CycleNest: Period Tracker

CycleNest is a private period tracker that keeps your cycle on your phone: no account, no cloud, encrypted on your device.

Log your period in one tap and CycleNest learns your rhythm. Your period calendar shows when your next period is likely, your estimated fertile window and ovulation, and how your cycle changes over time. Every prediction is worked out on your phone from your own logs and shown as an honest range.

Important: CycleNest shows estimates based on your own logs. It is not medical advice, not a diagnostic tool and not a form of birth control. Talk to a doctor or midwife about your health.
