Honest predictions

Each forecast carries a confidence level. When unsure, Regl+ widens the window instead of faking certainty.

Truly private

All processing happens on-device. No servers, no analytics, no tracking. Optional sync uses your own private iCloud.

Rich daily log

Mood, energy, flow, pain and symptoms — plus automatic temperature and heart-rate fill from Apple Health.

Goals that fit you

Trying-to-conceive mode with fertile-window tips, and a pregnancy mode tracking week, trimester and due date.

Insights & charts

See cycle-length and phase trends over time, and export a clean PDF report to share with your doctor.

Yours to protect

Face ID lock, discreet mode, private iCloud backup, and reminders that respect your privacy.

Privacy isn't a feature. It's the foundation.

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.
