Each forecast carries a confidence level. When unsure, Regl+ widens the window instead of faking certainty.
All processing happens on-device. No servers, no analytics, no tracking. Optional sync uses your own private iCloud.
Mood, energy, flow, pain and symptoms — plus automatic temperature and heart-rate fill from Apple Health.
Trying-to-conceive mode with fertile-window tips, and a pregnancy mode tracking week, trimester and due date.
See cycle-length and phase trends over time, and export a clean PDF report to share with your doctor.
Face ID lock, discreet mode, private iCloud backup, and reminders that respect your privacy.
We built Regl+ so that we never see your data — not your periods, not your symptoms, not your predictions. There is no account to create and no server to send anything to. Read exactly how it works in our Privacy Policy.
