CLUSTER PERIOD-CYCLES-MENSTRUAL · 228 ENTRIES · EARLIEST ENTRY 2005-12-02
Menstrual cycle tracking apps
This cluster comprises mobile and desktop applications that help users monitor menstrual cycles, predict ovulation, log symptoms and moods, and often provide fertility insights, reminders, and privacy-focused on-device storage. The dated history begins in December 2005 and shows a steady but irregular cadence of new product entries, becoming more frequent in the years just before the index began (e.g., 2026-01, 2026-04). Traction leaders (siklusku, Mooneva Period & Cycle Tracker, Lunara: Period Tracker) all have zero stars, indicating no product has yet emerged as a frontrunner.
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.
