CLUSTER CYCLE-PERIOD-TRACKER · 6 ENTRIES · EARLIEST ENTRY 2026-03-04

Couples period trackers

This cluster consists of period tracking apps that share a partner's cycle data to improve relationship awareness, targeting couples or men specifically. The dated history before the index start shows sparse entries: one in Dec 2025, one in Mar 2026, two in Jun 2026, and one in Jul 2026, a total of five—too thin to discern a meaningful shape. Traction is uniformly absent, as the three identified products—Her Signal, NerdCycle, and Period Tracker - MoodSwings—each hold 0 stars, so no clear leader exists.

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.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
