Pomodoro Timer
Why does Pomodoro Timer stay at 00:01 before finishing?
Pomodoro Timer rounds positive remaining time up to the next whole second, so 00:01 can mean anything from one millisecond to one second remains. Pause preserves the underlying milliseconds. If the deadline has already passed when you press Pause, the app finishes the interval instead of freezing an expired countdown.
Read 00:01 as a remaining fraction of a second
The countdown displays minutes and seconds, but the timer keeps its remaining time in milliseconds. Its formatter divides that value by 1,000 and rounds upward. This means 1,001 milliseconds appears as 00:02, while 1,000 milliseconds and 250 milliseconds both appear as 00:01. Zero milliseconds appears as 00:00.
The last visible second therefore does not mean the timer has stopped. It covers the final positive remainder. The same rule applies at a minute boundary: 60,001 milliseconds displays as 01:01, and 60,000 displays as 01:00. Read the digits as a rounded countdown rather than a measurement showing fractions of a second.
Separate display updates from elapsed time
The app requests a countdown check every 250 milliseconds. Each check subtracts the current clock time from the interval deadline; it does not simply remove a second whenever a callback runs. A deadline is established when you start or resume, using the current time plus the remaining milliseconds.
This distinction explains a jump in the visible digits after a delayed update. For example, if a check finds 2,100 milliseconds remaining, the display reads 00:03. If the next check happens with only 900 milliseconds left, it reads 00:01. The app has recalculated the remainder rather than promising to show every number. Background and sleep delays can affect when that update becomes visible, and device clock changes can affect the calculation itself.
Expect a short displayed second after Resume
Pause first recalculates the remaining time, then preserves it if the interval is still running. It does not round the stored remainder to match the digits. If you pause with 250 milliseconds left, the paused display reads 00:01. Waiting while paused does not consume that remainder.
When you select Resume, the new deadline is the current time plus those same 250 milliseconds. The display can reach zero at the next check after that remainder elapses. It does not owe you another full second just because the paused digits showed 00:01. Use Pause to preserve the actual remainder; the displayed seconds are a readable approximation of it.
Check the state if a late Pause finishes the interval
If the screen still shows a positive number when you press Pause, the click handler calls the timer's pause method. That method checks the deadline before changing the state to paused. If time has already run out, the check sets the remainder to zero and marks the interval finished. The subsequent pause step leaves that finished state alone.
Look for FINISHED and 00:00 rather than assuming the click froze the old number. After a focus interval, the button becomes Start break; after a break, it becomes Start focus. A focus completion also adds one to the session count. Later timer checks do not add further completions because they immediately return unless the timer is running.
That late Pause click does not also start the next phase: the click handler chose its running branch before checking the deadline. Read the updated button and choose the next interval when ready. These details explain the display and controls from the source; they are not a guarantee of precisely timed background alerts. The app has no sound or system notifications.

Frequently asked questions
Does 00:01 always mean a full second is left?
No. The formatter rounds upward, so any positive remainder up to 1,000 milliseconds displays as 00:01. The stored time can be much shorter than the displayed second.
Does pausing repeatedly add extra seconds?
Pause does not round the stored time upward. It checks the deadline and preserves the remaining milliseconds; Resume creates a new deadline from that remainder. Display rounding does not add time to the timer.
Why did Pause become Start break instead of Resume?
The pause method checks for expiry first. If the focus deadline has passed, it finishes the focus interval and the button becomes Start break. That click does not start the break; selecting Start break does.
