Yori gives men science-based, day-by-day awareness of what the women in their lives may be experiencing — so showing up with the right kind of support becomes a little easier.
"You can tell something's off, but you don't know what.
You try to help and it lands wrong.
You back off and that's wrong too.
You're not clueless — you just don't have the context."
Most men go through their entire relationship without understanding how a cycle shapes her energy, mood, and experience — not because they don't care, but because nobody ever explained it to them. Yori changes that.
How it works
No complicated setup. No data to hand over. Just a clearer picture of where she might be, and what that means.
That's the only thing Yori needs to get started. It calculates which phase she's in today — and shows you what that typically means in terms of energy, mood, and experience.
Each day, Yori gives you a short, grounded insight based on where she is in her cycle. Not a prediction of how she'll feel — just what the science says is common, and one thing that tends to help.
Over time, brief notes about what you observe build a picture of her specific patterns. The more you log, the more personal the insights become — less about biology in general, more about her specifically.
The cycle
Understanding the phases isn't about predicting her. It's about knowing what she might be carrying — so you can respond rather than react.
Energy is lower, discomfort is common. Small gestures — warmth, presence, less pressure — tend to matter most here.
Energy and mood are building. Often a good time for plans, conversations, and decisions she's been putting off.
Often her most energetic and sociable phase. Warmth and connection tend to peak. Show up — she's likely at her most open.
Energy and mood can shift significantly, especially toward the end. Gentleness and patience tend to matter most here.
Six conditions supported, each with dedicated guidance written with care — not clinical detachment.
What's inside
Not a one-time read. Something you actually open.
A short, grounded insight each day — based on her phase and what you've logged. Specific to today, not generic phase information.
See her predicted phases laid out over the coming weeks. Useful for planning, for travel, for knowing when to be more present.
Quick mood and energy taps, or free-text notes. Over time these build a picture of her unique patterns — not just average biology.
Support more than one person — a partner, a daughter, a sister. Each profile is completely separate.
Detailed, honest guides to PMDD, Endometriosis, PMOS, and more — written for someone who loves the person living with it.
She may be more sensitive to noise and cold today.
"Seemed tired this morning, didn't want to talk much"
Day 2 is often the hardest. Offering warmth without pressure — a quiet evening, her choice of plans — tends to land better than words right now.
"I built Yori because I wanted to understand what my wife goes through — not to predict her or gain some kind of advantage, but to genuinely show up better. I was surprised there wasn't already something like this that took it seriously. So I built it."
Scott, founder of Yori
