Irregular Timer
A timer that runs segments of different lengths in order — like 3 minutes, then 2, then 5 — playing a sound at the end of each one and looping back to the start when the list finishes.

How to use
Add each segment's name and duration in order in the segment list. Lengths can all be different, and you can reorder them with the up/down arrows.
Click "Start" and a sound plays at the end of each segment as it automatically moves to the next one.
Set a repeat count, or leave it at 0 to run forever until you stop it, and save a setup you use often as a preset.
