A few things to know
Keep the page open while timing an activity. If you return to the tab or reload, the saved time is used to catch up. Changes to the device clock while the page is hidden may affect the result.
On return, targets up to 60 seconds late ring once. Older targets are marked missed. Sound may need permission again.
Check tab mute, device volume and Bluetooth output. Notifications are not required.

How do stages and cycles work?
Enter one stage per line as a name followed by | and a duration in seconds. Choose a cycle count to repeat the sequence; a late return skips missed stages rather than playing a burst of old sounds.
