Know Her vs
Maya

Cervical mucus, basal body temperature, menopause stages — Maya tracks all of it, and none of it is what you actually need.

★  Only what matters to you
Know Her period tracker app — home screen widget showing her cycle phase

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.


Who each app is actually for

One of these was never meant to answer your question.

Maya

  • Built for her to self-track in detail. Symptoms, BBT, cervical mucus, pregnancy and menopause stages.
  • No partner mode. Nothing in the app shows any of this to someone else.
  • Dozens of data points irrelevant to you. Most of what Maya tracks has no bearing on what a partner actually needs to know.

Dozens of data points, and not one of them tells you what she needs from you tonight.

Know Her

  • The date her last period started. That's it. You set it up, you own it, you control it.

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.

Design intent matters

What the app was built to solve changes everything about how it works.

Know Her

  • ✓ Phase names and descriptions written for men
  • ✓ Dashboard: energy, mood, tips in plain language
  • ✓ Practical daily guide — what she might need from you
  • ✓ Calendar built for at-a-glance reading, not medical logging
  • ✓ Widget: one-tap phase check from the home screen
  • ✓ Notifications timed so you're prepared, not caught off guard

Maya

  • ✓ A thorough, detailed health tracker — for her own use
  • ✗ Covers pregnancy and menopause — outside what a partner needs day-to-day
  • ✗ No dashboard, widget, or notifications for a partner
  • ✗ No concept of "what should the partner expect"
  • ✗ Nothing designed for a man to check in a few seconds
  • ✗ No private notes layer for a partner

Privacy: local vs cloud

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.


Price comparison

What it actually costs you.

Know Her Free to download — full access for 14 days

Then $19.99/year (or $2.99/month). One app, one subscription — yours. No other accounts or plans required. Cancel anytime.

Maya $24.99–$49.99 her Silver/Gold plan, per year

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.


Common questions

About choosing between Know Her and Maya.

No. Maya is a comprehensive women's health app covering periods, ovulation, pregnancy, and menopause. It tracks symptoms, basal body temperature, and cervical mucus for the woman using it — there is no view, dashboard, or feature designed for a male partner. Know Her was built from day one for that exact purpose.
Not in any built-for-you way. Maya has no partner sharing mode — it's a self-tracking app with dozens of data points meant for the woman logging them. Know Her strips all of that away and shows only what a partner needs: her phase, her mood, her energy — without needing her account or her data.
Yes. Know Her stores everything on your device — no account, no cloud, no sync. All data stays on your phone.
Know Her is free to download, with a 14-day trial that includes full access, then $19.99/year (or $2.99/month). Maya's own premium plans run from $24.99/year (Silver) to $49.99/year (Gold), or $2.99-$5.99/month — but that's the price of tracking her own health in detail, not a partner feature.
No. Know Her works entirely from information you enter yourself — no account for her, nothing to install, nothing to share. You just need the date her last period started. She doesn't even need to know you're using it.
Yes. Everything stays on your phone — no account, no cloud, no sync, nothing to leak. You can lock the app with Face ID or biometrics for extra privacy on top of that.
You get 14 days of full access, completely free. After that, Know Her runs on a simple subscription — monthly or annual. Cancel anytime directly in your App Store settings.
No. Know Her is designed to help you understand and plan around her cycle — it's not a medical device, diagnostic tool, or method of contraception. For health decisions, always consult a healthcare professional.
