About KnowWhen

Hey husbands—stop guessing. KnowWhen gives simple guidance based on her cycle so you can support her better, at the right time.

Most relationship tension isn’t about effort. It’s about timing.

KnowWhen helps you respond with more understanding—when to listen, when to give space, and when to lean in.

What you’ll get:

- Daily, simple guidance (not essays)

- Phase-based reminders so you’re not guessing

- Optional private logging to spot your own patterns over time

- Built for discretion: your data stays on your device

KnowWhen helps you know when to…

• Give space
• Offer support
• Listen instead of fix
• Lean in
• Reconnect

Privacy first. No accounts. No cloud. No tracking.

Important

KnowWhen provides informational insights. It is not medical advice and not a medical device. It describes population-level tendencies, not a guarantee of your partner's behaviour.

Guess Less. Connect More.
