The beautiful, offline-first cycle tracker. Log your days, predict your fertile windows, and stay in sync with your body—all securely on your own device.
Three simple steps to better understand your body.
Just tap the calendar when your period starts. Add any symptoms, moods, or notes to keep track of how you feel.
Our app learns your unique cycle length. We'll automatically estimate your next period and ovulation windows.
Check the dashboard to see your cycle averages, track symptoms over time, and know exactly what phase you're in.
Most trackers sell your data. We don't even collect it.
Everything you log stays securely on your phone. No cloud servers, no databases, no tracking.
You don't need an email or password to use the app. Just open it and start tracking immediately.
You own your data. Download it anytime to switch devices or share with your doctor.
