CLUSTER INTERVAL-TRAINING-HIGH · 49 ENTRIES · EARLIEST ENTRY 2009-12-23
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.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
