Workout interval timer apps

This cluster consists of interval and round timer apps for structured training (Tabata, boxing, martial arts, breathing exercises, etc.), centered on configurable work and rest phases with audio and vibration cues. The dated entry record shows a long, sparse tail: one entry per month scattered across roughly 17 years from 2009 to 2026, with a slight uptick in April-May 2026 when two entries appear each month. On traction, powerbreathe-pacer leads by a small margin, with 1 star, while other named leaders have no stars.
