Yori: Her Cycle, Understood

Yori is built for men — the partners, husbands, boyfriends, fathers and brothers who want to understand the menstrual cycle of someone they love, and show up better for her.

Most apps about the menstrual cycle are made for the person who menstruates. Yori is different. It gives you clear, science-based guidance for where she is today, what each phase of her cycle can bring, and how to support her — without guessing. AI-powered daily insights mean what you see is specific to her cycle right now, not generic advice.

No medical degree required — just the want to understand.

WHAT YORI HELPS YOU DO
• Understand her cycle phase by phase — period, rising energy, peak and wind-down
• Know when her period is expected, so nothing catches you off guard
• Get a personalised AI insight for exactly where she is in her cycle today
• Learn how to support her through the harder days — with empathy, not tactics
• Support more than one person — partner, daughter or sister — each kept completely private

REAL DEPTH ON THE CONDITIONS THAT MATTER
Yori goes further than any other menstrual cycle app for men on the conditions that shape so many women's lives:
• PMDD — premenstrual dysphoric disorder
• Endometriosis
• PMOS — polyendocrine metabolic ovarian syndrome, formerly known as PCOS
• Perimenopause and menopause
• Heavy menstrual bleeding

Every word is written to inform you, never to diagnose her — grounded in current clinical research, not folklore or guesswork.

PRIVATE BY DESIGN
Her menstrual cycle is sensitive information, and Yori treats it that way. There is no account, no sign-up and no cloud. Everything stays on your phone and nowhere else. No ads. No data tracking. Her data is never sold. You can even lock the app behind a PIN.
