Cervical mucus, basal body temperature, menopause stages — Maya tracks all of it, and none of it is what you actually need.
More data isn't more help. Maya buries the one thing you need under dozens of things you don't.
Maya covers a lot of ground: periods, ovulation, pregnancy, and menopause, with symptom logging, basal body temperature, and cervical mucus tracking. It's a genuinely serious tool — for a woman managing her own health in clinical detail. None of it was translated for a partner; there's no dashboard turning any of that into what you actually need to know before you talk to her. Know Her throws out everything Maya tracks and keeps exactly one thing: her phase, her mood, her energy, and what that means for how you show up today.
One of these was never meant to answer your question.
Dozens of data points, and not one of them tells you what she needs from you tonight.
No account from her, no reading her phone. Know Her is fully yours, from day one — 100% offline, locked behind Face ID if you want.

What the app was built to solve changes everything about how it works.
Where your data lives is a design decision, not a technicality.
Know Her stores everything on your device. Period history, notes, settings — none of it is uploaded anywhere. There is no server holding her cycle data. You can lock the app behind Face ID, and the data stays entirely yours.
Maya is her own health-tracking tool, with detailed data about pregnancy, menopause, and daily symptoms living in her account. There's no partner-facing version of it — which also means there's no shared privacy model to compare, because you were never meant to be on the other side of it.
What it actually costs you.
Then $19.99/year (or $2.99/month). One app, one subscription — yours. No other accounts or plans required. Cancel anytime.
This is what she'd pay to track her own health in detail — there's no partner tier because there's no partner feature.
Only one of these is actually built for you to pay for.
