What's inside

Cycle & ovulation predictions

Adaptive predictions that get sharper every cycle you log — not a flat 28-day guess.

Pregnancy mode

Announce you're expecting and Home itself switches — week-by-week development, a due-date wheel, tailored articles.

Share with up to 5 people

Give a partner, a parent, or a doctor their own code to see your full calendar and daily logs, read-only. No account needed.

Symptom correlation

See which symptoms cluster before your period, and when — patterns most trackers never surface.

A real article library

Cycle basics, trying to conceive, pregnancy, LGBTQ+ & family building, and more — free for everyone.

Your data isn't the product

Health data is never sold or shared with advertisers, and every log is protected by row-level security enforced at the database.

Start tracking in under a minute.
