Core tracking works without a login. Optional encrypted sync and partner sharing require an account inside the app.

How RhythmHer works

Less guessing. More context.

RhythmHer is a cycle companion—not a diagnosis or treatment tool. It helps you keep a private record, see estimates and patterns, and decide what leaves your device.

1

Check in your way

Log periods, flow, symptoms, mood, energy, sleep, and notes. Use taps, text, or the app’s voice check-in.

2

See the rhythm

Review cycle-day and phase estimates, a week view, calendar, and trends drawn from what you record.

3

Keep control

Your experience is local-first. Export a PDF or use optional encrypted sync and sharing only when you choose.

RhythmHer Partner

Share understanding,
not your whole diary.

You choose whether to connect and approve the short summary your partner sees. Raw entries are not shared. Your partner uses the separate RhythmHer Partner app to view that update.
