CLUSTER SLEEP-ALARM-CYCLES · 18 ENTRIES · EARLIEST ENTRY 2012-03-23

Smart alarm clock apps

This cluster comprises 18 mobile apps centered on smart alarms, sleep tracking via phone sensors, and gentle wake-up features like gradual volume or light-sleep timing. The dated history before the index start spans 15 entries from 2011-11 to 2026-06, appearing as a slow, irregular trickle of roughly one entry per several months rather than a concentrated burst. Traction leaders by activity signal are Sleepfy: Sleep Tracker, Alarm Clock HD, and alarm, though all show zero stars.

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.
