Period and pregnancy trackers

This cluster comprises comprehensive period and pregnancy trackers that log cycles, predict ovulation, track symptoms, send reminders, and offer baby development tools, with some products adding on-device privacy or partner sharing. Dated entries before the index start appear sporadically from 2011, with entries in 2011, 2013, 2022, 2025, and multiple in 2026, suggesting a more active period in recent years. The traction leaders—Fertility: Period Tracker, Period Tracker: Cycle & Baby, and IVY Period & Pregnancy Tracker—each have zero stars, indicating no clear market leader.

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.
