Yori: Cycle & PMDD for Men

Most cycle apps are built for the woman having the period. Yori is built for the man beside her.

If you've ever known something was off and had no idea what to do about it, this is the context nobody ever gave you.

WHAT IT ACTUALLY DOES

Yori turns where she is in her menstrual cycle into plain guidance for you: what this stretch tends to bring, what she may be experiencing, and how to be useful without guessing or hovering.

If you've searched for a period tracker for men, Yori is something different. You're not monitoring her. You note what you see, and over time Yori builds a picture of what her cycle actually looks like for her — not the textbook average.

BUILT AROUND REAL CONDITIONS

Dedicated, science-backed guidance for PMDD, endometriosis, PMOS (formerly PCOS), heavy periods, perimenopause and menopause. Written from peer-reviewed research and major medical bodies — never blogs or forums.

THE FOUR PHASES, IN PLAIN ENGLISH

Period, Rising Energy, Peak and Wind Down — with the clinical names (menstrual, follicular, ovulation, luteal) alongside, so you learn the real terms as you go. Each phase gets its own posture, because what helps in one is wrong in another.

WHOEVER YOU'RE SUPPORTING

Partner, wife, girlfriend, daughter, sister, mother or friend. Set she/her, they/them or he/him per profile, and everything follows.

QUIET BY DESIGN

Two notifications per cycle. Not two a day. Yori speaks up when there's something genuinely worth knowing — a harder stretch approaching, or a pattern it's spotted — and otherwise stays out of your way.

HER PRIVACY IS THE POINT

No account. Nothing uploaded. Everything stays encrypted on your phone. Her participation isn't required, and she never has to use the app or hand over anything.

FREE, AND WHAT ISN'T

Phase guidance, all six condition guides, the calendar, logging and cycle notifications are free forever.

Your first AI insight starts a 14-day full-access trial — no card needed. After that, daily AI insights and the Patterns screen need Premium, from £3.49/month. Everything you've logged stays yours either way.

WHAT IT ISN'T

Not a way to manage her. Not a manual for winning arguments. Not a tool for deciding how she feels. Yori's rule is ask, don't assume — and the app will tell you so, often.
