kept in your browser’s local storage so they survive a revisit). StopwatchPlus is built and maintained by ORBITFRAME as part of a family of small, single-purpose free tools.
