Period Tracking
Log periods, see your current cycle day and next period prediction, and understand your cycle — privately, with predictions that explain themselves.
Log in seconds
Record a period with its start and end dates, flow, and symptoms. You can also log symptoms and mood each day, and keep a private journal. Your history is preserved — changing a value never rewrites the past.
Predictions that explain themselves
Your next period is predicted from your own logged history. The prediction shows how confident it is and what data it rests on — not just a bare date. For irregular cycles, the prediction uses the mean of your last completed cycles and is labelled low-confidence when the data is thin.
Ovulation is always shown as an estimate, and the fertile window is shown around it. ORLENE never presents a prediction as a certainty, and never uses it to diagnose anything.
Gentle reminders
Get a reminder before a period starts, with quiet hours and per-category controls. Notification text is generic — it never puts health details in a notification.
