Everything here is stored in this browser only. Each person who opens the page has their own six timers and their own Logs, so nobody affects anyone else's times. Keep the tab open while you work. If you reload or close it, running timers keep their real time.
Minutes: type a number, tap a preset, or leave it empty for a stopwatch. While a countdown runs, use +5 and +15 to extend it. Press Done to save the ticket to Logs.
When you apply a note, the timer counts from the Started time in the note, so the minutes already used are not lost.
