## What is Know Her?

Stop guessing how she feels.
Luteal phase? Estrogen surge? Follicular window?
You don't need to know any of that.

Built for partners who want to better understand, support and connect — without awkward conversations, confusing medical terms or guesswork.

10-second setup.
That's it.

Start understanding what is happening now, what is coming next, and when she may need more patience, space or support.

You don't even need to open the app.
Everything is available directly from the Home Screen widget.

Try free for 14 days.

BUILT FOR PRIVACY

Everything stays on your device.

No account.

HOW IT WORKS

Know Her uses logged cycle data to estimate upcoming phases and important transitions.
