One ring. Her whole month.
Her phase, the day she's on and what's next, at a glance. Log her period, symptoms or mood in two taps, right from the ring.

The cycle app built for partners
Cue learns her cycle from the little you log, then tells you what's coming: her mood, her energy, the hard days and the good ones, and one clear thing to do today.


Cramps usually start the day before her period (5 of her last 5 cycles). A heat pack goes a long way.
Irritability and bloating usually show up about 5 days before her period.
What Cue does
No charts to decode and no jargon. Cue turns where she is in her cycle into plain things you can actually do, and gets more personal every month.
Her phase, the day she's on and what's next, at a glance. Log her period, symptoms or mood in two taps, right from the ring.

Every period start you log replaces the guess with her real rhythm, so the ring, the calendar and every reminder line up with what actually happens.
No account and no sign-up. Everything you log stays on your phone and is never sold or shared.
The next two weeks: when her period is due and how much it usually varies, her fertile window, and when her PMS and symptoms usually start.

Timed from her own history, never a fixed calendar. At most one in the morning and one in the evening.
Expected around Thursday, usually within ±2 days for her.
Late-cycle days are when logging helps most. How is her mood today?
Trying for a baby? One switch reframes her fertile window as a conception window, with timing and a two-week-wait guide.
When each symptom and mood usually shows up around her period, and how consistently. The basis for every personal prediction.

46 short reads on her cycle, her mood and how to be useful. Every one cites its medical sources.
How it works
Her last period, and how long her cycle and period usually run. Two minutes, no account, and Cue maps the month ahead.
Two taps for her period, symptoms or mood. Every period you log teaches Cue her real rhythm.
Open Cue each morning for her phase, what's coming, and the three things that will matter most today.
The four phases
Each phase shifts her energy, mood and needs in fairly predictable ways. Cue colour-codes them so the pattern becomes second nature.
A look inside
Dark, calm and built to read in seconds. This is what you'll open each day.







Why Cue
Most period trackers are made for the person having the cycle. Cue is the rare one made for him: the boyfriend, husband or partner who wants to understand what she is going through and actually be helpful.
If you have ever wondered why her energy crashed overnight, why a small comment landed harder than usual, or which week is the right one to plan something special, that is the menstrual cycle at work. It runs roughly every 28 days through four phases, and each one shifts her hormones, mood, energy and needs in fairly predictable ways.
Cue turns that science into a simple daily read. Tell it when her last period started and how long her cycle usually runs, and it maps the month ahead: the phase she is in today, when PMS is likely, when ovulation falls, and three concrete things that tend to help right now. As you log, it learns her real rhythm, so the predictions get more personal every month. There is no medical jargon, and nothing she has to do.
When you want to go deeper, a growing Knowledge Base of plain-spoken guides covers her cycle, desire, communication and sexual health, all written for the partner and grounded in real science.
Cue is private by design, so everything you log stays on your phone, and it is free to start.

Yes. Cue starts from the basics you enter, then replaces them with her real averages as you log period starts: cycle length, period length and how much her cycles usually vary.
