Shared timer options
Sound cues apply to every timer in the list.
Multiple Timers
Run several independent countdowns with individual names, durations, controls, completion states, and optional sound.
When several countdowns help
Run separate timers for multiple dishes, classroom activity stations, workout intervals, study tasks, meeting agenda segments, or household jobs. Each timer can be started, paused, reset, named, or silenced independently, while group controls handle the full list.
Multiple timers vs other timing tools
Use the Countdown Timer when only one duration matters. Use the Timer and Stopwatch when you need one countdown and an elapsed-time mode, or an Interval Timer when one structured sequence should advance through planned intervals.
Timer names, durations, remaining values, and sound settings are saved in local browser storage on this device. This route does not add analytics capture for timer names or entered values, and it does not use accounts or cloud synchronization.
The browser storage guide lists this route's exact key and explains why restored timers are paused rather than treated as continuously running.
Run independent countdowns
Each row has its own label, duration, start state, and alarm. Start all begins every ready timer. Reset all restores each timer's configured duration. Stop alarms silences any completed timers without changing other running rows.
Set Timer A to 5 minutes and Timer B to 10 minutes. Start both together. Timer A reaches zero first while Timer B continues with about five minutes remaining. Adding or removing a row affects only that timer.
Local restoration
Timer definitions and selected state use local browser storage. There is no account sync or cross-tab coordination. A restored page can reconcile saved timing data, but a closed tab cannot deliver a durable background alarm. Device sleep may delay sounds until the browser resumes.
